Application:
It is a highly efffective external lubricant for PVC.It is also ideal for pigment concentrates used in coloration of polyolefins.As a
SPE WAX,it is fully compatible with low and high density polyethylene and also good compatibility with polyporpylene.
GS-11 as a low density,medium molecular was has high oxidation resistance and improves the surface finish of products.It is ideal for pigment and additive concentrates for PVC.
GS-13 also acts as a lubricant and tac regular for rubber.As,it is very compatible with rubber;it may be superior to other waxes.
Recommended Dosage:
Depending on the application,it may vary from 0.1-1.0 phr in PVC and from 1.0-6.0 parts in rubber.
