TPE: What It Is, Properties and Applications | 2026 Guide

Written by Weerg staff | Apr 2, 2026

TPE (Thermoplastic Elastomer) is a class of polymer materials that combines the elastic properties of rubber with the processability of thermoplastics.
Thanks to this unique combination, TPEs are increasingly used in sectors such as automotive, electronics, consumer goods, medical applications, and 3D printing.

These materials enable the production of flexible, durable and recyclable components, while also offering ease of processing and competitive costs.

What is TPE

TPE is a thermoplastic elastomer, meaning a material that exhibits rubber-like elastic behaviour but can be melted and reshaped like a plastic.

Unlike traditional vulcanised rubber:

  • it does not require irreversible chemical processes
  • it can be remelted and reused
  • it can be processed using standard industrial methods

This makes it highly versatile and well suited to modern industrial manufacturing.

Structure of TPEs

TPEs are made up of two different polymeric phases:

  • an elastic phase (rubber), which provides flexibility
  • thermoplastic phase, which gives stability and processability

This structure allows the material to:

  • deform elastically
  • recover its original shape
  • be processed through melting

Main Properties of TPE

TPEs offer a well-balanced combination of properties:

Elasticity

They can deform and return to their original shape without permanent damage.

Flexibility

They remain flexible even at low temperatures.

Good impact resistance

They absorb energy without breaking easily.

Grip and adhesion

Ideal for non-slip surfaces and ergonomic handles.

Recyclability

As thermoplastics, they can be remelted and reused.

Good processability

They can be processed through:

  • injection moulding
  • extrusion
  • 3D printing
  • overmoulding

Types of TPE

The TPE family includes several materials, such as:

TPE-S (Styrene-based TPE)

Among the most common, used in consumer products and automotive applications.

TPE-O (Olefinic TPE)

Used in applications requiring weather resistance.

TPE-V (Thermoplastic vulcanisates)

Offer performance similar to vulcanised rubber.

TPE-E (Copolyester elastomers)

Provide good chemical and thermal resistance.

TPE-U

Includes thermoplastic polyurethanes (TPU), a subcategory with higher performance.

TPE Hardness

TPEs are available in a wide range of Shore hardness levels, which determine material rigidity.

Indicatively:

  • Shore A 20–40 → very soft
  • Shore A 50–70 → medium flexibility
  • Shore A 80–95 → more rigid

This allows the material to be adapted to many different applications.

Applications of TPE

Thanks to their versatility, TPEs are used across many industries.

Automotive

  • seals
  • coatings
  • anti-vibration components

Electronics

  • cables and coatings
  • flexible connectors

Consumer goods

  • ergonomic grips
  • sports equipment
  • soft-touch products

Medical

  • flexible devices
  • medical tubing

Packaging

  • elastic components
  • caps and closures

TPE in 3D printing

TPEs are also used in MJF and FDM 3D printing, especially when flexible parts are required.

Advantages

  • high flexibility
  • good impact resistance
  • vibration absorption

In many cases, TPU - a variant within the TPE family - is preferred due to its greater stability during printing.

Advantages of TPEs over traditional rubber

TPEs are gradually replacing some vulcanised rubbers because they offer:

  • simpler production processes
  • recyclability
  • reduced waste
  • overmoulding capability
  • lower production costs

Conclusions

TPE is an extremely versatile material that combines the flexibility of rubber with the processability of thermoplastic polymers.

Thanks to its elasticity, durability and recyclability, it is widely used across numerous industrial sectors and everyday products.

With the evolution of manufacturing processes and 3D printing, TPEs will continue to play an increasingly important role in the design of flexible and functional components.
