Hydrated Precipitated Silica For Food Grade Silicone Rubber
Product:JS-160(96)
CAS. NO.:7631-86-9
Application: Hydrated silica for food grade silicone rubber/silica powder for food grade silicone rubber
JS-160（96）Silicone has excellent electrical insulation, thermal insulation and water repellent properties. It is widely used in food grade silicone rubber products, plastics and rubber materials, adhesives, sealants, coatings, etc., and can improve the performance of food grade silica sols and various synthetic resins.
In terms of application in food grade silica sol products, JS-160（96）Silicone used plays a role in filling, reinforcing, plasticizing, and adjusting the proportion in food grade silicone rubber products. For example, after adding JS-160（96）Silicone, the hardness of the silicone rubber product can be increased, and the tensile resistivity, tear strength and tensile modulus have also been improved. In addition, adding JS-160（96）Silicone in certain proportions can effectively increase the cross-sectional area and reduce the specific gravity. Therefore, when adding JS-160（96）Silicone to food grade silica sol products, a certain amount needs to be added to meet the original requirements, but too much silicone dioxide will also cause adverse effects on the nature and performance of the product.
In the production process of food grade silicone rubber products, JS-160（96）silicone is a key modification material with high purity, large specific gravity and good hydrophobicity. Compared with other substrates, JS-160（96）Silicone can reduce the thermal expansion coefficient, increase the surface hardness and wear resistance, reduce internal stress, improve the nature and performance of food grade silicone rubber products.
