Product Description

Amorphous silica with stable chemical properties, non-toxic and harmless, good biocompatibility, excellent dispersibility, high bulk density, good fluidity, narrow particle size distribution, low expansion and friction coefficient. It disperses uniformly in resin materials, forms micro-nano structures on film surfaces, giving smoothness, high transparency, low haze, and excellent anti-blocking performance. High purity, low metal ion content, and excellent anti-yellowing properties in composite materials with polyolefins and polyesters.

Main Technical Indicators & Properties

Applications

Suitable for synthetic fibers, melt-blown fabrics, injection masterbatch, BOPP film, polypropylene, polyethylene, polycarbonate,PVC and other polymer materials. Used as anti-blocking, slip, anti-adhesive, anti-caking, flow aid, dispersant. Composite films with polyolefins/polyesters are suitable for food and pharmaceutical packaging.

Product Features

Ultra-low surface area and oil absorption, Forms rough structures on film surface, reduces contact area between layers, creates micro-gaps, reduces viscosity and friction.
