Introduction to PVC Compound

PVC Compound is a pre-mixed plastic composite material, which is made of PVC resin combined with various additives according to a specific formula. These additives may include plasticizers, stabilizers, fillers, lubricants, pigments, etc. PVC Compound is a finished formula that can be directly processed into final products without the need for further mixing with other materials.

Types of PVC Compound

• Rigid PVC Compound: Used for manufacturing pipes, and window profiles, etc.
• Flexible PVC Compound: Applied in cable sheathing, flooring, etc.
• Semi-rigid PVC Compound: A blend between rigid and flexible and is used for specialized applications.

 

PVC Compound Process

The manufacturing process of PVC Compound usually includes the following steps:

 

1. Raw material mixing and melting steps

The primary plastic powder is mixed with other additives in specified proportions. Usually, 85-95% plastic powder, 0.1-10% light diffusion powder, and 2-14.5% anti-blue light powder are blended evenly using a mixer and then heated to a certain temperature to ensure the materials are fully mixed and plasticized.

 

2. Cooling and Solidification step

The fully or partially melted plastic mixture is extruded into the desired shape through a screw. The extrudate is then cooled to a solidification temperature using water or air cooling methods, such as blowers, to solidify it into a dry solid form.

 

3. Pelletizing Process steps

The solidified plastic strands are cut using a pelletizer, precisely trimmed to the required pellet size depending on their intended use. The final product appears as blocks or granules, completing the PVC Compound manufacturing process.

Comparison of PVC Compound and Masterbatch

Composition

• PVC Compound: Contains base PVC resin and all necessary additives, a complete formula.
• Masterbatch: Typically contains a high concentration of pigments or functional additives and needs to be mixed with the base resin during use. Primarily used to provide color or specific functions.

 

Usage

• PVC Compound: Ready for directly for molding processing without additional mixing steps. Ideal for situations where quick production or the absence of mixing equipment is needed.
• Masterbatch: Requires blending with base resin in a specific ratio before use. This process requires an additional mixing step during production but allows for more precise control over the formulation.

 

Concentration

• PVC Compound: Lower concentration of additives, typically between 10-40%, suitable for direct processing without further dilution.
• Masterbatch: High additive concentration, ranging from 20-80%. The high concentration means less material is needed, saving on transportation and storage costs, but requires precise mixing with the base resin.

 

Flexibility

• PVC Compound: Fixed formula, low flexibility. Each Compound has specific properties and colors, and changing the formulation requires reordering a different recipe.
• Masterbatch: Allows for the adjustment of additive ratios according to needs, offering higher flexibility. This is suitable for production scenarios where product characteristics need to be frequently changed.

How to choose: PVC Compound or Masterbatch?

The choice between PVC Compound and Masterbatch depends on various factors, including your specific needs, production scale, technical capabilities, and cost considerations. Here’s a detailed guide to help you decide:

 

When choosing PVC Compound

1. Direct Usage requirements: If you need a material ready for immediate molding and processing, PVC Compound is ideal. It contains all the necessary additives, requiring no additional mixing.
2. Large-Scale Production: For large-scale production, using PVC Compound can simplifies the production process and increases efficiency.
3. High stability requirements: If your product has strict performance stability, pre-formulated PVC Compound can provide more consistent quality.
4. Limited Expertise: If your team has limited experience with recipe adjustments, using ready-made PVC Compound reduces the risk of errors. APEX offers a professional R&D team that can customize PVC Compound according to your needs.
5. Special Performance Requirements: Some specific performance (e.g., high flame resistance, high weatherability) PVC products may require complex formulations, making it more appropriate to choose professionally formulated PVC Compound.

 

When choosing Masterbatch

1. Flexibility Requirement: If you frequently need to adjust the color or functional properties of your products, Masterbatch provides greater flexibility.
2. Inventory Management: Using Masterbatch can reduce the number of SKUs stock as you can manufacture a variety of products using the same base resin with different Masterbatches.
3. Cost-effectiveness: For small batches or multi-variety production, using Masterbatch may be more cost-effective because you can adjust the addition ratio according to your needs.
4. Customized Requirements: If your customers often request specific colors or functions, using Masterbatch can respond to these requirements more quickly.
5. Strong Technical Capability: If your team has expertise in blending and mixing, using Masterbatch can give you more control and achieve more precise performance adjustments.
6. Space Saving: Masterbatch is usually more concentrated than PVC Compound, saving storage space.

 

Comprehensive Considerations

• Product type: Some products may be better suited to PVC Compound (such as medical supplies requiring high consistency), while others may be better for Masterbatch (such as consumer goods with frequently changing colors).
• Production Equipment: Make sure your equipment can effectively handle the materials you choose. Using Masterbatch may require additional mixing equipment.
• Quality Control: Consider your quality control capabilities. Using PVC Compound may be easier to maintain consistent quality, while using Masterbatch requires more rigorous process control.
• Environmental Factors: In some cases, using Masterbatch may be more environmentally friendly because it reduces material waste.
• Supply Chain Considerations: Evaluate the reliability and lead time of suppliers. Sometimes, choices may be influenced by supply chain factors.

FAQ

Q1: How to ensure the quality of PVC Compound products?

To ensure the quality of PVC Compound products, the key is to have a complete quality control system. A high-quality supplier will provide professional in-factory quality control inspection, usually covering four stages: incoming material sampling inspection, in-process quality control inspection, finished product quality inspection, and post-production analytical inspection. These stages enable comprehensive monitoring of the product production process to ensure that the PVC Compound produced meets high standards of quality.

 

Q2: What international standard should a high-quality PVC Compound pass?

A high-quality PVC Compound should pass multiple international standard tests. In addition to in-factory quality inspection, institutional inspection is equally important! This includes testing items to ensure that plastic Masterbatch meets international standards, such as RoHS specifications, eight heavy metal testing, powder inspection, tensile testing, etc., and follows relevant standards such as IEC :, EN71-3, ASTM-F963, etc. These standards ensure the safety and quality of PVC Compound.
