Problems solved by technology

Polystyrene (EPS/XPS) foam thermal insulation material is a thermoplastic material, which has the characteristics of light weight, good processability, good compactness, and good thermal insulation effect. It has superior performance than inorganic thermal insulation materials, but in Some of its shortcomings are gradually exposed during use: EPS/XPS insulation materials have a cavity structure, and the outside air is easy to flow through the gaps in the cavity and affect the heat insulation effect; poor wind resistance: the tensile strength of EPS is lower than that in dry conditions. , is only 0.1Mpa, and the tensile strength after immersion in water is lower, so EPS is generally not used in high-rise buildings;
