2. Product description
Physical and chemical slab color is rich, have such as bright surface of dumb light of a variety of surface texture, its surface after the special chemical treatment has more powerful chemical resistance performance.
Physical and chemical slab is a kind of specially made for laboratory stage face plate, by more than 140 phenolic resin impregnated finest imported kraft paper.
Through special processing of decorative color paper, reoccupy etch steel at 150 ℃ high temperature 1430 psi high pressure environment, through melting and irreversible aging hardening of 60 minutes a integrated.
Comprehensive erosion resistance against acid and alkali, three levels of protective structure: 1. The Chemical membrane Chemical - resistant qualities.2. The color Paper Deco Paper;3. Special multi-layer Kraft Paper (Kraft Paper).
