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.

Abstract: A heat-insulating transparent PVC sheet is formed from a PVC substrate having a thickness of 0.02-2.0 mm and contains heat-insulation pastes evenly distributed over the PVC substrate, since the heat-insulation paste contains an essential component of wolfram cesium powder (WCs) with a chemical formula of CsXNYWO3-ZClC and having a particle size of 0.005-2 μm, the heat-insulating transparent PVC sheet has an excellent weatherability, and particularly before and after tested in 300-hour service life in line with ASTM G-154 specification, has a physical property of weatherability decay rate (%) small than 4%.
