Relflex,Cisamer> PBR (Polybutadiene or Butadiene Rubber)

Relflex Cisamer PBR01

Poly butadiene Rubber or simply Butadiene Rubber is one of the oldest offerings of Relflex
Elastomers. Marketed under the brand name, Relflex Cisamer, it is an international quality product,
with high Cis content, has high elasticity and is resistant to dynamic stress, thus ensuring longer product durability.

Major application for PBR include tyres treads, tyres carcass and sidewalls, under-treads, cycle tyres, conveyor belts, sportswear,
golf balls, automotive components, conveyor belts and shoe heels and soles. PBR is also well suited for the production of flexible rollers
and mechanical goods due to its superior elasticity, resilience and abrasion properties.

Usage
– Tires
– Shoes
– Rubber hoses
– Automotive parts

Features
– Excellent process ability
– Better heat and wear resistance than natural rubber
