Rainshield range of Hi-performance membranes are manufactured with selected bitumen, APP and other polymers. The unique nature of this closely guarded technology involving processing at low temperatures affords protection to the polymers in the blend with the result the product is tough yet flexible. The blend of APP and other polymers imparts high chemical resistance and retards the process of aging associated with Ozone attach and UV exposure while at the same time retaining all the mechanical properties.
