Specialty silicone offers more unique features compared to ordinary silicone, such as high-temperature resistance, extreme cold resistance, antistatic properties, flame retardancy and fire resistance, foamability, electrical conductivity, liquidity, oil resistance, and self-lubricating capabilities even when exposed to oil.
 
Specialty silicone is an independently developed product designed to meet the unique performance requirements of specialized applications. It is widely used in fields such as electronics, electrical appliances, industry, aerospace, security, mother-and-baby products, and more. Thanks to its outstanding properties, specialty silicone fulfills the high demands placed on devices or consumer goods in both production and daily life, playing an indispensable and unique role in various industries.
 
What are the types of specialty silicone?
 
1. Anti-static Silicone
 
Anti-static silicone can achieve a surface resistance ranging from 10⁵ to 10⁹ ohms, offering excellent anti-static performance. It is widely used in the manufacturing of suction cups, rubber rollers, buttons, sealing rings, phone cases, wrist straps, game controllers, electronic device trays, keyboard protective films, protective covers for mining equipment housings, and various other anti-static silicone products. Additionally, anti-static silicone comes in versatile models that also feature flame retardancy, high and low-temperature resistance, superior resilience, and foamability, catering to the unique needs of even more customers.
 
2. High-Temperature Resistant Silicone
 
High-temperature silicone is specially designed for products operating under extreme heat conditions, primarily available in two categories: resistant to 300°C and 350°C. These materials maintain their shape even under prolonged exposure to high temperatures, exhibit excellent anti-aging properties, and offer superior resilience. They are widely used in manufacturing a variety of high-temperature silicone products, including suction cups, electronic device trays, miscellaneous components, tubing, oven sealing strips, and heat-resistant protective covers.
 
3. High-Temperature Resistant and Flame-Retardant Silicone
 
It simultaneously offers performance with high-temperature resistance up to 250°C and flame-retardant properties meeting the U.S. UL-94V0 standard. This provides an optional solution for products with stringent safety requirements.
 
4. Fire-resistant Foam Silicone
 
It is a fire-resistant, foam-type silicone rubber with a foaming ratio that can reach up to 300%. After vulcanization, it transforms into a soft, elastic material, expanding in volume to three times its original size. This versatile silicone can be used to create flexible rubber products such as body molds, shoe insoles, shoulder pads, patches, and anti-slip mats. Additionally, it’s ideal for manufacturing various wire and cable jackets, hoses, flame-retardant foam silicone strips, and any other flame- or fire-resistant silicone products produced via extrusion or calendering processes.
 
5. Low-Temperature Resistant Silicone
 
Low-temperature silicone is designed specifically for products that can maintain normal functionality even under extremely cold conditions. It performs reliably at temperatures as low as -70°C, ensuring long-term operation without degradation. Additionally, this silicone boasts exceptional tear resistance, excellent elasticity, minimal yellowing, and a pleasant tactile feel. The material can be molded or extruded, making it ideal for manufacturing a wide range of silicone products, including suction cups, electronic device trays, miscellaneous components, tubing, sealing strips for cold storage rooms, and ultra-low-temperature protective sleeves.
 
6. Conductive Silicone
 
Conductive silicone is widely used in numerous fields, including electronics and appliances, mobile communications, healthcare, aerospace, and transportation. The key distinction lies in modifying the insulating properties of ordinary silicone to give it conductive—or even superconductive—capabilities, resulting in a specialized type of silicone. Conductive silicone can be customized with surface resistivity ranging from 0.5 to 2000 Ω·cm, making it ideal for applications such as various zebra strips, conductive black granules, conductive tips for phones and laptops, highly responsive capacitive screen styluses, shielding materials, conductive wristbands, conductive silicone sheets, and conductive silicone pads.
 
7. Liquid Silicone
 
Specialty liquid silicone rubber is primarily categorized into two main types: flame-retardant foaming silicone and mold-making silicone. The latter also boasts excellent high-temperature resistance, capable of enduring up to 350°C, making it ideal for crafting food molds—such as candy and cake molds—as well as metal crafts, precision mold production, toys, alloy automotive components, large-scale cement structures, sandstone sculptures, molds for plaster products, rubber sheets, rubber wheels, and other specialized applications.
 
8. Oil-Resistant Silicone
 
Oil-resistant silicone is specially developed and customized for withstanding plant-based olive oil, safflower oil, makeup remover oil, motor oil, greases, mineral oil, fuels, ASTM test oils, brake fluids, and other similar oils. It is widely used in oil-resistant products such as sealing plugs, kitchen utensils, mobile phone buttons, work gloves, oil-resistant jackets, and various accessories. Additionally, this material boasts exceptional properties like resistance to heat radiation, cold temperatures, acids, alkalis, corrosive gases, and water.
 
9. Oil-Release Self-Lubricating Silicone
 
Products made from oil-exuding silicone can continuously release oil during use, achieving a unique self-lubricating property. This enhances the product's sealing performance and extends its service life, while also providing excellent features such as dust resistance and anti-stick properties. These products are widely used in manufacturing seals, air pump plugs, hydraulic plugs, and various other lubricative silicone items.
 
Specialty silicone, when used in different products, faces significantly varying conditions and environments. Therefore, both the supplier and the customer need to thoroughly confirm the product's operating parameters before proceeding with a tailored, customized design.
 
This means that companies with expertise in the R&D and production of specialty silicones, leveraging their more advanced technical capabilities, can more precisely meet product performance requirements and customers' actual needs, thereby gaining a stronger competitive edge in the market.
