Rigid polyurethane boards with moisture, water resistance. Closed-cell rigid polyurethane rate is above 90% fourth foam boxes, are hydrophobic material IV foam box outlets, will not absorb moisture increases thermal conductivity, walls are not seepage. Advantages of XPS: XPS board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the EPS same thickness, so it has a better than the EPS insulation properties. IV foam box production, Qu fourth foam boxes, foam plastic brand Zhucheng Yong Hua Hua Yong provided by Zhucheng Plastic Foam Factory.
