Hot Melt Adhesive for Steel/PPR composite pipe (BC-4HR)

Characteristic
BC-4HR is polypropylene grafted with maleic anhydride, which is a kind of adhesive polypropylene resin especial for STEEL/PPR composite pipe. BC-4HR keeps good processing and mechanical performance of polypropylene, at the same time, it also has excellent cohesive property and can bond firmly to polypropylene (PPR) and metals such as aluminum, steel, copper, etc.
