Used for building insulation tiles and other steel and aluminum composite polymer bonding film products. Heat insulation color steel plate (color aluminum plate), it is color steel plate or galvanized plate as the substrate, with aluminum foil on the surface of the substrate, and the aging resistant polymer bonding film and color steel plate surface high temperature composite, so that the peel strength of each layer is more firm, to meet the outdoor use for many years is not easy to peel layered.

The above is the test data, only for reference, no production quality commitment
