What is a composite aluminum foil molded poly vinyl foam board, and what is a composite aluminum foil extrusion poly vinyl vinyl insulation board, the two how to distinguish?Please try to be more specific
A kind of composite heat preservation board with aluminum foil is used in air conditioning and air duct insulation1, the insulation material molded type insulating materials used is moulded polystyrene foam board, also known as EPS, commonly used household appliances packaging materials is the white foam foam board; the extruded insulation material is extruded polystyrene foam board, which is XPS.
2, insulation performance EPS 0.041, XPS 0.030, indicating that in the same thickness, XPS insulation performance better, or to achieve the same insulation effect, thinner thickness3, water absorption rate EPS, water absorption rate is higher than XPS, XPS almost no water absorption
5, flame retardant properties of EPSXPS can reach B1 B26, the price of EPS is lower than XPSConclusion, if used in air conditioning, air duct and so on, XPS is superior in performance analysis,
