Liquid silicone is a non-toxic, heat-resistant, highly resilient flexible thermoset material, and its rheological behavior is mainly manifested as low viscosity, rapid curing, shear thinning and high coefficient of thermal expansion. Its products are characterized by good thermal stability, cold resistance, excellent electrical insulation properties, and will not produce toxic substances when burning; Therefore, it has become an irreplaceable material in the production design of health products, automobiles, silicone bottles, medical supplies, diving supplies, silicone kitchen utensils and silicone pads.
