Silicome Rubber is a new type of heat -resistant polymer elastic material. The biggest feature of silicon rubber is high temperature resistance and superior cold resistance, and the temperature range is between -100 degrees- 300 degrees. It has excellent aging resistance (oxygen resistance, oxidation, radiation resistance, light resistance, and climate).
In free state, after several years of exposure of outdoor exposure, the performance has not changed significantly. It also has excellent electrical insulation performance, and it is tasteless and non -toxic meets national health standards.
various characteristics and use of silicon rubber
. Heat resistance: Silicone rubber is much better than ordinary rubber heat resistance than ordinary rubber It can be used almost forever at 150 degrees without performance changes; 10,000 hours can be used continuously at 200 degrees; it can also be used for a period of time at 350 degrees.
2. Cold resistance: The normal rubber is late-20 degrees ~ -30 degrees, that is, silicon rubber still has good elasticity at -60 degrees ~ 70 degrees. Some special formulas of silicon rubber can also withstand extremely low temperatures.
3. Nuke Nature: Ordinary rubber is quickly degraded under the effect of ozone produced by electric halo and discharge, while silicon rubber is not affected by ozone. And for a long time, under ultraviolet and other climatic conditions, its physical properties have only changed slightly.
4. Electrical performance: Silicon rubber has a high resistivity and its resistance value is stable within a wide temperature and frequency range. At the same time, silicon rubber has good resistance to high -voltage electric halo discharge and arc discharge.
5. Conductivity: When the conductive fillers (such as carbon black) are added, silicone rubber has conductivity.
6. Heat conductivity: When some heat conductive fillers are added, silicon rubber has armal conductivity.
7. Anti -radiation: The radiation resistance of silicon rubber containing benzene is greatly improved.
8. Flame retardant: Silicon rubber itself is combustible, but when adding a small amount of flame resistant agent, it has flame retardability and self -extinguishing; Things, so do not smoke or release gas when burning.
9. Breath: Silicon rubber film has better breathability than ordinary rubber and plastic wax. Another feature is that it has a strong selectivity for different breathability.
Silicone rubber products are widely used in industrial machinery, aviation, automotive, electronics, construction, medicine, chemical, food and other industries. The best rubber material such as partitions, shock absorption materials, insulation elements, sealing parts outdoor sealing parts.
If: It can be used in the working environment of -60 ° C ~ 200 ° C for a long time, transparent, non-toxic, tasteless, good insulation performance, good processing performance, disadvantages: abrasion resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, and disadvantages: abrasion resistance. Tear performance and oil resistance, poor chemical media. It is widely used in electrical electrical appliances, electronics and electronics industries, aviation, national defense, machinery, construction industry, medical, food, health, and kitchen supplies, family daily miscellaneous products.
The silicon rubber is widely used in various industries:
. General industry, civil silicon rubber products;
. Food -grade silicone products: If you use a silicone fresh -keeping box sealing ring on the fresh -keeping box, for electric heating Electrical environmentally friendly silicone cushion ring, and medical equipment for molding gel;
5. It is used to manufacture general industrial or civilian color silicon rubber products;
6. For the manufacture of ducts, wires, cable shestages, silicone terminal shestages, silicone electrode cover, various silicone rubber products;
7. Used for products such as high -voltage insulators, lightning mock jackets;
8. For TV high -pressure caps, electrical sockets, rubber plates and other products required for flame retardant.
Silicon rubber has a stable silicon oxygen structure, which can give the elastic body unique performance, including biocompatibility, excellent high temperature resistance, chemical resistance, excellent mechanical electrical performance, natural transparency and translucent. A large number of experiments have proved that compared with other elastic bodies, silicone rubber showed excellent compatibility with human tissue and body fluids, and the tissue response was extremely low when implanted. Silicon rubber is colorless and tasteless, does not promote bacterial reproduction, nor will it defile or corrodes other materials. As a medical product, silicon rubber formulas are in line with FDA, ISO, and three groups of biocompatibility. Compared with most elastic bodies, silicone rubber can withstand a wide range of temperature range, and can still maintain stability when the temperature changes at -60-260 ° C, and can be radiated by ETO gas, γ-ray or E-rays, cooking and other other Methods for disinfection. Silicon rubber can withstand water and a variety of chemicals, including certain acidic substances, oxidized chemicals, ammonia and isopropanol. However, silicone rubber cannot be mixed with concentrated acids or solvents. Silicon rubber tear strength (250ppi) and tensile strength (1500PSI) are high, the elongation rate (1250%) and soft performance are excellent, and the pressure deformation rate is low. Soft silicone rubber can always maintain its softness, and the hardness of enhanced gel silicone rubber is the lowest. Silicon rubber has excellent insulation properties and functionality in electrical applications, making all comparable materials be at no way. Silicon rubber can maintain insulation and dielectric strength in extreme temperatures, and can resist the ability range of traditional insulation materials.
Silicon rubber has excellent thermal resistance, cold resistance, dielectric, ozone resistance, and atmospheric aging. The protruding performance of silicon rubber is widely used at -60 ° C (or lower temperature) to 250 ℃ (or higher temperature) for a long time. However, the mechanical properties of silicone rubber resistance and tear resistance strength are poor. At room temperature, their physical mechanical properties are not as good as most synthetic rubber, and in addition to silicon and fluorine silicon rubber, general silicon rubber oil resistance and solvent resistance performance It is not good, so Silicon rubber should not be used for ordinary conditions, but it is very suitable for many specific occasions.
