According to different structures and uses, chlorinated polyethylene can be divided into two categories: resin-type chlorinated polyethylene (CPE) and elastomeric chlorinated polyethylene (CM). After chlorination is completed, the whole system is acidic, and part of dilute hydrochloric acid will remain on the surface of chlorinated polyethylene. In order not to affect the product quality, deacidification work needs to be carried out.
