Plasthall® P 670 the best combination of heat, aging and fuel resistance in Chlorinated Polyethylene Elastomers (CPE)

Polymer information

Chlorinated Polyethylene elastomers(CPE)are produced from HDPE that is randomly chlorinated in an aqueous slurry. Polymers are differentiated by chlorine content, molecular weight and crystallinity. Chlorine contents generally range from 25 to 42 percent. Advantages of using CPE include very good resistance to ozone, oxidation, abrasion and flex cracking. CPE also has good resistance to alcohols, alkalis and acids. Limitations for CPE include moderate resistance to aromatic oxygenated solvents.

Because of its unsaturation, CPE is usually peroxide –cured and some plasticizers may affect cure rate and degree of cure. Plasticizer containing double bonds (oleates and tallates) can rob curative effectiveness, as can naphtenic oils. Generally, polymeric plasticizers do not provide significant performance advantages over monomerics and are seldom used.
