High-temperature vulcanized silicone Overview 　　Electronic, electrical, construction, automotive These are everyday life we use to, then these lives that we can not do without the little friends in the end is what structure? Its native state is a high-temperature vulcanized silicone, silicone rubber extruded at high temperatures for a class of high-temperature vulcanized rubber. 　　High-temperature vulcanized silicone formulated 　　First, take a look at the high-temperature vulcanized silicone heat resistance What are the characteristics: 　　1 long-term use at temperatures of 200 degrees Celsius, the heat-resistant varieties contain very short period of time can also be used between 250 degrees Celsius to 300 degrees Celsius;;   　　2 Although the high temperature sulfur silicone has good heat resistance, when used in an environment heated to note ① "reversion" phenomenon, when heated in a sealed state, due to residual catalyst, resulting in a vulcanizing agent to soften; thermal expansion coefficient of vulcanized rubber ② larger thermal expansion coefficient between 2.5x10-4 to 3.5x10-4 ℃, expansion coefficient between 8 * 10-4 to 9 * 10-4 ℃. 　　Then come to understand how you want to use to make the environment more than 300 degrees Celsius? 　　1 carboxyl group added iron or iron oxide and acetylene black as the heat resistance of the additive; 　　2 The choice of carbon black, sulfur is preferably selected, a small amount of acetylene black amine, the amount of the organic titanate should vary depending on the amount of carbon black with. 　　Shenzhen Hongye Jie Silicone factory is specialized in silicone products and their production, research and development, and sales of Science and Technology Corporation.
