What is TPE 

TPE stands for Thermoplastic elastomers.

TPE’s are a class of polymers that combine the characteristics of both thermoplastics and elastomers. Because of their unique characteristics, they can be very advantageous in terms of recyclability compared to certain other materials. TPE’s have the following key properties:

1. Thermoplastic Nature

TPE’s are thermoplastics. This means they can be melted and reshaped when heated and they solidify into a specific form when cooled. This property makes them highly versatile and allows for efficient processing methods, such as injection molding and extrusion.

2. Elasticity

TPE's have elastomeric properties, which means they can stretch and return to their original shape. This elasticity makes them suitable for applications requiring flexibility, resilience, and the ability to withstand deformation without permanent damage.

3. Softness and Flexibility

TPE's can be formulated to have a wide range of hardness and flexibility, from very soft and rubbery to harder and more rigid, depending on the specific application requirements.

4. Chemical & Weather Resistance

TPE's often exhibit good resistance to a variety of chemicals, which can be advantageous in applications where exposure to different substances is a concern. Furthermore TPE formulations are resistant to UV radiation and environmental factors, making them suitable for outdoor applications.

5. Cost-Effective

TPE's are generally more cost-effective than traditional elastomers, such as vulcanized rubber, and offer a balance between performance and cost.

6. Recyclability

Because of its versatility and it’s high compatibility with other plastics, TPE’s are an attractive option for environmentally conscious applications with a focus on recyclability.

There are seven generic classes of commercial TPE's together with multiple unclassified categories, each with its unique properties and advantages, making TPE's a versatile material for many different applications:

  • Styrenic block copolymers, TPS (TPE-s)

       → ​Used in applications like footwear and adhesives.

  • Thermoplastic polyolefinelastomers, TPO (TPE-o)

       → ​Used in applications like automotive bumpers, dashboards and other â€‹

  • Thermoplastic Vulcanizates, TPV (TPE-v or TPV)

       → ​Used in automotive seals, weather stripping and other demanding applications​

        → ​Used in applications such as hoses, tubes, power tool grips​

  • Thermoplastic copolyester, TPC (TPE-E)

       → ​Used in applications in demanding industries such as electronics and medical devices​

  • Thermoplastic polyamides, TPA (TPE-A)

        → ​Used in aerospace components​

  • Melt Processable Rubber (MPR)

       → ​Used in inflatable boats, seals, goggles,…​

While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection moulding or extrusion. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. On top of that, TPE's are 100% recyclable.
