Styrene Butadiene Rubber (SBR)

Styrene Butadiene is a synthetic rubber commonly used to substitute natural rubber

A fantastic general purpose elastomer, Styrene Butadiene is often preferred to natural rubber as a result of its abrasion resistance.  Although it is inferior in terms of fatigue resistance,  it has the ability to fulfil many roles and applications.

Southbourne Rubber manufacture everything from the soles of shoes to car tyres from this material which is in high global demand.

What is Styrene Butadiene?

Also referred to as Buna-N, this material is a copolymer of styrene and butadiene, the latter of which determines the rubber's flexibility and toughness. 

It affords customers greater performance longevity in terms of the effect of heat on the aging process of the material.  SBR has several advantages over NR with greater resistance to water, heat, abrasion and flexibility in low temperatures. 

It has good ability to insulate electrical components, resists alcohol, solvents and weak acids.

Applications

We are able to utilise SBR for our rubber bonding (metal and plastic bonding components) which is an important material capability.

The use of this material instead of natural rubber for tyres continues in today’s automotive industry.  We support this area of manufacturing and others where alcohol, water and chemicals involved in braking systems are used.

We have a large number of standard components manufactured in SBR available in a range of sizes.  We are also able to offer a fully customisable component service to those requiring a bespoke specification.

Components in high demand from our customers include tubing, gaskets, seals, anti-vibration shock mount parts and rubber belts.
