WHAT IS TPE?

What is TPE(Thermoplastic Elastomers) ?

Thermoplastic Elastomers (TPE) can be processed in all the plastic extrusion and injections lines. They don't need to be vulcanized.

General Properties:
Low Density
Wide Range of Hardness
Good Resistance to UV & Ozone
Wide Temperature Range
100% Recyclable
Low Compression Set 
Due to colorabilty, investment cost and production costs are low.

TPE has 2 phases - Soft and Hard

Due to this structure TPE materials have good elasticity and good resistance to atmospheric conditions. Additionally, they have good resistance to temperature, strength and formability similar to rubber materials.

As you can see from the Polymer tree, TPE (Thermoplastic Elastomers) is gathered from 4 subtitles

Types of TPE's:

  • Thermoplastic Vulcanizate(TPV)
  • Styrenic Block Copolymers (SBS, SEBS)
  • Thermoplastic Polyolefins (TPO)
  • Thermoplastic Polyurethane (TPU)
  • Polyether Block Amide
  • Copolyester 

What is TPV?

TPV (EPDM/PP), Thermoplastic Vulcanizate, is produced by combination of EPDM rubber (Elastic phase) and Polypropylene (Thermoplastic phase). The EPDM/PP compound produced by this method has good mechanical properties such as EPDM elasticity, low compression set and UV & Ozone resistance. Beside these properties the TPV materials have excellent formability in the injections and extrusion machines.

General Features of TPE Materials

Hardness
Thermoplastics can be produced in any hardness between 20 Shore A up to 70 Shore D.

UV & Ozone Resistance 
TPV has an excellent resistance against UV and Ozone

Resistance to Temperature
 
TPVs can withstand temperatures from -40°C up to 130°C. Therefore, our seals can easily be used in all locations without any deformation.

Colour Options
There is no limitation on coloring any material made up of TPVs. Any choice of yours from the RAL catalogue can be produced.  

Recycling
TPE is 100% recyclable material. It isn't harmful to the environment.

Weld Ability
TPE is heat processing material. It can be produced through CO-EX and CO-Injection. Welding TPE is quite easy and gives excellent results.

Compresion Set
Due to TPE's elastomeric phase, they have high compression set values in case of both static and dynamic loads.
