Ultrafine Glass Fiber Core Material Produced by Wet Method

Glass fibers have non-flame, non-toxic, antisepsis, light volume-weight, low heat conduction factor, good chemistry stability, low water absorption coefficient and good hydrophpbic coefficient. In this paper, ultrafine glass fiber core material was produced by wet method. Performances of ultrafine glass fiber core material and VIP were introduced. The thermal conductivities of ultrafine glass fiber core material is about 0.02966 W/(m•K). Ultrafine glass fiber core material with about 92%-98% porosity ratios makes it easy to reach high vacuum degree for VIP. The thermal insulating capacity of VIP is about 10 times higher than that of conventional insulating materials. Ultrafine glass fiber core material is ideal core material for VIP.
