Thermoplastic Elastomers (TPEs), also known as Thermoplastic Rubber compounds, are unique materials that combine the elasticity of rubber with the processing ease of plastics. These versatile substances are composed of hard and soft phase systems, which can be structured as blends, alloys, or copolymers. TPEs find widespread use in applications where a ‘soft touch’ is desired, such as ergonomic grips on toothbrushes, or where flexibility is crucial. Their ability to absorb energy makes them ideal for acoustic or vibrational dampening purposes. One of the most remarkable features of TPEs is their adaptability – depending on the formulation, they can range from extremely soft, gel-like substances to hard, polypropylene-like plastics.
