Fire retardant (optional), waterproof, rotproof and UV-stabilised
Band reinforced tarpaulin in 4 m x 6 m sheets or 4 m x 60 m rolls developed by international research project and designed for long outdoor use in all climates
Woven high density polyethylene (HDPE) black fibres fabric laminated on both sides with low density polyethylene (LDPE) coating
Woven HDPE black fibres fabric, double-side lamination with LDPE coating, reinforced with six bands of 75 mm width woven black HDPE fibres fabric and coated outside. Pre-punched 8 mm holes on the two side bands at 0.1 m +/-10% intervals, positioned in the centre of the bands (only the reinforcement bands are pre-punched, not the tarpaulin itself).
Tensile strength
Min 500 N, 15-25% elongation in warp and weft in plain sheet under ISO 1421-1
UV resistance
After 1500 hours UV under ASTM G53/94 (UVB 313 nm peak) minimum 80% of original value of the actual product and not less than 475 N
Reinforcement bands
Min 700 N as per ISO 1421-1, pulling lengthwise in a prepunched 8 mm hole with a hook of 8 mm wire diameter, at 200 mm from the end of the band. UV resistance 80% of original value and not less than 665 N.
Welding
Only one is allowed, lengthwise. The tarpaulin tensile strength crossways at the place of welding under ISO 1421-1 minimum 50% of original value and not less than 400 N
