It can be injection molded by general injection machine and can be recycled and processed. Its processing and product characteristics are far superior to the traditional non-environmental thermosetting properties that cannot be recycled and low vibration damping. rubber. [Prior Art] Vibration and noise are long-standing problems with human beings. As industrial development, processing precision, safety and comfort requirements increase, vibrations and problems become more and more important, and noise problems mostly originate from vibration. Therefore, noise and vibration tend to expand to affect the comfort level, so there is a need to reduce the vibration from the source; for example, from the basics of construction, transportation equipment, electrical appliances, sports equipment, office equipment and personal information equipment, Everything related to human activities has the effect of suppressing noise and noise. Traditional cushioning materials such as silicone rubber (SILICONE), EPDM, NBR, etc. have poor vibration-making functions. Even rubbers with high damping values such as IIR must be treated by thermal hardening or thermal cross-linking. Both the product and the edge material are not recyclable, energy-consuming and environmentally friendly. Generally, the thermoplastic elastomer has low damping value and no vibration-damping effect.
