Silica gel raw material is one of the most important auxiliary materials for silicone rubber products, and its quality must be ensured first. Therefore, many silicone product manufacturers will require to provide corresponding test reports before purchasing raw materials, and whether they have obtained corresponding requirements. Silica is one of the most important materials in solid silica gel, so its quality determines the performance of the material. Meteorological silica has the main advantage of very fine particle size, Molecular particles have strong adsorption capacity, high chemical purity, good dispersion performance, and fine density, making its thermal resistance, resistance, temperature resistance, and tensile strength stronger than ordinary silicon dioxide. Therefore, it is a high-performance material in high-temperature vulcanized silicone rubber and can meet the requirements of food grade, high transparency, and high tensile strength.

Food grade silicone collagen material:
Vapor silica gel is also the popular choice of food grade silicone collagen materials. It mainly plays a reinforcing role in the raw materials of silica gel. Due to the flexibility of the fine particles of the silicon chain, the purity of the products produced by processing is high, and the handle and tensile life have been improved to a certain extent. The normal life is more than twice that of ordinary precipitation silica gel. At present, FDA can be reached in many markets, The proportion of fumed silica in silica gel products tested and certified by ROHS can reach more than 80%, which can reach the special silica gel material!
