Description
Thermoplastic elastomers (TPEs) are polymer materials that combine the elastic properties of rubber with the melting and moulding properties of thermoplastic plastics. They are flexible and stretchable at ambient temperatures, and can be easily recycled and reprocessed under heat.
Properties and features
They can be significantly stretched and return to their original shape, similar to traditional rubbers.
They remain flexible at room temperature, even after significant deformation.
TPEs have good wear resistance, making them durable in applications subject to friction.
They retain their elasticity over a wide range of temperatures, but can soften and melt at higher temperatures, making them easier to mould.
They can soften under the effect of heat, allowing reversible shrinkage and deformation without deterioration.
They are generally resistant to many chemicals, oils and solvents, making them useful in a variety of environments.
TPEs often have a low water absorption capacity, making them suitable for applications where humidity is a factor
They can be transformed by common plastics processes such as injection moulding, extrusion and thermoforming.
TPEs can be recycled and reprocessed several times without significant loss of mechanical properties
