EDPM

EPDM exhibits satisfactory compatibility with fireproof hydraulic fluids ketones, hot and cold water, and alkalis and exhibits unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents and concentrated acids.

The main properties of EPDM are its outstanding heat, ozone, and weather resistance. The resistance to cold substances and hot vapor are also good. It has excellent electrical insulating properties. It has good resistance to ketones, ordinary diluted acids, and alkalies.

Description

EPDM –(Ethylene Propylene Diene Monomer) is a synthetic rubber, highly flexible stable material that is not only easy to work with, but long lasting and aquatic safe:  fire fighting water, rainwater waste water etc., and liquid storage. Flexible, robust material with excellent wear, damage resistance and durability; 100% UV protection. Quick and easy installation, easy to repair.  Material retains its properties -40°C to +40°C.

Lifetime 15+ years
