■ Characteristic
BC-1 is polyethylene grafted with maleic anhydride, which is a kind of adhesive polyethylene resin especial for AL/PE(PEX) composite pipe (overlapped welded). BC-1 keeps good properties of polyethylene such as good chemical solvents resistance and weather resistance, good processing and mechanical performance, at the same time, it also has excellent cohesive property and can bond very firmly to polyethylene and metal such as Aluminum, iron, lead, etc.
