  • Patent number: 11759984
    Abstract: Provided is a damping pad with low compression set, which is prepared by a method comprising the following steps: (1) providing a polymer comprising a thermoplastic ether ester elastomer, in which the polymer material has specific melt flow index, Shore D hardness, tensile modulus, density, and elongation at break; (2) melting the polymer material to obtain a molten polymer material; (3) adding nitrogen gas or carbon dioxide into the molten polymer to obtain a mixture; (4) turning the mixture into a supercritical state and compounding the mixture, to obtain a supercritical fluid blend; and (5) injecting and molding the supercritical fluid blend to obtain the damping pad with low compression set which has compression set of 40% or less, deceleration value of 20 or less, and rebound resilience of 50% or more.
