- the present invention relates to hydrogenation It relates to a composition. More specifically, the present invention relates to a hydrogenation composition with improved mouth kneading property that can provide a gasket material with improved prister resistance.
- a cylinder head gasket is a component that stacks rubber on a metal plate to seal between an engine and a block. When using it, water resistance is required because the engine cooling water comes into contact with the gasket, and if water resistance is poor, then pristers are seen.
- Fluthermore as a rubber material, although fluororubber has excellent prister resistance, it has a demerit of high cost.
