Heat stabilizers help preserve the polymer’s appearance, strength, elasticity, durability and performance characteristics. Two basic types of heat stabilizers are used in polymers: organophosphites, which protect polymers during the manufacturing process, and phenolic antioxidants that protect the polymer during its usable life. A variety of additives fall under those two

Butadiene rubber, synthetic rubber widely employed in tire treads for trucks and automobiles. It consists of polybutadiene, an elastomer (elastic polymer) built up by chemically linking multiple molecules of butadiene to form giant molecules, or polymers.The polymer is noted for its high resistance to abrasion, low heat buildup, and resistance to cracking.
The two main synthetic rubber polymers used in tire manufacturing are butadiene rubber and styrene butadiene rubber. These rubber polymers are used in combination with natural rubber. Physical and chemical properties of these rubber polymers determine the performance of each component in the tire as well as the overall tire performance (rolling resistance, wear and traction). Another important
Styrene-Butadiene rubber (SBR or Styrene-butadiene) is a synthetic rubber comprising of styrene and butadiene monomers. The random copolymer has characteristics like natural rubber and contains: Styrene content in the range of 10-25% contributing to good wearing and bonding characteristics; While the butadiene unit is composed approximately 60 to 70% trans-1,4; 15 to 20% cis-1,4; and 15 to 20%
ASTM's rubber standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of rubber and its elastomeric derivatives.
