Advantages of silicone products
1. High temperature resistance: applicable temperature range is -40 to 230°C, and can be used in constant temperature and humidity test chambers.
2. Easy to clean: Silicone products produced from silicone can be restored to cleanliness by rinsing with water after use, and can also be cleaned in a dishwasher.
3. Long life: The chemical properties of silicone materials are very stable, and the products produced have a longer life than other materials. For example, the life of thermally conductive silicone can reach 10 years or even longer.
4. Soft and comfortable: Thanks to the softness of the silicone material, it is extremely flexible and does not deform.
5. Various colors: Different beautiful colors can be blended according to customer needs, and personalized styles can be customized.
6. Environmentally friendly and non-toxic: No toxic or harmful substances are produced from the entry of raw materials to the shipment of finished products.
7. Electrical insulation performance: Silicone rubber has high resistivity, and its resistance can remain stable over a wide temperature range and frequency range. At the same time, silica gel has good resistance to high-voltage corona discharge and arc discharge, such as high-voltage insulators, TV high-voltage caps, electrical components, thermal pads, etc.
8. Low temperature resistance: The critical point of ordinary rubber's operating temperature is -20°C to -30°C. However, silicone rubber still has good elasticity at -60°C to -70°C. Some specially formulated silicone rubber can also Withstand extremely low temperatures, such as low-temperature silicone seals, etc.
9. Conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has good conductive properties, such as keyboard conductive contact points, electric heating element components, antistatic components, high-voltage cable shielding, medical therapy conductive film, etc.
10. Weather resistance: Ordinary rubber degrades rapidly under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone, and its physical properties only change slightly when exposed to ultraviolet rays and other climate conditions for a long time, such as outdoors. Sealing materials used, etc.
11. Thermal conductivity: When certain thermal conductive fillers are added, silicone rubber has good thermal conductivity, such as heat sinks, thermal seals, copy machines, fax machine thermal rollers, etc.
12. Radiation resistance: The radiation resistance of silicone rubber containing phenyl groups is greatly improved, such as electrically insulated cables, connectors for nuclear power plants, etc.
The superior performance, coupled with the fact that silicone is a non-petroleum product and does not rely on increasingly scarce petroleum resources, makes silicone products a substitute for similar plastic products. At the same time, silicone products can be applied to many areas of use that plastic products cannot. Such as thermally conductive silica gel, etc., their application prospects are very broad.
Silicone products can be divided into four major categories according to different molding processes:
1. Liquid silicone
Liquid silicone products are spray-molded through silicone injection molding. The product is soft and the hardness can reach 10°C-40°C due to its soft characteristics.
Liquid silicone is widely used in simulated human organs, medical silicone breast pads, etc.
2. Molded silicone
Molded silicone products are usually formed by placing solid silicone raw materials with a vulcanizing agent in a high-temperature mold and then applying pressure through a vulcanization machine to solidify the high-temperature sulfur. The hardness of the molded silicone is usually between 30°C and 70°C. The raw materials are combined with the color paste to adjust the color according to the Pantone color card number. The shape of the mold determines the shape of the molded silicone products. Molded silicone products are currently the most widely used in the silicone industry.
Molded silicone is mainly used to make silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key cases, mobile phone cases, silicone kitchenware, silicone mats, ice trays, cake molds, etc.
3. Extrude silicone
Extruded silicone products are usually formed by extruding silicone through an extrusion machine. Generally, the shape of extruded silicone is long strips, and tubular ones can be cut at will. However, the shape of extruded silicone has limitations.
Extruded silicone is widely used in medical devices and food machinery.
4. Special products
Special silica gel products are based on the chemical properties of silica gel or the addition of some auxiliary raw materials. Special silica gel products can also be high temperature resistant (up to 330 degrees), food grade (fully compliant with US FDA, LFGB standards), medical grade, and flame retardant grade , by adding auxiliary raw materials, it can also have properties such as luminous, negative ions, color change, etc.
