Plastic Grade - SDL Series
Plastic grade SDL series is manufactured with special process. After treatment, the surface has good compatibility with
plastic. It is of porous particle with voids and large specific surface area. With less addition and strong dispersibility, it will not
affect the transparency and strength of plastic film. It is without toxicor pollution, any volatile matter and precipitates are excluded so
that of the packaged is ensured;it can improve transparency of the film, smoothness of surface, anti-adhesion property
of film in the high speed packaging line,with creep resistance and reinforcing effect on the film;it makes exposed molecular
chain of polymer decrease in the processing so that there is no macromolecular chain winding when two films contact.
Therefore the problem of opening is solved; in the meantime, as the molecular chain is not exposed, adsorption capacity is
reduced when the film passes an object so that the smoothness property improves. Furthermore, our company may produce
silicon dioxide with large pore volume (0.25 g/cm3) on the basis of customers requirements.
