Synthetic rubber, while not as common as natural rubber, is still important and is used to make a variety of products. Furthermore, it has outstanding shear resistance: it does not slip from the surface in the case of a lateral load. This rubber is composed principally of about one part of styrene and about three parts of butadiene and is known as styrene-butadiene rubber, or SBR; it was formerly known as Buna-S -and GRS. The properties of synthetic polyisoprene (PI) cannot rival that of NR, although synthetic PI can achieve similar molecular chain structure (for example molecular weight and molecule chain . It has properties similar to natural rubber, but with greater wear, water and abrasion resistance. Of rubbers by vulcanization are getting rubber and ebonite. Rubber produced by artificial chemical process is known as "synthetic rubber". Other disadvantages include: Low elongation at break Low hot tear strength Hysteresis, resilience . When raw rubber is heated, it becomes sticky, and when it is in colder temperatures, it tends to break, just like the synthetic variety. In this illustration, the dashed lines represent repetition of the same base units, so both the products and reactants are polymers. A elastomer is a material with the mechanical property that it can undergo much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation. Synthetic rubber also tends to be cheaper to produce. Synthetic rubber is commonly known for its elasticity. (ENS RUBBER) ELASTOMER NON-SKID RUBBER.
