Environmental elements like heat, light, and oxygen can degrade and harm the material over time, but plastic stabilizers can act as a shield to protect them. Using the proper plastic stabilizing agent is essential to preserving the usability and safety of the product.
Polymer stabilizer needs to be strong, work well with plastic, and be able to withstand certain climatic conditions throughout its life. When these stabilizers are applied correctly, their overall performance, longevity, and safety are greatly enhanced.
Let’s follow along to understand more about this plastic addition!
In order to improve the material’s qualities and protection throughout processing and ultimate usage, plastic stabilizers are essential additions to the manufacturing of plastic. They guarantee plastic’s resilience and longevity by halting polymer deterioration caused by outside influences like light, heat, humidity, or oxygen. Plastic stabilization is essential in industrial applications where resistance and durability are necessary.
Heat stabilizers are used to increase PVC products’ stability and resilience to heat during processing. They are classified as lead-based stabilizers, calcium-zinc, organic tin, calcium-zinc composite, and organic tin/calcium-zinc hybrid.
Selecting the right heat stabilizer is essential since every type meets different needs and has different performance characteristics. For instance, calcium-based stabilizers have become more popular as a result of health and environmental concerns.
A number of factors, including end-use applications, processing circumstances, and regulatory compliance, influence the choice of heat stabilizer. With proper plastic stabilizers and technical assistance, manufacturers and processors can create great benefits for their businesses.
Another popular polymer stabilizer is antioxidants. They are chemicals that prevent polymers from reacting with oxygen, a process known as oxidation. Their role is to stop free radicals from forming, which can start chain reactions that degrade polymer chains.
Antioxidants protect plastics from degrading and preserve their chemical and physical characteristics by obstructing these processes. Over time, bacterial degradation of plastics can be avoided with the correct antioxidant mixture.
The next type to mention is a light or UV stabilizer. UV stabilizers are crucial for preventing plastic from deteriorating as a result of exposure to the sun’s UV radiation. They stop plastic from degrading by absorbing UV radiation and turning it into heat.
Because they assist in prolonging the life of objects exposed to outside elements, they are frequently used in outdoor products including garden furniture, car components, and building materials.
Besides the above plastic stabilizers, more additives are used to enhance the durability and lifespan of products.
For example, the mechanical and chemical qualities of thermoplastic polymers, such as PVC, polyethylene, and polypropylene, are preserved by the use of thermal stabilizers. The additive helps polymers avoid breakdowns at high temperatures.
Or another type is lubricant stabilizers. It’s an internal lubricant or processing aid used in plastic processing to improve flow characteristics, lower friction, and stop polymer deterioration. In turn, it benefits the smooth extrusion and molding processes and increases production efficiency.
Plastic stabilization can bring lots of benefits, including:
By shielding products from deterioration caused by external elements including heat, moisture, and sunshine, plastic stabilization increases product lifespan. Since it lowers the need for replacements, it results in reduced waste and financial savings.
By acting as UV absorbers, plastic stabilizing agents protect users from prolonged exposure to dangerous UV rays. They also lessen the chance of fires or explosions by preventing flammability or ignition.
Polymers can be greatly degraded without the use of plastic stabilizers. Plastic stabilization helps products resistant to the impacts of heat, light, and chemicals and maintains their structural integrity over time.
By prolonging product longevity, decreasing frequent replacements, and lessening environmental effects, plastic stabilization lowers manufacturing and end-use costs. By concentrating on stability and investing in high-quality stabilizers, manufacturers can guarantee the long-term performance of their plastic products.
Plastic stabilizers are a solution in many industries, including:
In order to improve appearance, flexibility, and lifespan as well as to protect against heat, oxidation, and UV degradation, plastic stabilizers are widely employed in the manufacturing of consumer items including toys, furniture, and home appliances.
The performance and utility of plastic packaging materials are enhanced by the use of polymer stabilizer, which guarantee flexibility, durability, and protection against oxidation, heat, and light-induced deterioration.
The stabilizers are used in many electronics applications, such as circuit boards, connections, and casings.
The performance and longevity of plastic parts used in automobiles are greatly improved by stabilizers, such as UV stabilizer, for protection against heat and UV rays.
These additives are used in the construction industry to improve the weather resistance and longevity of plastic materials used in roofing, insulation, pipelines, and fittings.
Consider these factors so that you can choose the most suitable stabilizer:
Consult with your team to find out what stabilizer is required according to the unique chemical properties of the chosen plastic.
