Silica gel is relative to solid high temperature vulcanized silicone rubber, which is a solid rubber, with good activity, fast vulcanization, safety and environmental protection, can fully meet the requirements of food grade.
Liquid silicone is different from solid silicone in terms of technology and production process, and liquid silicone is different from the characteristics, the following is a simple explanation with you:
1, liquid silica gel raw materials are low viscosity, good activity, injection molding, easy to operate;
2, liquid silicone solidification product shrinkage is low, less than 0.1%, with good water and moisture resistance, at -60 degrees Celsius to 500 degrees Celsius to maintain good
The elasticity of solid rubber products as raw materials can withstand temperatures of up to 1200 degrees Celsius, easy to crisp, poor elasticity;
3, liquid silica gel preservation is good, without adding curing agent (at room temperature 25 degrees Celsius sealed from moisture, not high temperature) can be placed at least 1 year without deterioration;
4, liquid silicone has good chemical resistance, acid and alkali resistance, weather resistance and a variety of chemicals;
5, good mechanical strength, excellent high temperature compressor performance, can be deployed according to customer needs of different strength products;
6, excellent electrical insulation, excellent dielectric function, excellent dielectric function at high temperature, dielectric property at high temperature is much more than organic rubber;
7, excellent resistance to high and low temperature function, curing molding permanent deformation; High tensile and tear strength, many times over mold, can be used repeatedly.
8, not limited by product thickness, can also be heated at room temperature curing molding, environmental protection, non-toxic no air, can pass the EU RoH, FDA food grade quality requirements.
