What is the rubber composition of sole?

Answer:

Styrene butadiene rubber (styrene butadiene rubber) is a kind of macromolecule elastomer material synthesized by copolymerization of butadiene and styrene as main monomers. Its quality is even and pure, and impurities are mixed little. It can be dissolved in benzene, toluene, gasoline, chloroform and other organic solvents. The unsaturated double bond in the styrene butadiene rubber molecule and the vulcanizing agent form a cross-linked network structure by substitution or addition reaction, and the styrene butadiene rubber vulcanizate reinforced by the reinforcing agent has higher physical and mechanical properties.Styrene butadiene rubber vulcanization rate is slow, but vulcanization flatness is good, not easy to over vulcanization, with aging resistance, heat resistance, wear resistance, and other excellent performance.
The sole of high pressure polyethylene and rubber flavor, rubber and plastic used together.Student: Rubber soled heavy, expensive, not resistant to oil, heat. Variable color.
Plain rubber sole (RB):RB is the abbreviation of English Rubber (rubber). It is molded by hot pressing and divided into natural rubber and reclaimed rubber. The quality of heavy, non - oil, mold must be rough at the surface of the joint surface, it is easy to shorten when heated, the color is inconsistent.Advantages: good abrasion resistance, anti slip, elastic, not easy to break, good softness, good stability, extended shrinkage, good hardness, good flexibility, waterproof.Disadvantages: the heavier, Yi Tushuang (the quality problem), corrosion resistance (environmental protection); not hard, easy to pierce; permeability, moisture absorption is not good, not afraid of oil immersed in the automobile gas station oil contact place wear.
