■ Characteristic
PC-3H is polyethylene grafted with maleic anhydride and is a kind of adhesive polyethylene resin especial for AL/PE(PEX) composite pipe (overlapped welded). PC-3H can keep good resistance to chemical solvents and to weather, good processing and mechanical performance of polyethylene, at the same time, it also has fine cohesive property and can bond firmly to polyethylene and metals such as aluminum, iron, lead, etc.
