VIP (основной материал)

Density:120-180 kg/m3 thermal conductibility:0.03-0.04W/m.K Average fibe dia.:2.5um(>40%) Temperature:<450 with aluminum foi Hongda Fangyuan Mico-glassfiber (1-5.5μm) is processed as raw material to produce VIP core filling by taking wet and dry technique. It’s one of the new type of high efficient insulation on material, with dozens of advantages like light weight, low thermal conductivity good, elasticity, non-toxic, no-flammable, anti-aging, chemical stability, non-polluting, easy construction and so on. Its thermal conductivity is very low under vacuum condition.
