EPDM rubber is an amorphous terpolymer. This polymer has good stability when processed at high temperatures. Due to its structure and composition, EPDM polymer is also resistant to ozone and weathering. This compound is generally suitable for outdoor applications or high ozone levels without the need for antioxidants. EPDM can be applied to inner tubes to improve resistance to low temperatures, aging, and processing characteristics.
SBR is a commonly used elastomer. This rubber is a butadiene copolymer containing 10-25% styrene. The styrene content will increase strength and abrasion resistance, reduce price, and improve compatibility with other blends. SBR has excellent resistance to brake fluid and weathering when protected by additives.
NBR is a synthetic rubber that has good resistance to oil, fuel and other chemicals, but is not resistant to weathering and ozone. The higher the nitrile content, the greater the resistance to oil but the lower the flexibility. Commonly used in the automotive industry, gaskets, oil seals, o-rings, engine hoses and other spare parts.
IR is a widely used commercial rubber. This rubber is obtained in the form of latex from rubber trees (NR) or is produced synthetically by polymerizing 1-methyl-1,3-butadiene (IR). Polyisoprene is an excellent choice for applications at room temperature and low temperatures. Its elasticity, resistance to pressure, and abrasion resistance are excellent above normal temperatures. The disadvantage is that Isoprene has poor resistance to ozone, gasoline and many other organic solvents.
SSBR is a type of SBR with special molecular structure. With good processability and dynamic property properties. widely used for high performance and fuel-efficient tires.
IIR is a copolymer of isobutylene and contains a small amount of isoprene, which provides unsaturated areas for vulcanization. This polymer has very low gas permeability and excellent resistance to UV, oxygen and ozone. IIR also has excellent chemical resistance and temperature stability. Commonly used for inner tubes.
BIIR is a copolymer of isobutylene and a small amount of brominated isoprene that provides unsaturated areas for vulcanization. This elastomer has many of the attributes of butyl rubber, including low gas and moisture permeability, good vibration damping, excellent resistance to aging and weathering. This rubber is most widely used for bicycle inner tubes, trucks, industrial tires, agricultural tires, rubber seals, membranes, tank linings, conveyor belts, engine mounts, etc.
CIIR is a copolymer of chlorinated isobutylene and small amounts of isoprene that provides unsaturated areas for vulcanization. The chlorinated areas become more reactive, providing faster curing times with better adhesion to unsaturated rubber and metals. CIIR is also resistant to weather, ozone, chemicals and weathering, making it widely used in tank linings, conveyor belts and protective clothing.

Accelerator is an important ingredient of the vulcanization process. Accelerator will increase the maturity ratio of the compound and the efficiency of sulfur bonding with rubber macromolecules in the form of cross-linking. Accelerator significantly reduces the time and temperature required for vulcanization, as well as reducing the sulfur content in the rubber compound.
Activators are chemicals used to activate accelerators. These materials reduce the vulcanization time (curing time) by increasing the maturity of the compound.
Antidegradant is a protective agent for polymers by slowing down the aging or degradation process when exposed to degradative environments such as: storage, oxygen, heat, UV light, weathering, ozone, etc.
Antioxidants are used to protect polymers from degradation caused by oxygen.
Antiozonants are chemicals that prevent the breakdown of compounds due to ozone.
Peptizing Agent is an additive in the rubber industry that helps the mastication process of rubber raw materials and reduces the mastication process time. The use of Peptizing Agent can save energy used and increase the capacity of the machine to process rubber raw materials. Peptizing Agent is widely used during the processing of natural rubber because it does not affect the vulcanization process and the properties of the resulting rubber compound.
Plasticizer is one of the raw materials in the manufacture of rubber compounds. This material is used to facilitate the processing of rubber raw materials by reducing the viscosity of the rubber compound, and also to help process raw materials at lower temperatures.
Processing Aid is a material that accelerates the process of breaking double bonds of a polymer. Processing Aid also helps to mix rubber compound additives. Adding Processing Aid in the compounding process can reduce costs and energy consumption during processing.
Retarder can reduce the speed of curing time in the early phase of the vulcanization process. Retarder can also increase safety during the compounding process.
Rubber processing oil is used during the mixing of rubber compounds. These oils can be natural or synthetic, to help improve the dispersion of fillers and the properties of the rubber compound. There are 3 types of rubber processing lubricants commonly used for production: aromatic, paraffinic, and naphthenic.
Calcium carbonate is used as a filler in the rubber compounding process which can increase the stiffness of the polymer. This material also helps reduce the cost of production materials.
Silica is used as a filler that adds rigidity to the rubber compound production results. In addition to increasing polymer rigidity, this material also helps reduce the cost of raw materials for production. Silica is combined with carbon black as a filler in rubber compounds that can increase the strength properties of the compound.
Zinc oxide (ZnO) is an activator in the vulcanization process that uses sulfur as an auxiliary material. The use of this material can increase the efficiency of the vulcanization process.
