Due to the rapid development of auto industry, auto parts for automotive rubber seal and other accessories material has a higher request, therefore hydrogenated nitrile rubber seals
used in automobile industry is also more and more.
seals have stringent requirements in car use, such as heat resistant, oil resistant, resistant to all kinds of performance and flame retardant properties such as chemical corrosion, etc.
Nitrile rubber seal can only be used under 120 ℃, and ozone resistance, weather resistance and radiation resistance can't satisfy the automobile engine sealing requirements;
Fluorine rubber seal is expensive, manufacturability is poorer, acrylate rubber seals, though high heat resistance, but the process performance is poor.
Hydrogenated nitrile rubber seals seals have good cost performance and machining performance, and its heat resistance can meet the new needs, so the hydrogenated nitrile rubber seal is not only used in the automotive industry, are widely used in other industries.
First automobile synchronous cog belt material use NBR NBR, due to its dynamic performance and ozone resistance is poorer, product life is very short, so use nitrile rubber, neoprene instead of ozone resistance improved.
But hydrogenated nitrile rubber is better than neoprene heat resistance, working temperature can be improved about 30 ℃, hydrogenated nitrile rubber has high strength, high wear resistance, ozone resistance, due to its dynamic elasticity with the temperature change is small, power can be maintained in a large temperature range accurate transmission, is the ideal rubber seals synchronous cog belt.
Different car parts condition is different, is different to the requirement of rubber seals, so choose what kind of material still need to work, if you want to know more about the performance of the rubber seals, consulting, 18 years seals manufacturer!
