injection molding of thermoplastic elastomers or thermo-elastic plastics

Our company has experience with injection molding of thermo-elastic plastics.

What is an elastomer:


The Wikipedia defines a TPE of :sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers that consist of materials with both thermoplastic and elastomeric properties.

This means that it ‘s  plastic material, or in it’s rough from  bough as granulate resin,  that can be simple injection molded , and out of the mold it behaves like a natural rubber.



We have made TPE parts for medical use.; See the movie hereunder.

Other Applications of thermoplastic elastomers
Profiles, gaskets, medical components, bellows, grip surfaces, shoe soles, conveyor belts, membranes, o-rings, vibration dampers, ski boots, running wheels, tires (internal transport)

ThermoPlastic Elastomer

Collective name for a group of thermoplastic polymer blends of a ‘hard’ polymer with elastomer particles. Depending on the polymer used in the blend, a TPE is further distinguished from Polyamide-TPE (TPA), Copolyester-TPE (TPC), Olefin-TPE (TPO), Styrene-TPE (TPS), Urethane-TPE (TPU), TPE. with a cross-linked rubber (TPV) and special TPEs (TPZ)

Specific properties 

0.97 – 1.27 g / cm3 (depending on the type of TPE)

Mechanical properties:

Varying from very flexible and tough to relatively stiff and brittle. TPUs have an exceptionally high wear resistance.


Depending on the type of variable from approx. 25 shore A to approx. 80 shore D.

Thermal properties:

Depending on the type: can be used from -60 ° C to + 150 ° C.

Color / surface
TPEs are not transparent; well colored. Some versions do not allow bright colors.



Thermoplastic elastomeres are good injection moldable;
Most TPEs are easily glueable through solvent adhesives or 2-component adhesives; TPS types adhere well to PE, PP, PS, ABS, PA, PPE and PBT in so-called hard-soft combinations (multi-component injection molding)
