Rubber

The characteristics of the polymer

EPDM

Good resistant against weather, organic phosphate hydraulic oil, acid base,
hot water, vapor, brake oil, soap base liquid, Sulfur Hexafluoride.

NBR

Good resistant against mineral oil, plant oil, fat, alkali and alcohol.

PTFE

Good sealing performance, good resistant against abrasion and weather, non
sticky. Anti-chemical corrosion, surface gloss, no poison, mostly be applied into food and drink field with harsh working condition and big difference in temperature and called as “super gasket”

FKM

Good resistant against high temperature, better anti-chemical corrosion performance than NBR. Good resistant against the oil products, chlorides solvent and aliphatic hydrocarbon, aromatic hydrocarbon as well as other strong and flammable liquid. The price is higher than other types.
