FLEX-MEND BB-1680 Mobile Flex Bottom Board Material – 16 ft. x 80 ft.

Mobile Flex is a special bottom closure, woven from black high density polyethylene and extrusion coated with a continuous layer of low density polyethylene. The material is uniform in quality with no weak spots. Its beach puncture resistance is more than five times the minimum established by HUD! Staple hold out is excellent. Penetrations and cuts will not spread and can be easily patched using V.P. Products & Sales’ FLEX-MEND tape. Mobile flex is totally impervious to water. Its strength can not be adversely affected by moisture. Because of its black polyethylene coating, Mobile Flex qualifies as a vapor barrier.
