Thermoplastic elastomers (TPE) are a group of materials that exhibit similar properties to rubber elastomers at room temperature, but can be plastically deformed when exposed to heat. Accordingly, the decisive technical feature of a TPE is its Shore hardness, which can range from 5 Shore A to 75 Shore D, depending on the material.
Advantageous properties of TPEs are the easy thermoplastic processing and the service temperature from -50 °C to +120 °C. They are suitable for blow moulding, extrusion and 2C injection moulding in applications with hard/soft combinations, e.g. with PA 6, PA 6.6, ABS, PP, PC and PC+ABS. Some TPEs also have good resistance to chemicals, oils and alkalis.
Types of TPE and Their Applications
There are a large variety of TPE grades, which are generally divided into block copolymers and blends.
• Styrene block copolymers (TPS)
• Urethane-based thermoplastic elastomers (TPU)
• Thermoplastic copolyamides (TPA)
• Thermoplastic copolyesters (TPC).
Blends are mixtures of complete polymers. These olefin-based thermoplastic elastomers can be crosslinked (TPV) or non-crosslinked (TPO).
Thermoplastic elastomers are used in a wide variety of areas – from household appliances, consumer electronics, mechanical engineering and construction to the automotive sector. Applications in this area stand out because around 36% of all TPE products worldwide are processed in the automotive industry. In the interior, they are used to make inlay mats, oversprayed handles and buttons for a better feel, as well as panelling and airbag covers. In the exterior area, TPEs are made into seals, spoiler lips or dirt traps, while in the engine compartment they are used for air ducts, dampers and oil sump seals.