Depending on where you want to use your final products, the stabilizer should be appropriate. For example, if your plastic is exposed to high temperatures, a heat stabilizer can be an ideal option. For outdoor applications, it’s best to add a UV stabilizer as well.
Manufacturers should consider processing temperature and compatibility of stabilizers with other additives to eliminate undesired issues such as discoloration or premature degradation.

Color stability is one of the criteria to choose a stabilizer to avoid discoloration of the products in the future. Besides, you should consider if the stabilizer may influence the plastic’s mechanical properties, such as strength and flexibility.
Plastic stabilizers are widely available. Yet, we suggest you purchase from trustable suppliers, such as EuP Egypt, to guarantee quality for your final products.
Since plastics are mostly inexpensive and easy to process, they are widely used in many industrial fields. However, not all the resins meet the requirements of the final products. Understanding this fact, EuP Egypt introduces a wide selection of plastic additives to improve production efficiency and end-product functions.
Plastic additives from EuP Egypt are applied during the production process to guarantee the material is high-performance when molded and used. Since these substances decrease friction between materials and the machine wall, they allow more high-performance manufacturing. Plus, they improve the capability to be resistant to different environmental conditions, as well as the durability and longevity of plastics.

Since they offer protection against various factors, they maintain and enhance the necessary quality for plastics to survive in different environments.
PVC STABILIZER enables polymer compounds to be used without structural changes in the presence of heat, light or oxygen, for example during processing, storage or use of the product. It is also possible to break chains or crosslinks and deteriorate properties.
It is therefore necessary to add an appropriate Heat Stabiliser during processing so that the structure of the polymer compound is not damaged or its ring breakage is prolonged and the quality of the product is stabilised. This added substance is commonly known as Pvc Stabilizer.
Stabilisers manufactured by Shandong Polymer Additives are divided into heat stabilisers, light stabilisers and antioxidants according to their effect on heat, light and oxygen, of which Heat Stabilizer is the most important additive for pvc.
Polyvinyl chloride (PVC) has the advantages of good acid and alkali resistance, abrasion resistance, electrical insulation, non-flammable and self-extinguishing and low price, making it a very widely used thermoplastic. Despite its many advantages, PVC has a fatal disadvantage, namely its poor thermal stability. PVC usually starts to degrade when heated to 140°C, while its processing and moulding temperature is around 160-200°C. Therefore, Heat Stabilizer must be added to inhibit the degradation of PVC during processing and moulding.
Pvc Heat Stabilizer is mainly used for PVC and other polymers containing chlorine. If the PVC plastic contains small amounts of impurities such as lead salts, metal soaps, phenols, aromatic amines, etc., it does not affect its processing and application, but also serves to retard its thermal decomposition to a certain extent.
The ideal PVC structure is the first-tail structure - CH2-CHCl - CH2-CHCl-, which is quite stable. However, the synthesis of PVC is not yet possible in the same way as the synthesis of cis-butadiene, which is subjected to directed and regular polymerisation under the action of a zigzag catalyst.
The polymerisation of vinyl chloride is a random polymerisation of free radicals, which, in addition to a stable first-tail structure, has a first-head structure -CH2-CHCl-CHCl-CH- and a last-tail structure -CHCl-CH2-CH2-CHCl-; there is coupled disproportionation to produce vinyl junctions CH2 =CH-CHCl-CH2- structures and allyl chloride -CH2-CH=CH-CHCl-CH2 etc.
PVC is easily degraded during processing precisely because of the instability in the structure of the PVC molecular chain, which decomposes at a temperature of about 130°C without stabilisation. However, to process PVC resin into useful products, the moulding temperature has to be above 190°C. Therefore, heat stabilisers must be added to improve the structure.
Heat Stabilizers are a class of Pvc Stabilizers that prevent or reduce the degradation or cross-linking of polymers by heat during processing and use, extending the life of the composite material. commonly used Pvc Stabilizers can be classified as salt-based, fatty acid soaps, organotin compounds, complex heat stabilizers and pure organic compounds according to their main components.
Pvc Heat Stabilizer is an excellent heat stabiliser. It has good compatibility, low volatility, low migration and good light resistance. It is suitable for soft pipes, granulation, calendered films, toys, conveyor belts, advertising cloth, wallpaper and other PVC products.
