1 of natural rubber (NR) overall performance is more comprehensive, simple processing, drawback is oil, heat, cold, chemical resistance, poor anti-aging properties, far less than other synthetic rubber. Mainly used in tires, hoses, tape, medical supplies, sporting goods and other industrial supplies.
2 styrene-butadiene rubber (SBR) and natural rubber fairly comprehensive performance, and abrasion and heat aging properties are better than natural rubber, natural rubber and various synthetic rubber and with good workability, is a universal rubber. The main use of language hoses, tires, plastic. Shoes, as well as a variety of industrial rubber products.
3 good butadiene rubber (BR) processing performance, excellent wear resistance and elasticity, less heat, good low temperature performance. Flex resistance is also good, the disadvantage is not good tear strength and slip resistance. Widely used in tires, hose, belt, shoes and other rubber products aspects.
4 chloroprene rubber (CR) ozone resistance, resistance to weathering, performance, oil resistance, solvent resistance, flame retardant, insulation and water resistance, air tightness, tensile strength and other aspects are good. The disadvantage is poor cold, specific gravity (density) is large. Suitable hose, belt, conveyor belt, wire and cable, air conditioning rubber products, as well as construction, shipbuilding, automotive and other sealing products.
5 nitrile rubber (NBR) long-term temperatures below 120 degrees, airtight better (after butyl rubber) oil, wear and tear and other performance features excellent (Note: This material is a semiconductor rubber therefore unfit for insulating product) for the automotive, mechanical hoses, seals, cable sheathing, sponge products.
6 hydrogenated nitrile rubber (HNBR) -40-180 degrees can be long-term work environments, good workability, high strength, excellent wear resistance, permanent deformation is small, but also has a unique resistance to ozone and resistance to hydrogen sulfide role. Suitable for engine sealing products, oil seals, oil, drill rubber products, low temperature tubing, air-conditioning tubes, electronic system protection components.
7 EPDM rubber (EPDM) heat resistance, ozone is a weathering resistance, low temperature resistance, electrical insulation excellent performance in all aspects, acid, alkali and so on. Widely used in construction, automobiles, ships doors and windows sealed, wire and cable, automotive, motorcycle parts and other industrial products.
8 silicone rubber (SR) -60-120 degrees in the long-term use of the work environment, transparent, non-toxic, odorless insulation performance is good, good processing performance. The disadvantage is that wear resistance, tear resistance and oil resistance, chemical resistance poor. Widely used in electric appliances, electrical and electronics industry, aerospace, defense, machinery, construction, industrial, medical, food hygiene fields, as well as kitchen supplies, household products, and other miscellaneous household.
9 Viton (FPM) excellent high temperature (250 degrees) and good dielectric properties, and excellent oxidation resistance, oil resistance, chemical corrosion resistance, wear resistance, excellent performance. The disadvantage is a more difficult process. Widely used in aerospace and missile rocket science, etc., and all aspects of industrial equipment, such as hoses, seals, wires, diaphragms, tape and other products, as well as anti-corrosion lining.
10 butyl rubber (IIR) tightness best in a variety of rubber, excellent heat aging resistance, ozone aging resistance, and electrical insulation properties, a colleague has a wide range of temperatures. Widely used in tire inner tubes, vulcanization capsule, water births, wind tires, auto parts, wire and cable, hose, tape, building waterproof sheets, the plugging material (such as medicine bottle) seal doors and windows, as well as anti-corrosion chemical equipment Wait.
11 Thiokol (TR) has good oil resistance, hydrocarbon solvents, resistance to atmospheric aging, water, and low temperature flex better. While a variety of materials have very good adhesion, as automotive sealing material, non-drying putty rubber and chemical equipment lining, road paint and oil paints, coatings, oil-resistant hose hollow glass seals.
12 polyacrylate rubber (ACM and ANM) temperature up to 175-200 degrees, air tightness, resistance to weathering, heat resistance, oil resistance are good. The disadvantage is that the water resistance, poor low temperature performance. Processing performance is difficult to grasp, vulcanization process for mold corrosion. Hose used seals and special requirements of the automotive industry, tape, colleagues also used in manufacturing contact with hot oil, gloves, wire and cable, adhesives.
13 ethylene vinyl acetate rubber (EVW) long-term use at 175 degree heat, excellent flame resistance and oil resistance, the product under high temperature deformation is small. Suitable for subway, high-rise buildings, as well as marine high performance flame retardant wires and cables and other sealing products.
14 chlorinated polyethylene (CPE) is a heat-resistant, weather, fire special synthetic rubber, excellent electrical properties and chemical behavior, and in addition also has oil, ozone, weathering, heat aging resistance, fire, etc. , widely used in wire and cable flame good weather resistance, sealing products and requiring temperature, acid, fire hose, tape and rubber rollers and other industrial products.
15 thermoplastic styrene-butadiene rubber (SBS) is currently the largest production (7%) of the thermoplastic elastomer varieties most economical, similar to its performance and SBR have more flexibility, rich feel, color, format, and make low-hardness products. The disadvantage is that heat, poor oil resistance. Widely used in handles, toys, sports equipment, shoes and other fields.
16 thermoplastic elastomer (SEBS) is obtained by hydrogenation of saturated SBS, anti-aging, ozone resistance, a substantial increase in the original performance is especially suitable for outdoor use products. The disadvantage is that heat resistance, poor oil performance. Operating temperature range is between -60-100 degrees. Widely used in handles, toys, sports equipment, medical accessories, and other fields.
17 The thermoplastic elastomer (TPV) is a dynamically vulcanized EPDM / PP blend. Cold and heat resistance, excellent flexibility, anti-aging, ozone resistance, tear strength, excellent resistance to chemicals, color performance, long-term use temperature between -60-135. Widely used in automobiles, ships, machinery parts, hose tape and various industrial products, commonly used in various types of seal extrusion.
18 Thermoplastic Polyurethane (TPU) outstanding wear resistance, high flexibility, high mechanical strength, excellent oil resistance, excellent flex resistance, long-term use may be between -40-120 degrees temperature. The disadvantage is that rare breed of low hardness. Widely used in the automotive industry brake pipe, tubing, interior parts, cables, pipes, shoe and sports equipment, heterosexual materials.
19 Polyvinyl Chloride (PVC) is one of the most widely used plastic varieties, economy and has excellent flame resistance, chemical resistance, high abrasion resistance, electrical insulation. The disadvantage is that the difference between cold winter, hard and brittle, their chlorine irritating. Widely used in various industries, automotive, construction, machinery, cable and other daily necessities. Seal doors and windows and other areas heavily used.
