Saturated polymer backbones rubber


ethylene propylene diene monomer rubber
EPDM is compatible with polar substances, e.g. fireproof hydraulic fluids, ketones, hot and cold water, and alkalis. It is incompatible with most hydrocarbons, such as oils, kerosene, aromatic, gasoline, as well as halogenated solvents. EPDM exhibits outstanding resistance to heat, ozone, steam and weather. It is an electrical insulator.


It is common in vehicles like door seals, window seals and trunk seals.


Heat, Ozone & UV Resistance

Due to these characteristics, it suits for outdoor using

Waterproof & Steam Resistance

For these specifications, it can be use to cover roof
