Silica gel is relative to solid high temperature vulcanized silicone rubber, which is a solid rubber. It has good activity, fast vulcanization, safety and environmental protection, and can fully meet the requirements of food grade. Liquid silica gel in technology and production process and solid silica gel is a certain difference, liquid silica gel is different from the characteristics,
1, liquid silica gel raw materials are low viscosity, good activity, injection molding, easy to operate;
2, liquid silica gel curing product shrinkage rate is low, less than 0.1%, has the advantages of good water resistance and moisture resistance, in -60 degrees Celsius to 500 degrees Celsius to maintain good elasticity: and solid glue as raw material products can be up to 1200 degrees Celsius, brittle, poor elasticity;
3, liquid silica gel preservation is good, without adding curing agent (at room temperature 25 degrees Celsius sealed from moisture, not in high temperature) can be placed for at least 1 years without deterioration;
4, liquid silica gel has good chemical resistance, acid and alkali resistance, weather resistance and a variety of chemicals; 5, good mechanical strength, excellent high temperature compressor can be deployed according to customer needs of different strength of products;
5, excellent electrical insulation, excellent dielectric function, excellent dielectric function at high temperature, dielectric property greatly exceeds organic rubber at high temperature;
6, excellent high and low temperature resistance function, curing molding permanent deformation; High tensile and tear strength, more times of mold turning, can be used repeatedly.
8, is not limited by the thickness of products, can be at room temperature can also be heated curing molding, environmental protection, non-toxic no gas. Many applications of silica gel in life are gradually found by people, replacing more materials in our daily life.
