TPU, a material, many possibilities

A material of excellence

TPU are thermoplastics elastomeric which combine elastic properties of elastomeric and mechanical properties of plastics. This material is very resistant to abrasion,  it can be combined with other materials, and it is recyclable.

We are known for our experience and our expertise of the product. We are transforming more than 100 tons of this material each year. Auray Plast designs and produces technical plastic parts meeting to very strict specifications regarding the respect of dimensions and geometry.


At Auray Plast, we transform TPU by injection. It means that we melt pellets which are die-cast in steel moulds. It can ensure us to make practically any parts in our factory. We have 25 injection moulding machines from 30 tons to 350 tons. All of them are recent, and a majority are electric for more precision and cleanliness.

We are answering with our engineer office to all your demands requiring specialists of these materials.

For which applications?

IWhere can we find TPU ?

We can find TPU in many daily products.

A few auto parts, exterior or interior.

Sports articles, like shoes, ski boots, scuba diving masks, or swim fins.

In hydraulic cylinders, which a large portion of seals are made in TPU.

Where can I find the TPU?

In the medical field, they are used for infusion or draining systems, in equipment like prosthetic legs or medical bed wheels.

The cell phone protective covers may also be in TPU.

There are also TPU in electric or electronic connectors.

At last, we are using TPU in many sealing systems

Advantages of TPU

Relative to rubber, TPU have several advantages :

  • A best resistance to abrasion,
  • Best resistance to scratches,
  • An easy coloration,
  • Recyclability,
  • Greater diversity of parts shape,
  • Transparence.
