Further
Comments
This is the highest volume general purpose synthetic rubber.
It is very weak unless reinforcing fillers are incorporated.
With suitable fillers, it is a strong rubber, although not
approaching natural rubber or polychloroprene. Otherwise,
it has similar chemical and physical properties to natural
rubber, with generally better abrasion resistance but poorer
fatigue resistance. |

Styrene
Butadiene Rubber (SBR)
Styrene Butadiene Rubber
is made from styrene and butadiene by low temperature emulsification
polymerization and has various rubber characteristics for common
use. The SBR 1500 series is produced under exact process from
polymerization to final products, to satisfy diverse demands of
customers. The 1700 series is made from high molecular weight
product with oil, has excellent valence of physical properties.
