• Schematic diagram of the state of slip agent in the film

Amide or low molecular weight polysiloxane, migrate on the surface of the film  

Ultra-high molecular weight polysiloxane tends to migrate to the surface layer, but the molecular chain is too long to be completely precipitated, forming a silicon-containing lubricating layer on the surface  

Copolymerized polysiloxane, the long carbon chain active functional group can produce physical or chemical bonding with the matrix resin, which is equivalent to the role of rivets, and the siloxane chain segment is on the surface layer, which plays a smooth role
