Original product description
This nonwoven waterproofing membrane is a roll-form underlayment intended for roof waterproofing. The stated three-layer construction consists of a polyester-coated body coated with SBS-modified bitumen and PP fabric on both sides. Its black top surface is UV-treated, and the longitudinal joint is self-adhesive.
Reported test data includes breaking strength above 55 lbf/in under ASTM D146, permeability of 0.05 perms under ASTM E96, and a net mass of 420 g/m² under ASTM D5261.
The membrane is also reported to pass cold-flexibility testing at -25°C for six hours under D5147, dimensional-stability testing under ASTM F1087, pliability testing under ASTM D146, and nail-sealability testing under ASTM D1970-15.
Additional listed values include tensile force of at least 600 N, elongation of at least 40%, and a stated temperature range of -40°F to 240°F. The source information lists ISO, MSDS, and CE certification and states that customization and ODM services are available. The stated minimum order quantity is 825 m².
Buyers should confirm the exact roll dimensions and coverage before ordering because the available data lists both 37.25 in × 145 ft and 1 m × 20 m, while also stating an area of 4.5 squares. Confirm which configuration applies to the quotation.
Procurement teams should also request the applicable certification documents and test reports, verify whether the reported properties apply to the selected customized construction, and agree on packaging, order quantity, lead time, installation requirements, exposure conditions, and warranty terms before purchase.
