The main purpose
1. Uses: It is suitable for heat transfer printing equipment, large-scale mechanical equipment sealing and other industries. It can be used as heat-resistant baking gaskets for electronic instruments and circuit boards, heat-resistant pads for textile dyeing machines, food baking placemats, automobiles, aerospace, Computers, mechanical and electronic industries, fax machines, high-temperature parts in printers; automotive mechanical bodies, kitchen appliances, home appliances and other equipment, etc.
2. Features: Silicone foamed silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is that it can be used at -60°C (or lower temperature) to +250°C (or higher temperature) for long-term use. However, the mechanical properties of silicone rubber such as tensile strength and tear resistance are poor, and its physical and mechanical properties are not as good as most synthetic rubbers at room temperature. It is an amorphous substance, highly active adsorption material, insoluble in any solvent, non-toxic, tasteless, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid.
3. Advantages: 1. Anti-ultraviolet, anti-ozone, extreme temperature resistance and flame retardancy 2. Strong sealing ability, which can effectively prevent tiny particles and rain. 3. Sealing, dust-proof, moisture-proof, air-tight and light-shielding, vibration isolation, fire prevention 4. Vibration isolation used in electronic equipment and vehicle interiors 5. Cushion pads and gaskets
