PBR 1502

SBR (Styrene Butadiene Rubber)

Reliance Stylamer SBR1502

Reliance Stylamer SBR1502 is a synthetic rubber product manufactured by the emulsion
polymerization of styrene and butadiene in low temperature. SBR has more consistent quality than
natural rubber and excellent heat and wear resistance, making it widely used for tires, shoes, and
industrial goods.

Usage
– Tires
– Shoes
– Rubber hoses
– Automotive parts

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

Stylamer is emulsion grade Styrene Butadiene Rubber (SBR) from Relflex’s elastomer range. SBR is one of the highest consumed synthetic rubbers in the world due to its versatility, enhanced abrasion resistance.
Some of the major applications of E-SBR include passenger car and light truck tyres and truck tyre retreads. It is also preferred in applications such as conveyor belts, shoe soles, V-belts, moulded rubber goods etc. It is also extensively used in the manufacture of other products such as extruded gaskets, hoses, brake & clutch pads, automobile mats, flooring, rubber toys and adhesives among others.
