Product Description

Product Description

Precipitated Silica

This high-performance synthetic silica is produced through an advanced wet precipitation process, yielding a porous, high-surface-area material with tunable particle size. Its unique properties make it ideal for enhancing rubber products (like tires and shoe soles), acting as a matting agent in coatings and a mild abrasive in toothpaste, improving powder flow in food/feed applications, and serving as a pesticide carrier in agriculture. Manufactured sustainably with low energy consumption, it delivers versatile functionality across industries.

Application

It can be used as a reinforcing filler for the production of green tires, and can replace carbon black for the tire side, which can significantly increase the tear strength and tear growth resistance of the tire side, and has no obvious effect on the vulcanization time. Ozone aging resistance depends on the amount of antioxidants and white carbon black. Adding white carbon black to the tread can improve the anti-cutting and anti-tearing properties of the tread and reduce the flaking block. The rolling resistance of silica filled compound can be reduced by 30% compared with that of ordinary carbon black filled compound.

Our precipitated silica offers excellent dispersibility for uniform blending, along with superior reinforcing and thickening properties to enhance product strength and viscosity. It provides reliable anti-settling and anti-sagging performance for stable suspensions in coatings, adhesives, and sealants. With efficient thickening capabilities, it improves texture while maintaining flowability. Ideal for rubber, coatings, and specialty chemicals, it ensures consistent quality and processability. Sustainable production makes it an eco-friendly choice for diverse industrial applications.
