1. The characteristics of the two products are different:
1. The characteristics of the silica gel gasket: it has certain tension, flexibility, excellent insulation, pressure resistance, high temperature resistance, low temperature resistance, stable chemical properties, environmental protection and safety, and no odor. The food-grade silica gel gasket is nontoxic and tasteless, insoluble in water and any solvent, and is a high-activity green product.
2. Characteristics of PTFE gasket: This material product has the characteristics of acid and alkali resistance, high temperature resistance and resistance to various organic solvents.
2. The uses of the two are different:
1. The uses of silicone gaskets: they are widely used in plexiglass, glass crafts, display racks, household appliances, furniture products, hardware accessories, transparent plastic products, etc.
2. Use of PTFE gasket: It is widely used in chemical and pharmaceutical industries. It is widely used in petroleum, chemical, pharmaceutical, electric power and steel industries. Suitable media include water, oil, acid solution, alkali solution and almost all chemical components.
Third, the functions of the two are different:
1. The function of the silicone gasket: the transparent silicone gasket has beautiful appearance, shockproof, anti-skid, anti-collision and scratch-proof functions, and the transparency is extremely high.
2. The function of PTFE gasket: it has good mechanical toughness; Even if the temperature drops to -196℃, the elongation of 5% can be maintained. For most chemicals and solvents, it is inert, resistant to strong acid and alkali, aqua regia and various organic solvents.