Pvc Stabilizers can be added directly to PVC or in blends to prevent oxidation, chain breakage, uncontrolled recombination and cross-linking reactions caused by photo-oxidation. Essentially, they protect PVC from the harmful effects of extreme temperatures and UV radiation.
A Pvc Heat Stabilizer is a heat stabiliser for polyvinyl chloride and its copolymers. Classification is generally based on the chemical composition of the heat stabiliser, which can be alkaline lead salts, metal soaps, organotins, epoxy compounds, phosphite esters, polyols, etc. PVC stabilisers can be divided into primary and secondary stabilisers according to their role.
Barium-zinc additives are very effective Pvc Heat Stabilizers, but are limited to medical applications in some countries. Alternatives such as calcium-zinc formulations are often used to stabilise the heat resistance of medical grade PVC.
a. Liquid Barium-Zinc Compound Stabilizers
It is generally a light yellow to yellowish brown oily liquid with a specific gravity of 1.0-1.1 at room temperature, good heat resistance, not contaminated by sulphide, and can be used with epoxy plasticizers to improve the stabilization effect.
b. Liquid calcium-zinc compound stabilizer
The main components of non-toxic liquid calcium and zinc stabilizers are calcium stearate, calcium ricinoleate, zinc stearate, zinc ricinoleate, and epoxidized soybean oil, UV absorbers, etc. Liquid calcium and zinc stabilizers are generally used in organic solvents more easily soluble fatty acid calcium and zinc salts with a low carbon number. It is a non-toxic stabilizer for PVC and is mainly used as a stabilizer for food packaging films and utensil foam artificial leather.
c. Liquid barium-cadmium and liquid barium-cadmium-zinc compound stabilizers, these compound stabilizers are mainly used in the processing of soft PVC products.
d. Lead salt compound stabilizer heat stability is good, has been widely used, but the lead salt powder fine, ingredients and mixing, its dust by human inhalation will cause lead poisoning, for this reason, scientists and researchers have developed a new compound lead salt heat stabilizer.
The safety of Pvc Heat Stabilizer has received more and more attention, and the safety of Pvc Heat Stabilizer should be considered from three aspects, one is the safety of the processors who use the raw materials, the second is the safety protection of the users, and the third is the safety of the waste to the environment.
The safety of the processors can be addressed through the liquefaction, paste and granulation of the Pvc Stabiliser. For the safety of the user, the Pvc Stabiliser can be polymerised or reactive stabilisers can be prepared to improve its resistance to extraction, but given that stabilisation is a chemical reaction at the molecular level, these methods are not the most appropriate and the best method is to use a high safety Pvc Stabiliser.
When choosing a Pvc Stabiliser, the safety of the chemicals produced by the reaction between the resin and the stabiliser, or between the stabilisers, must also be considered.
Shandong Loyal Chemical Co., Ltd. as a professional Pvc Heat Stabilizer, not only has a high quality product, but also a good price for Pvc Stabilizer.
Pvc Heat Stabilizer delays or avoids heat-induced damage and further degradation of plastics.
Without specifying it, heat stabilisers refer specifically to the stabilisers used in the processing of PVC and vinyl chloride copolymers, i.e. Pvc Heat Stabilizer.
PVC and vinyl chloride copolymers are heat-sensitive resins that are susceptible to the release of hydrogen chloride during heat processing, which can lead to thermal ageing and degradation reactions. Widely used heat stabilizers in industry include salt-based lead salts, metal soaps, organotins, organic antimony and other primary stabilizers and epoxy compounds, phosphite esters, polyols, diketones and other organic auxiliary stabilizers.
Pvc Pipe Stabilizers have the ability to absorb and neutralise HCL and inhibit its autocatalytic effect.
These Pvc Stabilizers include lead salts, organic acid metal soaps, organic tin compounds, epoxy compounds, phenol salts and metal thiol salts. They can react with HCL and inhibit the reaction of PVC to remove HCL. For example, organotin stabilizers are used in coordination with the unstable chlorine atoms of PVC molecules, in which the organotin is replaced with the unstable chlorine atoms.
Pvc Pipe Stabilizer reacts with the polyene structure in an addition reaction, destroying the formation of a large conjugate system and reducing colouration. The salts or esters of unsaturated acids contain double bonds and undergo a double-alkene addition reaction with the conjugated double bonds in the PVC molecule, thus destroying the conjugated structure, inhibiting discolouration, trapping free radicals and preventing oxidation reactions.
