Hot Melt Adhesive for AL/PE Composite Pipe (BC-3A)

■ Characteristic
BC-3A is a multicomponent compound, the major component of which is Polyethylene grafted with maleic anhydride. It is a kind of hot melt adhesive especial for butt weld PE(PEX)/AL/PE(PEX) composite pipe. Possessing good physical and mechanical property, fine chemical and age resistance, and good processing performance, BC-3A can bond firmly to polyethylene, aluminum and iron, etc.
