â—†Features:
1. Friction: The effect of static/dynamic friction reduction is obvious, which is superior to other competitive grades, which can reduce the addition amount of amide slip agent.
2. The porous structure of the silica opener can effectively improve the phenomenon of "end yellowing". The porous structure of silica adsorbs metal ions, such as iron ions, and the possibility of oxidation causes yellowing.
3. The silica opener has a large bulk density, is easier to mix with the resin, and is more convenient for processing operations.
4. The use of highly transparent profiles for silica openers has a very small effect on film transparency and haze rise.
