Classification and Market Application of Special Rubber

Special rubber refers to synthetic rubber with superior performance and more specific applications. They have excellent performance in high temperature resistance, low temperature resistance, oil resistance, chemical resistance, flame retardancy, conductivity, etc., and can meet the special needs of different industrial fields. According to different characteristics, special rubber can be divided into the following categories: silicone rubber has excellent temperature and weather resistance, and can be used in the range of -60 ° C to+250 ° C; Strong anti-aging ability, not easy to yellowing. Application: Widely used for sealing components and gaskets in high-temperature or harsh environments in aerospace, automotive manufacturing, electronics and other fields. Characteristics of Fluorosilicone Rubber (FKM/FFM): Excellent high-temperature resistance, capable of long-term operation up to 280 ° C; Simultaneously possessing excellent oil resistance and chemical corrosion resistance. Application: Suitable for seals, fuel system components in the petrochemical industry, and components that require high temperature resistance and chemical stability in the aerospace industry. Polyurethane Rubber (PUR) has the characteristics of high elastic recovery rate and excellent wear resistance, which can maintain its physical and mechanical properties over a wide temperature range. Application: Commonly used to make wear-resistant tire tread rubber, transmission belts, conveyor belts, casters, bearings, and other places that require wear-resistant materials. Nitrile Butadiene Rubber (NBR) features good resistance to various oils, as well as good wear and heat resistance. Application: Mainly used for manufacturing various oil resistant seals, such as O-rings, V-rings, and piston seals. Chloroprene Rubber (CR) features excellent resistance to ozone, UV radiation, and climate aging, as well as certain flame retardancy. Application: Mainly used for wire and cable sheaths, waterproof rolls, leather substitutes, and other occasions that require weather resistance and flame retardancy. Acrylic Rubber (ACM) features outstanding resistance to compression permanent deformation and oil resistance under high temperature conditions, especially in aromatic oils. Application: Mainly found in seals and oil resistant gaskets of aviation fuel systems. Isoprene Rubber (IR) has the characteristics of good elasticity and cold resistance, and can maintain softness in environments as low as -50 ° C. Application: Mainly used for producing seals, gaskets, and other rubber products that need to be used in low-temperature environments in refrigeration equipment. Characteristics of Carboxylated Nitrile Butadiene Rubber (XNBR): Compared with NBR, XNBR has better wear resistance, lower compression set, and higher strength and hardness. Application: Suitable for mining machinery, agricultural machinery, and engineering vehicles that require wear-resistant rubber parts. Hydrogenated Styrene Butadiene Rubber (HSR) has the characteristics of comprehensive properties similar to natural rubber, including excellent tensile and tear strength, and does not contain plasticizers, making it environmentally friendly and non-toxic. Application: Commonly used in food packaging materials, medical devices, and other products that require safe contact with the human body. With the development of technology and the continuous improvement of product quality requirements, the application of special rubber in various industries is becoming increasingly widespread. In the future, new types of special rubber will develop towards high-performance, multifunctional, green, and intelligent directions to better adapt to the diverse needs of the market.
