Nitrile rubber has very good oil resistance, basically does not swell to non-polar and weakly polar oils, but has poor resistance to aromatic hydrocarbons and chlorinated hydrocarbon oils.
Chemical resistance is better than natural rubber, but its resistance to strong oxidizing acids is poor.
The abrasion resistance is 30%-45% higher than that of natural rubber.
When this Bellow is used on the roller structure of the marble cutting machine, it needs to reciprocate, and it will be in contact with a certain amount of oil. It also needs to be dustproof, so nitrile rubber is finally used.
If you need to customize your rubber parts, you could kindly offer the inormation as below, we could make the quotation based on that.
