Polyphenylmethyl dimethicone is widely used in self-lubricating liquid silicone rubber, enhancing the lubrication properties of the silicone rubber and improving its separation performance. It also helps reduce surface defects such as adhesion, cracking, or roughness, resulting in a smoother and more aesthetically pleasing product surface. It plays a key role in improving the performance and quality of self-lubricating liquid silicone rubber, providing excellent lubricity, separation, surface quality, temperature stability, chemical inertness, and durability.
