Definition Of  PolyButadiene Rubber (PBR)

Polybutadiene [butadiene rubber BR] is a synthetic rubber. PBR is a polymer formed from the polymerization of the monomer 1, 3-butadiene. Polybutadiene has a high resistance to wear and is used especially in the manufacture of tires, which consumes about 70% of the production. Another 25% is used as an additive to improve the toughness (impact resistance) of plastics such as polystyrene and acrylonitrile butadiene styrene (ABS). PBR accounted for about a quarter of total global consumption of synthetic rubbers in 2012. It is also used to manufacture golf balls, various elastic objects and to coat or encapsulate electronic assemblies, offering high electrical resistivity.

Applications Of PolyButadiene Rubber (PBR) 

1. Used in the inner tube of hoses for sandblasting, along with natural rubber.
2. Used in the cover of hoses, mainly pneumatic and water hoses.
3. Used in railway pads, bridge blocks, etc.
4. Used in the manufacturing of the high-restitution toy Super Ball.
5. Used as a fuel in combination with an oxidizer in various Solid Rocket Boosters such as Japan’s H-IIB launch vehicle.
6. Tires
7. Conveyor belts
8. Crack pads
9. Footwear soles
10. V-belts
11. Golf balls
