Product Description

Product Description

Nanometer silica, commonly known as "ultrafine white carbon black", is widely used in various industries as an additive, catalyst carrier, petrochemical, decolorizing agent, matting agent, rubber reinforcing agent, plastic filler, ink thickener, metal soft polishing agent, insulating and thermal insulation filler, high-grade daily cosmetic filler and spraying material, medicine, environmental protection and other fields. And it provides a new material basis and technical guarantee for the development of related industrial fields.

The molecular formula of fumed silica is SiO2. It is a white fluffy powder, porous, non-toxic, odorless, pollution-free and heat-resistant. At the same time, its chemical inertness and special thixotropic properties significantly improve the tensile strength, tear resistance and wear resistance of rubber products. The strength of rubber is increased by tens of times after improvement. Rheological and thixotropic control of liquid systems, adhesives, polymers, etc., as an additive for anti-settling, thickening and anti-sagging, reinforcement of HCR and RTV-2K silicone rubber, can be used to regulate free flow and as an anti-caking agent to improve powder properties, etc. CASNO:112 945-52-5

Application

1.Reinforcing: Improve the tensile strength, tear strength, toughness and impact resistance of the product;
2.Thickening, improving the product consistency of liquid system, rheological control, thickening without thinning;
3.Thixotropy, one touch change, improve the rheological and thixotropy of liquid systems;
4.Anti caking, promote and maintain the fluidity and anti caking performance of powder particles;
5.Anti sagging: prevent the liquid from flowing and sagging, and improve the flatness of the construction surface;
6.Anti sedimentation improves the adhesion of various systems, effectively prevents layered sedimentation, and is an ideal suspending agent; Thermal insulation: thermal conductivity and excellent thermal insulation effect;
