Timing Belts(HNBR)

Automotive timing belts characteristics

▶ CR:

❶ Good ageing resistance (especially ozone resistance): Neoprene belt can be used for a long time in a working environment of 110°C and below;

❷ Good chemical stability: in addition to strong oxidizing acids, it is resistant to general chemicals;

❸ Good fire and waterproof performance

▶ HNBR:

❶ Extremely low oil swelling degree；

❷ oil resistance&durability；

❸ dynamic wear resistance

▶ HNBR vs. CR:

The timing belt made of hydrogenated nitrile rubber can work at -40℃～+150℃. Its durability is increased by more than 1.5 times, the bandwidth is reduced by 20%, and the heat resistance is increased by 10°C. Therefore, in terms of fatigue life and water resistance, it is better than timing belts made of chloroprene rubber and chlorosulfonated polyethylene.
