1. Thermal insulation performance: thermal conductivity of polyurethane is 0.022W/(m · K), EPS is 0.041W/(m · K), XPS is 0.028W/(m · K).2. Tightness: EPS and XPS are bonded with seams and cavities, and the external air can easily flow through the seams and cavities, affecting the insulation performance.If the factor that there are gaps in the cavity is taken into account
As a polymer material with excellent performance, polyurethane thermal insulation material has become the fifth largest plastic after polyethylene, polyvinyl chloride, polypropylene and polystyrene, and the global total output has exceeded 10 million tons/year.In recent years, China's polyurethane industry has made great progress, and has been widely used in refrigerator, container, leather, shoemaking, textile and other fields.Of course, in our
