With the continuous improvement of people’s living standards, the plastics industry is also developing continuously. The market has put forward higher requirements for the performance of plastic products. The plastic processing industry prefers to use various convenient functional masterbatches to reduce raw material and processing costs and improve production efficiency. It can enhance the different properties of plastic products. This in turn meets diverse market needs.
You can find more information on our web, so please take a look.
Functional masterbatch refers to concentrated forms of various plastic additives. They are difficult to disperse directly. Inefficient if added as is. Therefore they are usually introduced in the form of masterbatch.
Introduction to Several Common Types of Functional Masterbatch:
1. Cooling Masterbatch
Primarily used for PP, it can reduce temperatures by approximately 30-50 degrees.
2. Filler Masterbatch
Besides calcium carbonate, fillers used in plastic products include talcum powder, silica, graphite, kaolin, mica, and other inorganic mineral materials. These fillers find widespread use in PE, PP, PS, ABS, and other plastic products.
3. Foaming Masterbatch
Utilizes heat-absorbing closed-cell chemical nucleating agents, suitable for foam injection molding of thermoplastic plastics like PP, ABS, PS, PE.
4. Moisture Absorption and Defoaming Masterbatch
Mainly used to remove moisture and unknown low-molecular-weight volatiles from plastics. Products are free of splashes and bubbles. Thus product quality is guaranteed while reducing the drying process.

5. Antistatic Masterbatch
Composed of carriers and antistatic systems, it is used to lower the surface resistance of materials. It can prevent the adverse effects of static electricity on various industrial sectors and humans.
6. Antibacterial Masterbatch
Comprising a certain amount of antibacterial masterbatch mixed with corresponding resin particles, it can be used to manufacture plastic products and fibers with antibacterial effects (bactericidal and bacteriostatic).
7. Reinforcement Masterbatch
Enhances the strength of target materials. Modified materials can be widely used in manufacturing industries such as construction, machinery, electronics, appliances, automotive, transportation, daily necessities, and agriculture.
8. Brightening Masterbatch
Also known as a brightening agent, it aims to increase the brightness of products. The brightening agent is mainly ethylene bis-ceramide, with masterbatch usage typically ranging from 20% to 30% and product inclusion from 0.2% to 0.3%. Excessive use can affect printing results.
9. Flame Retardant Masterbatch
Mainly used for flame retardant modification, composed of flame retardant resin additives.
10. Weather-Resistant Masterbatch
Composed of light stabilizer resin additives.
In conclusion, functional masterbatches play a crucial role in meeting the ever-growing demands for improved plastic product performance. These masterbatches provide a versatile and convenient solution for the plastic processing industry. It contributes to cost reduction and increased efficiency. The production of high-quality plastic products that cater to diverse market requirements.
I am curious about how to the use master batch function. If someone could walk me through I would appreciate it. I see that the total of the 'liquid required' and the 'master batch lye weight' numbers change. Any information and help would be helpful to me. Thanks so much!
Thank you all so much for your responses. I have taken a screen shot of a recipe. The master batch function is on and set to 1:1. (I usually use a 1.75:1 ratio. but for ease I used a 2:1 ratio). When I look at the formula, I don't understand how there is so much lye. Do I have to subtract the 'liquid required' from the 'master batch lye weight' and what's left would be the extra liquid I would need to bring my lye water to 2:1? It's confusing to me. It seems like it should give a separate lye weight like it does when the 'master batch' function is turned off. Walk me through please
hi,
from my understanding, i use master batch function when I have made a 50/50 lye solution, then the masterbatch lye weight is the amount of the solution that I will measure for the soap. then the liquid required is the additional amount of water/milk that I will add to reach the lye concentration I want like 33.33% or 40% lye concentration
Masterbatch means you mix all of your water and lye in advance, and keep it on hand. (I put mine in a big old detergent jug with huge unmistakeable labels of danger! lye! all over it). That way, the lye/water is premixed and at room temperature whenever I want to make soap. In the past I did a 50/50 (which is 1:1 in the calculator, equal parts water and lye).
When I make soap, I generally need more liquid in the recipe than that master batch. So I recently started 2:1 water:lye so I never need to add more liquid if using water since my recipes all are 2:1.
Anyway, your recipe then will show you the amount of your masterbatched water:lye mixture as well as any additional liquid you may need for the recipe you are using at that time.
When I masterbatched; Here is how I used it with my original recipe. Say, your recipe calls for 7 oz of lye and 14 oz of distilled water. I used 7 oz of lye and 7 oz of distilled water. And the other 7 oz liquid that was left over, I added it to the oil before the lye/water was added. I used either 7 oz of coconut milk or 7 oz of Goat milk or 7 oz of distilled water, or 7 oz of aloe vera juice.
When you are making soap, lets say your recipe calls for 10 oz. of lye - grab your container, again make sure it is well mixed, and measure out 20 oz.(50/50 mix = 10 oz. lye and 10 oz. water.) Now lets say that your recipe is calling for 20 oz. of water, add 10 more ounces of distilled water to your mix. (If you were going to use 5 oz of another liquid, use that as part of your 10 oz.) Now you can add this mixed liquid to your oils and bring to trace.
