B908 Plastic Slip agent

Slip Agent 1. Gasoloid silica dioxide slip agent, its main content is SiO2, average particle size arrangement is narrow, and surface area is big, high whiteness, no poisonous, no smelly, high transparent powder, they can be the slip agent in the polyethylene, polypropylene, PVC, ethylene-propylene copolymer, and polyester. 2.Anti-blocking agent machanism: Before turing into the film, it need add the SiO2 substance. In the concave and protruding layer on the film surface, it can stop the low molecular weight substance effusion and enlace, making it has the anti-blocking effect. It can show thinner and wider effection than the oleic acid alanyl, and more enviroment,more weatherable. Why do we use the Silica dioxide slip agent? After the polyethylene blow into film, because the film can be vacuum and close , not easy to separate, this time you need add it.
