Description
Summary:A recyclable thermoplastic polyurethane (TPU)/Silicone thermoplastic vulcanizate (TPV) consisting of TPU, Silicone, and additives (i.e. crosslinking agent, antioxidant, compatilizers, and processing aid) with high tensile strength (10.0 MPa), good elongation (322%), low abrasion rate (0.11%), proper hardness (Shore A83), and low static/kinetic friction coefficient (0.72/0.61) has been successfully manufactured. Moreover, we have also prepared the prototype for bands of smart bracelets based on lab-made TPU/Silicone TPV, demonstrating that it is a highly potential recyclable material for wearable devices.
