PE roll size : The finished size for each roll of 4m x 50 meters 4mx100Meter +-1%
Material: made of woven high density black polyethylene(HDPE) fibers, warp xweft, laminated on both sides with low density polyethylene (LDPE)coating.
Material weight: minimum 190grm/m2 +-20grm/m2
Tensile strength: minimum 600N both directions of warp and weft (BS 2576, 50mm grab test, or equivalent).
Tear strength: minimum 100N both directions (BS 4303 wing tear or equivalent) or under ISO 4674 (A2)
UV Resistance: stabilized against ultraviolet rays and excess heat for long outdoor exposure. Maximum5% loss on original tensile strength under ISO 1421 after 1500 hours UV under ASTM G53/94 (UVB 313 nm peak)
Welding: only one(01)is allowed along the middle of the sheet, length wise . Minimum resistance is 80% of the original tarpaulin tensile strength in the weft under ISO 1421 plus additional procedure.
Flammability: flash point above 200 degrees C.
Color: white sun reflective on both sides, inner black fibers to ensure opacity
