Product Description
Pvc Processing Aid Cpe 135a Chemical Impact Additive With Good Low-Temperature Flexibility And Better Tearing Strength
Product Description
The product is no rules structure of the saturated thermoplastic resin, its appearance is white powder; it can be mixed and used with PVC, evidently increasing the impact resistance strength in lower temperature, flame resistance, ageing resistance and flexure performance.
Examples of Application:
CPE 135A is designed for general purpose plastic impact modification where superior impact strength, good low temperature property and high filler acceptance are required. This grade is the most popular grade for plastic impact modification. The application fields cover PVC door and window profiles, siding, sheet, fence, pipe, electrical conduit etc.
Product performance:
It is white powder and innocuous. Since hydrogen atoms are replaced by chlorine atoms, the crystallization of HDPE was destroyed and becomes soft and full of rubber property. Because of the presence of chlorine atom, CPE turns into polar polymers and has the same polar groups as PVC. Under this situation, it increases the compatibility of PVC. In addition, it can blend with PE, PS and rubber to improve its physical properties.
Features:
It may also be described by the following terms: Good Flow, Good Chemical Resistance, Chemical Resistant, High Molecular Weight, High MW, Low Taste, Good Processability, Easy Processing, Low Temperature Resistant, Low Temperature Performance, High Heat Resistance, Heat Resistant, Good Weather Resistance, Weather Resistant, Good Weatherability, Good Flexibility, Flexible, Low Temperature Flexibility.
