SW531 Excellent insulation properties Polyurethane

Excellent insulation properties Polyurethane building insulation is the lowest thermal conductivity of the field of thermal

Polyurethane PERFORMANCEExcellent insulation propertiesPolyurethane building insulation is the lowest thermal conductivity of the field of thermal insulation materials, thermal conductivity of 0.018 ~ 0.024W / (m · k), is leading the field of foreign building insulation products, but also to achieve our target of 65% of building energy efficiency the best insulation products. Has the same insulating effect of the contrast of different material thicknessExcellent fire performanceThe company developed the production of modified polyurethane insulation core material, acetylene flame to burn through the test, the surface of a fire after the formation of carbonized coke layer, so that from the self-extinguishing fire, melt drip phenomenon does not occur, and no phenomenon of bubble collapse, the core material composed of fire insulation system can effectively suppress the fire spread, to avoid the ignition of other flammable materials, can well meet the requirements of building fire safety. Comparing various types of insulation core materialPerformance comparison of different insulation core material More content PU, EPS and XPS comparison Insulation Best PU, XPS Second, EPS ranking at the end Compressive strength XPS, PU is stronger than EPS Tensile strength XPS, PU better than EPS, XPS or PU at the top with more secure Water vapor permeability Water vapor permeability can reach the standard Water absorption Requirements can be achieved hydrophobic, EPS for the half-hole structure, water absorption, wet climate on the performance of EPS insulation to be significantly adversely affected Flame-retardant Can reach B2 level, but the XPS, EPS has droplet will lead to combustion Conclusion From the insulation and security, PU better than EPS and XPS
