Abstract: A breathable and waterproof membrane is made from a modified thermoplastic polyester elastomer. The breathable and waterproof membrane has a moisture permeability of greater than or equal to 25000 g/m2·day. The modified thermoplastic polyester elastomer is formed from a thermoplastic polyester elastomer, a regenerated polyethylene terephthalate, and a compatibilizer. Based on a total weight of the modified thermoplastic polyester elastomer being 100 phr, a content of the regenerated polyethylene terephthalate is greater than 0 phr and up to 50 phr. Based on a total weight of the thermoplastic polyester elastomer being 100 wt %, the thermoplastic polyester elastomer includes 25 wt % to 75 wt % of hard segments and 25 wt % to 75 wt % of soft segments.

Abstract: A recycled PET foam material and a manufacturing method thereof are characterized in that a recycled material can be used. The manufacturing method includes the following steps: uniformly mixing PET resin, chain extender, antioxidant, flame retardant and heat stabilizer, and then mixing with a twin-screw extruder to obtain a foam PET resin. The PET foaming material obtained is a material having the advantages of light weight, large rigidity, high specific strength, good electrical insulation, good sound insulation and the like, low raw material cost, simple manufacturing process and environmental protection.
