(1) It has a unique micro-closed-cell honeycomb structure, which has the characteristics of high density, high compression performance, low thermal conductivity, low water absorption, and small water vapor permeability coefficient compared with EPS sheets. In the long-term high humidity or water immersion environment, XPS board can still maintain its excellent thermal insulation performance. Among the various commonly used thermal insulation materials, it is the only thermal resistance retention rate of 80% or more after two years at 70% relative humidity. Insulation material. (2) Due to the low long-term water absorption of the XPS board, it is especially suitable for inverted roofing and air conditioning ducts. (3) It also has good freeze-thaw resistance and good compression creep resistance.
