thermoplastic elastomers (TPE) & thermoplastic rub

what is it

thermoplastic + Elastomer = TPE/TPR

TPE are a group of polymers that combine the properties of thermoplastics and elastomers.they often feel rubbery.


  • they can be processed like conventional thermoplastics e.g. injection moulded.
  • easier to manufacture over a thermosetting plastic as it is quicker to make the product.
  • all waste and scrap can be recycled.

Elastomers: elastomers have long-chain molecules that can be considered to be coils; when the material is distorted (compressed or streched) the materials distort, and when realeased they return to thier original shape. These coiled molcules give the Elastomers their elastic properties.

Liquid silicon Rubber (LSR)

What is it

 Made up of 2 components, once combined it will harden. behaves like a thermosetting plastic.

manufactured:  similar to injection moulding. The ram forces the two liquids in the chamber & heats the polymers for cross-linking to occur.The polymers can the be formed into the prodeuct.


  • maintains insulating & elastomeric qualities over wide ranging temperatures e.g. -50 to 250 degrees.
