Hot Melt Adhesive for AL/PE Composite Pipe(BC-2H)

■ Characteristic
BC-2H is polyethylene grafted with maleic anhydride, which is a kind of adhesive polyethylene resin especial for PE(PEX)AL/PE(PEX) composite pipe (butt welded). Possessing fine physical and mechanical property, good chemical and age resistance, and good processing performance, BC-2H can bond very firmly to polyethylene, aluminum and iron, etc.
