The Polycryo ground sheet is constructed from industrial grade cross-linked polyolefin. This material is extremely tough for it's weight, with amazing puncture resistance. It has a tensile strength of 15,400 p.s.i. (1,083 kg./sq. cm.) per ASTM D-883. It is waterproof, but very slightly breathable (1.09 gms of water vapor/100 sq.in./24 hours). At 0.55 oz./sq.yd. (16 g.), it's HALF THE WEIGHT of Spinnsheet™ ground cloths. You will have to replace this more often than tougher alternatives, but it's very economical. These single ground cloths are shipped as a 2-pack so you have an extra. Our medium size is 40" (102 cm.) wide. Since these sheets are made from shrink film they will shrink when exposed to extreme heat. We tested these sheets in heat this summer and found that the sheets shrink 1" to 2" (3 to 5 cm.) in width and up to 5" (13 cm.) in length. These sheets do not need to be in direct sunlight to shrink, just very hot temperatures.
