Hot Melt Adhesive for AL/PE Composite Pipe

is polyethylene grafted with maleic anhydride, which is a kind of adhesive polyethylene resin especial for PE(PEX)/AL/PE(PEX) composite pipe (overlapped welded). BC-1 keeps the good properties of polyethylene such as good resistance to chemical solvents and to weather, good processing and mechanical performance, at the same time, it also has excellent adhesive property and can bond very firmly to polyethylene and metal such as Aluminum, iron, lead, etc. Typical Property Data Performance Testing method Unit Index Appearance Visual Examination Milk white equal pellets Density GB1033-86 g/cm3 0.935 Melt Flow Rate GB3682-89 g/10min 4-6 Tensile Strength at Break GB1042-92 MPa ＞15 Elongation at break GB1042-92 % ＞800 Charpy Impact Strength GB1843-96 kJ/m2 unbroken Shore Hardness D-scale ＞50 Vicat Softening Point GB1633-79 ℃ >105 Melt point ℃ 132
the hot-melt adhesive especial for PE(PEX)/AL/PE(PEX) composite pipe (overlapped welded) and is suitable for co-extrusion processing. Suggested extrusion temperature from feeding zone to die: 180℃, 200℃, 220℃, 230℃. It can also be used as the corrosion pr
