Product Description:

Product name: Powder silica (SiO2)

Properties: with stable physical and chemical properties, non-toxic, high adsorption, low specific gravity, easy to flow and high specific surface area and other excellent properties, so widely used.

Appearance: white powder.

Purpose:

1. This product is a good carrier of various veterinary drugs, feed flavoring agents, allicin, mildew prevention agents, acid flavor agents, antioxidants, etc., with a very good dispersion, fluidity and adsorption.

2. The product is a very good rubber tonic agent, it can greatly improve the tensile strength of the vulcanized rubber and wear resistance, reduce the amount of rubber, reduce the cost, with strong affinity, make it in the rubber has greater dispersion ability, carbon black particles and rubber molecules form physics, in enhancing the sulfide rubber mechanical strength and tear reinforcement is better than carbon black.

Storage conditions: dry storage, pay attention to moisture-proof.
