Chlorinated polyethylene (CPE) 135A is a versatile polymer modifier widely used in PVC (polyvinyl chloride) products to enhance their performance. Here are the key roles and benefits of CPE 135A in PVC products:

1. Impact Resistance:

Enhanced Toughness: CPE 135A improves the impact resistance of PVC, making it less brittle and more durable, especially at lower temperatures.

Crack Resistance: It helps PVC products withstand mechanical stress and reduces the likelihood of cracking.

2. Flexibility and Softness:

Increased Flexibility: Adding CPE 135A to PVC enhances its flexibility, making it suitable for applications requiring bending and stretching.

Improved Softness: It also imparts a softer texture to PVC, which can be beneficial for products like hoses, cables, and flexible profiles.

3. Weather Resistance:

UV Stability: CPE 135A improves the UV resistance of PVC, protecting it from degradation due to sunlight exposure.

Ozone Resistance: It also enhances PVC's resistance to ozone, which is important for outdoor applications.

4. Chemical Resistance:

Chemical Stability: CPE 135A improves the chemical resistance of PVC, making it more resistant to various chemicals, oils, and solvents.

Corrosion Resistance: It helps PVC resist corrosion, which is crucial for applications in harsh environments.

5. Flame Retardancy:

Enhanced Fire Resistance: CPE 135A can improve the flame retardancy of PVC products, making them safer for use in applications where fire resistance is important.

6. Processing Advantages:

Ease of Processing: The addition of CPE 135A can improve the processing characteristics of PVC, making it easier to extrude, mold, and form into various shapes.

Compatibility: CPE 135A is compatible with PVC, allowing for smooth blending and uniform dispersion within the PVC matrix.

7. Applications:

Pipes and Fittings: Enhanced impact resistance and weatherability make CPE 135A-modified PVC ideal for pipes and fittings.

Profiles and Sheets: Flexibility and durability are beneficial for profiles, window frames, and sheets.

Cables and Wires: Improved flexibility and fire resistance are important for electrical cables and wires.

Hoses and Tubing: Chemical and weather resistance are crucial for hoses and tubing used in industrial and agricultural applications.

In summary, CPE 135A is a valuable additive in PVC products, enhancing their mechanical properties, weather resistance, chemical stability, and processing characteristics, making them suitable for a wide range of applications.
