PVC Impact Modifier CPE Series

Composition: Chlorinated polyethylene (CPE) is produced by chlorinating high - density polyethylene (HDPE), which is a product of partially replacing hydrogen atoms on the HDPE molecular chain with chlorine atoms. Its molecular formula is (CH₂ - CHCl - CH₂ - CH₂)ₙ.

Appearance: It is a white powder, non - toxic and odorless.

Packaging: Usually packed in 25 - kg bags or 500 - kg bulk bags.

Storage: It should be stored in a cool, dry, and ventilated place, protected from sunlight and rain, and away from fire and heat sources.

Transportation: During transportation, it should be prevented from being damaged, wetted, and contaminated. It should be transported according to general chemical regulations.

product details

Properties

Excellent impact resistance: It can significantly improve the impact strength of PVC products at low temperatures. For example, CPE - 135A has outstanding low - temperature impact performance.

Good weather resistance: Since the CPE molecule does not contain double bonds, it has good weather resistance, and its heat - resistance, flame - resistance, and ozone - resistance are also excellent.

Good compatibility: CPE with a chlorine content of 36% - 38% has good elasticity and compatibility with PVC, and can form a three - dimensional network structure inside PVC products under the correct processing conditions.

Good processability: It can delay the plasticization of PVC when the addition amount is low, and promote plasticization when the addition amount is high. It also has a certain lubrication effect, which can improve the processing performance of PVC.
