Hot Melt Adhesive for AL/PE Composite Pipe (828#)

■ Characteristic
828# is multicomponent compound, the major component of which is Polyethylene grafted with maleic anhydride. It is a kind of hot melt adhesive especial for butt welded PE(X)/AL/PE(X)  multilayer pipes. Possessing excellent physical and mechanical property, high chemical resistance and age resistance, and good processing performance, 828# also has excellent adhesive property and can bond very firmly to polyethylene, aluminum steel and lead, etc.
