Introduction to chlorinated polyethylene

1) CPE is a saturated rubber, which has excellent resistance to heat and oxygen aging, ozone aging, acid and alkali resistance, and chemicals.

2) CPE has excellent oil resistance. Among them, it has excellent resistance to ASTM No. 1 oil and ASTM No. 2 oil, which is equivalent to NBR; and it has excellent resistance to ASTM No. 3 oil, which is better than CR and is equivalent to CSM.

3) CPE contains chlorine element, has excellent flame retardant properties, and has the characteristics of burning and dripping. It can be combined with antimony flame retardant, chlorinated paraffin, and Al(OH)3 in an appropriate ratio to obtain a flame retardant material with excellent flame retardancy and low cost.

4) CPE is non-toxic, does not contain heavy metals and PAHS, and it fully meets environmental protection requirements.

5) CPE has high filling performance and can produce products that meet various performance requirements. The processing performance of CPE is good, and the Mooney viscosity (ML121 1 4) is available in a variety of grades between 50-100.

The main purpose

At the end of the 1990s, the domestic demand for high-performance flame-retardant rubber increased, especially the development of the wire and cable industry and auto parts manufacturing industry, which drove the consumer demand for rubber-based CPE. Rubber CPE is a special synthetic rubber with excellent comprehensive performance, heat-resistant oxygen ozone aging, and good flame retardancy. Mainly used in: wire and cable (cables for coal mines, wires specified in UL and VDE standards), hydraulic hoses, automotive hoses, tapes, rubber sheets, PVC profile pipe modification, magnetic materials, ABS modification, etc.
