Information
CPE is a polymer material obtained by high-density polyethylene (HDPE) by chlorination substitution reaction. The following is a description of CPE.
 
Xiaobian doesn't know how much people know and understand the product. It is not very common in life, but it is widely used in the industry. Then let's take a look at why we should add stabilizers and preservatives to CPE.
 
This is mainly because CPE is a chlorine-containing polymer and has no double bonds on the primary bond of CPE, so CPE has good heat resistance, and the rate of hydrogen chloride removal during production is much slower than that of polyvinyl chloride. In the process of processing, the vulcanization pipe will reach a high temperature of 200 degrees, and hydrogen chloride will continue to be produced in this long-term high temperature environment. Therefore, in order to thoroughly understand the hydrogen chloride, it is necessary to add an absorbent of hydrogen chloride to the production formula. Vulcanization proceeds normally. At the same time, CPE will become aging and decompose under the influence of light, heat and oxygen in the last time, so it is necessary to add stabilizer and preservative in the process of producing CPE.
