■ Characteristic
BC-4H is polypropylene grafted with maleic anhydride, which is a kind of adhesive polypropylene resin especial for AL/PPR composite pipe. BC-4H keeps the good resistance to chemical solvents and to weather, and 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, iron, lead, etc.
