Advanced Vacuum Insulation Panels For Wide Range Of Markets

A vacuum insulated panel (VIP) is a new form of thermal insulation following the adiabatic principle for insulation. As a special composite made of core materials and protective layers, it is integrated with the superiority of vacuum insulation and micro-pore heat insulation, effectively stopping convective heat transfer to perfect its thermal insulation. With a thermal conductivity of as low as 0.0015w/m.k to 0.0025 W/m. K, the thermal resistance of our vacuum insulation panel is ten times higher than those conventional insulation materials and even more. Compared with traditional PU insulation materials, vacuum insulation panel, both energy-saving and environment-friendly, contains no ODS (ozone depleting substances) in its process of manufacturing. It is also regarded as advanced high performance insulation material.

Vacuum insulated panel has been widely applied to various thermal insulation products such as refrigerators, freezers, refrigerated trucks, cold storages, insulated shipping containers, ice storage tanks, etc. Through increasing the degree-of-vacuum of vacuum insulated panel to the limit, these thermal insulation products have a high-performance insulation and energy saving effect. With the upgrading of insulation material, vacuum insulated panel has achieved a great development. It can halve the energy and electricity consumption with half-thickness. Today, in keeping with the trend of CFC-free thermal insulation products in the future development, vacuum insulated panel, featured with energy conservation and large volume in a thin design, has been widely applied to refrigerators.

Core material

As a kind of filling material of vacuum chamber, core material has an influence on the initial thermal conductivity and lifespan of vacuum insulated panel. Fiberglass core material and fumed silica core material are the two commonly used materials. The former one has a lower thermal conductivity while the latter ensures higher reliability and longer service life.

Absorbent material

Absorbent material will react with the gas in vacuum chamber such as the active gas including nitrogen, oxygen, vapor, hydrogen, carbon monoxide and carbon dioxide for chemisorption, the adsorption of vapor in particular.

Barium-lithium alloy based getter material and CaO desiccant has been often used in VIP industries. Allowing a large amount of adsorption and enough stability, these high performance getters and desiccants are all for our independent research and development production, able to maintain the high degree-of-vacuum of vacuum insulation panel and prolong the using life of it.

High performance composite barrier film

High performance composite barrier film can effectively reduce the thermal conductivity of vacuum insulation panel at the edge effect to ensure the longer service life and lower thermal conductivity of VIP.
