This product can be used to manufacture products with different hardness and different performance requirements. After vulcanization, within a certain period of time, the surface of product can precipitate silicone oil for self-lubricating. It has good physical properties and processability and is applicable to various silicone rubber connectors, sealing elements and washers requiring self-lubricating property with molding process and is widely used in the machinery industry, automotive industry and aerospace industry.
