  • Publication number: 20250215186
    Abstract: A method for preparing a recycled plastic includes the steps of: (a) mixing a waste plastic with a depolymerizing agent, followed by subjecting the waste plastic to a depolymerization reaction, so as to obtain a depolymerized product; (b) mixing the depolymerized product with a first polyether polyol to obtain a first mixture, followed by subjecting the first mixture to a polymerization reaction, so as to obtain a polymeric diol mixture; and (c) mixing the polymeric diol mixture with a second polyether polyol, a multi-functional isocyanate, and a solvent to obtain a second mixture, followed by subjecting the second mixture to a reaction, thereby obtaining the recycled plastic having a carbamate group. A recycled plastic prepared by the aforesaid method, a non-porous film or a microporous film obtained from the recycled plastic, and a composite fabric including the non-porous film or the microporous film are also provided.

  • Publication number: 20250058286
    Abstract: A moisture-permeable composite membrane is manufactured by the step of subjecting a mixture to a crosslinking treatment. The mixture contains a polyisoprene, a polyurethane with a polar functional group, a crosslinking agent, and a vulcanizing agent. In the mixture, a weight ratio of the polyurethane with the polar functional group to the polyisoprene ranges from 1:0.55 to 1:6.60. A method for manufacturing the moisture-permeable composite membrane is also provided.
