Chloropolyethylene (CPE)
Chlorinated polyethylene (CPE) compounds from Mountville Rubber deliver outstanding resistance to heat, oil, ozone, and flame, making them an excellent choice for applications that demand durability in aggressive environments. These compounds are engineered to retain flexibility and strength while providing long-term stability in automotive, industrial, and wire and cable applications. CPE is especially valued for its flame retardancy and weather resistance, ensuring reliable performance in both indoor and outdoor systems.
Available in sheets, slabs, and strips.
