Product Description

Silica for functional masterbatches  
Features and Advantages:
Plastic masterbatch is made of silica by special process, widely used in plastic opening agent masterbatch and functional masterbatch, plastic and PP (polyethylene), PVC (polyvinyl chloride), mostly used in PP masterbatch. It can also be used as EVA opening agent. The gel silica ratio, good transparency, easy to disperse, easy to add, when the production of high transparent film can be selected as the gel silica filling material. If the transparency of the product is not high, you can choose the precipitation method of ultrafine silica.
