| Message: | thermal insulation materials rock wool board is a kind of non-combustible product whose melting point is above 1000℃. Our rock wool batts is a inorganic substance without any nutrient, and will not rot or breed any pests, it is not attached by any micro-organism. Our stone wool mineral wool has features such as non-toxic, low thermal conductivity, hydrophobic, fireproof,sound-absorption, good physical and chemical stability. Doesnot use any CFC, HFC, HCFC or asbestos.PropertiesIndexUnitStandardThermal conductivity(Average temperature 25°C)≤0.040W(M.K)GB/T 10295Fire performanceNon-combustible-GB/T 8624-2012Acidity coefficient≥1.8-GB/T 5480Water repellence rate≥99%GB/T 10299Water absorption(Partial immerson) |
