Polybutadiene is an ideal compound for creating tough rubber parts

With its hard wearing and non-conductive nature, Polybutadiene is an ideal compound for creating tough rubber parts.  Of all the rubber types available, this makes up approximately 25% of the total global consumption of synthetic rubber.

In terms of our use of this material, Southbourne Rubber often create a blend with Styrene Butadiene Rubber (SBR) and natural rubber.  This enables us to achieve the optimum performance for our customer and the rubber parts we manufacture for them.


What is Polybutadiene?

This synthetic rubber material has an excellent ability to resist wearing with non-conductive properties. 

We utilise this material for its strength and dexterity for the rubber parts we manufacture.  High elasticity, good abrasion and tear resistance are key characteristics. 



This material is added to plastics to change them from a brittle material to one that is more pliable.  It is then possible for the components to have greater resistance to deformity and maintain their toughness.

Southbourne Rubber use this material for components entering the healthcare and food production industry.  In addition, it is a high-demand material for the electronics industry as a coating for electronic assembly parts.

For companies involved in activities such as sandblasting, the sand delivery hosing may have a central core of Polybutadiene.  It is the increased resilience to wear and tear of this material that makes it ideal for this type of application.

As well as being highly durable, it also has strong performance at low temperatures.  This makes it of particular use in the transport industry to help improve the tyre tread and side walls. 

Key BR material features:

  • Ideal for use in critical end user applications such as within aircraft and healthcare due to stringent testing and certification
  • PTFE can be used to create a non-reactive barrier to prevent corrosion on pipework delivery systems
  • Can be used to create a lubricant to reduce friction between surfaces in various manufacturing processes
