PVC processing aids (PA-920 Series)
Description:
It can significantly promote plasticizing PVC mixture, while improving the melt fluidity, in order to obtain a good product plasticized at a temperature as low as possible to improve the surface gloss of the article.
Advantages:
·Outstanding performance plasticizing
·Reduce energy consumption during processing
·Good dispersion
