Properties / Thermoplastic Elastomer Applications

What are Thermoplastic Elastomers?

Thermoplastic elastomers (TPEs) are a form of thermoplastic polymers. They are also a class of copolymers, or a physical mix of rubber and plastic polymers, that consist of both thermoplastic and elastomeric properties. TPEs are also referred to as thermoplastic rubber, as it exhibits some of the performance properties of rubber. However, TPEs are processed similarly to plastic and are recyclable.

The elastomeric component of TPEs make them soft and flexible, so they can be stretched to their twice their initial length. They will return to their original length upon release. TPEs are soft to the touch, so they are ideal for a variety of markets and consumer goods. Furthermore, soft thermoplastic elastomers are easy to mold and extrude onto other TPEs. As a result, they are ideal for soft grips on products as well as sealing rings and bottle cap liners.

There are also six generic classes of commercial TPEs:

  • Styrenic block copolymers, TPS (TPE-s)
  • Polyolefinelastomers, TPO (TPE-o)
  • Vulcanizates, TPV (TPE-v or TPV)
  • Polyurethanes, TPU (TPU)
  • Copolyester, TPC (TPE-E)
  • Polyamides, TPA (TPE-A)
  • Unclassified thermoplastic elastomers, TPZ

These other types of TPEs can be utilized in the manufacturing of wire and cable insulation, HVACs, automotive parts, and home appliances.

Qualiform Proprietary Blend

In addition to our Thermoplastic elastomers, Qualiform offers proprietary blends with reinforcing fibers. We blend these reinforcing fibers directly into the TPEs. As a result, your thermoplastic elastomers will have increased resistance to impacts and abrasions as well as improved durometer, toughness and performance. Qualiform also offers this proprietary blend for other available materials:

  • Butyl Rubber
  • EPDM Rubber
  • Natural Rubber
  • Neoprene Rubber
  • Nitrile Rubber
  • Synthetic Rubber
  • Thermoplastic Elastomers (TPE)
  • Viton Rubber
