The characteristics and uses of silicone rubber sealing strips
The performance and advantages of silicone sealing strips have not changed significantly after being exposed to outdoor exposure for several years in a free state. And has excellent electrical insulation properties, and is odorless, non-toxic and in line with national health standards.
Characteristics and uses of silica gel strips:
1. Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber. It can be used almost forever at 150 degrees without performance changes; it can be used continuously at 200 degrees for 10,000 hours; it can also be used at 350 degrees. Can be used for a period of time. Silicone sealing strip.
2. Cold resistance: Ordinary rubber strips are delayed from -20°C to -30°C, that is, silicone rubber still has good elasticity at -60°C to -70°C. Some specially formulated silicone rubber can withstand extremely low temperature.
3. Weather resistance: Ordinary rubber strips are rapidly degraded under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. And under ultraviolet light and other weather conditions for a long time, its physical properties have only slight changes.
4. Electrical properties: The silica gel strip has high resistivity and its resistance remains stable in a wide range of temperature and frequency. At the same time, silicone rubber has good resistance to high voltage corona discharge and arc discharge.
5. Conductivity: When conductive filler (such as carbon black) is added, the silica gel strip has conductivity.
6. Thermal conductivity: When some thermal conductive fillers are added, silicone rubber has thermal conductivity.
