Thermoplastic polyester elastomers (TPE-E) can be produced with different formulations, with properties ranging from softer to harder. Depending on the amount of of plasticiser used, such as polyalkylene glycol ether, Shore hardness values from D 38 to D 74 can be achieved. The service temperature of TPE-E is between 40°C and 120°C. Due to its excellent performance under dynamic loads, TPE-E is a popular material in special cable manufacturing. Its high resistance to alternating bending stress and its high impact strength are worthy of note, and its resistance to chemicals, oils and solvents is another point in its favour.
