Relief Tarpaulin

Plastic Tarpaulin Sheet (4×5 m) – Palletised / Non Palletised
Materia  
Material for the plain
sheet
Made of woven high-density black polyethylene (HDPE) fibers, warp x weft, laminated on both sides with low density polyethylene (LDPE) coating, with reinforced rims by heat sealing on all sides, (or 2 sides heat sealing and 2 sides double stitching), and a 5 millimetres diameter PE or PP rope on the edge, inside the hem. 1000 denier minimum.
Reinforcement eyelets Aluminium eyelets or equivalent on four sheet sides of the single sheetsat 100cm ±5cm centre to centre, providing very strong fixation points. 
Tensile strength Minimum 600 N both directions of warp and weft (BS 2576, 50mm grab test or equivalent).
Tear strength in plain sheet at state of origin Minimum 100 N both directions (BS 4303 wing tear or equivalent) or under ISO 4674 (A2).
Tensile strength of the eyelets Minimum 700N inside the eyelets as per ISO 1421-1, pulling lengthwise with a hook of 8mm wire diameter.
UV resistance Stabilized against ultraviolet rays and excess heat for long outdoor exposure. Maximum 5% loss on original tensile strength under ISO 1421 after 1500 hours UV under ASTM G53/94 (UVB 313 nm peak).
Central welding and strength
