PROCESSING OF THERMOPLASTIC RUBBER

ARTICLES IN DURABLE ELASTIC RUBBER

Poly(styrene-butadiene-styrene), or SBS, is a resistant rubber used for a variety of articles like the soles of shoes and boots and everything else that requires durability to be its key feature. It is called a block copolymer. Its skeleton is formed of three segments: the first is a long chain of polystyrene, the central piece is polybutadiene and the last segment is another long section of polystyrene.

SBS is also an unusual type of material called a thermoplastic elastomer.

These are materials which behave like elastomeric rubbers  but, when heated, can be processed like thermoplastics. Most types of rubber are difficult to process because they are crosslinked. SBS and other thermoplastic elastomers, however, are rubbery without being crosslinked, and can, therefore, be easily shaped.

Other types of plastic rubber processed by the Alalede Group:

  • granules
  • TPV
  • TVE
  • UBS
