White Powdered PVC Processing Aid CPE 135A - 34% Chlorine Content, 1.21 g/ml Density for Enhanced Impact Resistance
White Powdered PVC Processing Aid CPE 135A is a saturated thermoplastic resin that significantly enhances PVC's impact resistance, flame resistance, and low-temperature performance. This chlorinated polyethylene additive improves compatibility with PVC while maintaining excellent processing characteristics.
CPE 135A is ideal for general-purpose plastic impact modification where superior impact strength, excellent low-temperature properties, and high filler acceptance are required. This grade is widely used in:
- PVC door and window profiles
- Siding and fencing systems
- Sheet materials and piping
- Electrical conduit systems
The replacement of hydrogen atoms with chlorine atoms destroys HDPE crystallization, creating a soft material with rubber-like properties. The presence of chlorine atoms makes CPE compatible with PVC and allows blending with PE, PS, and rubber to enhance physical properties.
- Excellent flow properties and processability
- High chemical resistance and molecular weight
- Superior low-temperature flexibility and performance
- High heat resistance and weather resistance
- Good weatherability and flexibility
- Low taste and easy processing
