CPE — Chlorinated Polyethylene
Impact Modifiers & Flexibility Enhancers
CPE — Chlorinated Polyethylene.
CPE is a chlorinated polyethylene modifier specifically formulated to enhance the flexibility and impact resistance of rigid PVC products. Its solubility parameters closely match those of PVC, giving it excellent affinity and compatibility. Under correct processing conditions, CPE 135A forms a network structure within the hard PVC matrix, delivering outstanding normal and low-temperature flexibility and impact strength. Coated with 5–15% active CaCO₃ under standard conditions.
