SNBR is a terpolymer elastomer of butadiene, styrene and acrylonitrile. It chemically combines the high mechanical strength of SBR with the oil resistance of NBR in the same molecular chain, offering superior performance to conventional physical blends.

Key Features

High mechanical strength – Tensile strength far exceeds that of NBR; outstanding tear resistance
Good oil resistance – Retains NBR's resistance to fuel and mineral oils
Excellent low‑temperature performance – Remains elastic down to -45°C; ideal for cold environments
Low compression set – Long‑term sealing reliability
Abrasion & water resistance – Longer service life under dynamic condition
Processing stability – Single polymer type ensures batch‑to‑batch consistency and simplified production

Typical Applications

Low‑temperature oil‑resistant O‑rings and oil seals
Automotive fuel system seals, engine mounts
Oil‑resistant hoses, conveyor belts, industrial gaskets
Oil‑resistant boots, abrasion‑resistant articles
