The STP use a high-strength composite gas barrier film made from multiple layers, the film has a very good gas barrier properties, Ventilation amount is less than 3.56 gram per square meter in 60 years by test calculation. If placing about 25 gram metal matrix composite getter in STP panel, the permeated gas would be absorb completely, and the internal pressure could be control less than 10 pa in 60 years, Under this condition, thermal conductivity of STP will not change basically.
     Vacuum Insulation Panel, called VIP panels for short, is the most efficient insulation materials at present, which is prepared by a special filling material , getter and protective film can block gas leakage. Due to the internal core material with low thermal conductivity, and the extremely low degree of vacuum, So the product can significantly affect the heat conduction and convection, which make the product having a very good thermal insulation, thermal conductivity can be reach 0.0040w/m. k or less. Under the same conditions, the insulation effect is 5 ~ 7 times than polyurethane material.
    This product enables the refrigeration system to save energy by 50%, and to increase storage space by more than 10%. Due to low product density, product which used VIP can significantly reduce the weight. VIP production and it's application process does not use any ODS substances, so it has the dual effect of environmental protection and energy conservation.
    Because of its superior insulation properties, vacuum insulation panels can be widely used in refrigerators, freezers, refrigerated trucks, cold storage, refrigerated containers, ice storage tank, water heaters, LNG storage, refrigeration and other medical products or fields.
