Problems solved by technology

EPS, XPS, and PU are all organic thermal insulation materials. The biggest advantage is light weight, heat preservation, and good heat insulation; the biggest defect is fire prevention, poor safety, easy aging, easy to burn, large smoke, high toxicity, and low load-bearing capacity when burning. , service life, and fire resistance are not as good as inorganic insulation materials
