***Dura Skrim R20WW is manufactured with virgin resins. Only Virgin resins are used in the production of the Dura Skrim R Series (6-20 Mil). All resins used in the food contact layer are FDA 21 CFR 177.1520 (c) 3.2 compliant.***  DURA SKRIM R20WW consists of virgin outer layers of white high-strength polyethylene film laminated together with a black layer of molten polyethylene. Both outer layers contain UV inhibitors and thermal stabilizers to assure long outdoor life. The white layers are designed to reduce heat build up and condensation, and to provide excellent dimensional stability. A layer of polyester scrim reinforcement placed between these plies greatly enhances tear resistance and increases service life. DURA SKRIM's heavy-duty diamond reinforcement responds to tears immediately by surrounding and stopping the tear. R20WW is used in applications that require exceptional outdoor life and demand high puncture and tear strengths. Product is manufactured from a very chemical-resistant, virgin polyethylene and meets GRI-GM22 Standard Specification.   Product Highlights: • Scrim Reinforced for Durability • Waterproof and moisture blocking • Heavy duty puncture resistance for rocky and hard soils • FDA 21 CFR 177.1520 (c) 3.2 Compliant • UVI additives for extended lifespan   Common Applications: • Heavy Duty Crawl Space Liner • Vapor Barriers • Remediation Covers • Temporary Erosion Control • Lumber Covers • Shipping Covers • Pallet Covers • Cargo Wraps • Insulation Membranes • Building Enclosures • Concrete Curing Covers • Silage Covers • Temporary Walls • Fumigation Covers • Asbestos Abatement • Construction Site Covers • Aquaponics Liners, Grow Bed Liners, Trough Liners
