What are the core characteristics of silicone rubber products that can adapt to various fields?

Silicone rubber products can adapt to multiple high-end fields, with the core being their excellent characteristics such as high and low temperature resistance, physiological inertness, and electrical insulation. Typical applications in different fields also utilize these characteristics in a targeted manner, as follows:

1. High and low temperature resistance and weather resistance: Silicone rubber can usually maintain elasticity for a long time at -60 ℃ to 200 ℃, and some special silicone rubber such as phenyl silicone rubber can still work normally at extreme low temperatures of -73 ℃, and can even withstand short-term environments of 300 ℃ at high temperatures; At the same time, it has outstanding resistance to ozone and ultraviolet radiation, and is not easily cracked even after being used outdoors for more than 20 years. In the aerospace field, this characteristic makes it suitable for manufacturing spacecraft seals, high-temperature resistant cable insulation layers, etc., which can resist extreme temperature differences and cosmic ray erosion in space; In the automotive field, it can be used to make sealing rings and spark plug sleeves around the engine, suitable for high temperature environments during engine operation and harsh outdoor weather.
2. Physiological inertness and biocompatibility: Qualified silicone rubber is non-toxic and odorless, does not cause rejection reactions in human tissues, and does not cause coagulation, making it an ideal medical biocompatible material. This feature makes it widely used in the medical field, such as in the production of implantable products such as artificial heart valves, artificial blood vessels, and tympanic membrane repair patches. The thickness of the tympanic membrane repair patch is only 0.1mm, and after microporous treatment, it not only supports tympanic membrane repair but also does not affect sound wave transmission; It can also be used for medical consumables such as syringe pistons, catheters, burn dressings, etc., ensuring the safety of clinical use.
3. Excellent electrical insulation performance: Silicone rubber has excellent dielectric properties, with dielectric strength almost unaffected by temperature in the range of 20-200 ℃, and can resist arc erosion. Even in extreme environments such as high temperatures, its insulation performance far exceeds that of ordinary organic rubber. This feature makes it indispensable in the field of electronics and electrical engineering, such as for making conductive buttons for mobile phones, silicone buttons for remote controls, high-voltage cable accessories in power equipment, insulation seals for electronic instruments, etc., which can ensure the stable operation of electronic equipment and power systems.
4. Good processing and formability: Silicone rubber can be made into products of different shapes through various processes such as molding, extrusion, injection, etc. It can produce complex precision components and large-area sealing materials. For example, in the daily consumption field, it can be made into silicone protective cases for mobile phones and silicone kitchenware for kitchens; In the industrial field, it can be processed into shock-absorbing pads for mechanical equipment, pipeline sealing strips, etc., to meet the diverse form requirements of different scenarios.
