Difference between Chlorinated Polyethylene (CPE) and ACR and their Applications

CPE and ACR are two essential materials for manufacturing most of rigid PVC (UPVC) products. Their application in the production of PVC products are as below:-

CPE 135A is a kind of low-price impact modifier used in UPVC production, while ACR is used to promote the platicization in UPVC production.

CPE is the abbreviation of chlorinated polyethylene, which is chlorinated from high density polyethylene. The appearance is white powder.

CPE’s Properties

1、Excellent ageing resistance;

2、Excellent flame retardancy;

3、High flexibility under very low temperature;

4、Excellent chemical resistance and ozone resistance;

5、Good processibility;

6、High stability.

Main applications of CPE

CPE has double performance of plastic and rubber. It can be compatible with plastics and rubber well. Except small amount of CPE used as main material, most of CPE is used as additive in plastic and rubber industry. CPE is mainly used as impact modifier of rigid PVC products and it can improve impact performance under low temperature condition. CPE is used to produce UPVC profile, pipe and injected products. CPE is used to enhance the flame retardancy, insulation and ageing resistance of rubber.

ACR is recognized as an ideal UPVC processing aid agent and it can be added into all rigid PVC products.

Application:

1. UPVC profile;

2. UPVC pipe and pipe fitting;

3. UPVC board;

4. PVC buckle plate.

Properties:

1. Good dispersibility in PVC resin;

2. Good fusion strength;

3. Excellent surface brightening;

4. Deduction of plasticizing time.
