Silicone ring performance: 1, cold temperature. Harmless, non-toxic and tasteless. 2, high and low temperature resistance: long-term use at 200 ℃, still resilient at -60 ℃. 3, the electrical insulation properties: the dielectric properties of silicone rubber excellent dielectric properties, especially at high temperatures much higher than the general organic rubber, dielectric strength in the range of 20-200 ℃ temperature almost unaffected. 4, excellent weather resistance, resistance to ozone and ultraviolet radiation performance, long-term outdoor use in cracking does not occur. Generally believed that the silicone rubber can be used outdoors for more than 20 years. 5, excellent high temperature compression set. 6, good tensile properties apply to: small appliances (coffee maker, kettle, iron, rice cooker, frying pan, disinfection cabinet dispenser, pulp machine, toaster, water heaters, etc.) and electronics, automotive , medical and other mechanical products supporting.
