Jan 21, 2017

Polyethylene polypropylene fiber composite waterproofing membrane with polyethylene resin waterproof layer, double surface polypropylene filament nonwoven fabric reinforcing layer, using hot-melt pressure process a composite molding (low level products using quadratic compound forming process).

Main water-proof polyethylene film with excellent puncture resistance of linear low-scale polyethylene (LLDPE) resins manufactured by, while adding accessories to improve the coil primary water-proof flexibility and adhesion, added carbon black, antioxidants to improve membrane layer anti-aging.

Surface enhanced layers using the new polypropylene filament hot spun-bonded non-woven fabric, the main role is: one is to increase the core layer (water-proof) the overall tensile strength, core thickness reduced; the second is to increase the core layer of the surface roughness, play a protective role of the core layer; third, provide bonding structure of areola.

For surface enhanced layers of non-woven composite material structures, about 40% thick with impermeable polyethylene resin after hot melt glue, guarantee firm in conjunction with impermeable surface layer about 60% provided the thickness of coil layer adhesive layer bonding and structure, ensure the adhesive bonded fully with the impervious, waterproof tangential impervious structures.
