Product Description

Single-ply pvc waterproof membrane homogeneous non-composite membranes (pvc-h) products description the pvc waterproofing rolls formulas are based upon polyvinyl chloride resin with other assistants added to provide flexibility and stability such as anti-oxidant,absorbent of ultraviolet light, plasticizer and plastic filling agent. pvc waterproofing membrane is a highly-engineered,new-type membrane manufactured using polyvinyl chloride as main materials and added other chemicals such as anti-oxidant,anti-uv materials to make it flexible,stable and uv-resistant. product features 1. excellent weathering characteristics, 2.high tensile strength and long-term flexibility. 3. excellent resistance to harsh chemicals and industrial pollutants. 4.heat or solvent-welding effectively provides seamless roof coverings 5.can be choice for various methods of attachment and any shape of roof products specification name thickness(mm) width(m) length(m) pvc-h 1.2-2.0 2 20 technical parameters gb12952-2010 no. test item indicators h l p g gl 1 the thickness of resin layer above the reinforcement fabric mm= — 0.40 2 stretching performance maximum tension n/cm = — 120 250 120 tension strength mpa= 10 — — 10 — max. tension elongation %= — — 15 — — breaking elongation%= 200 150 — 200 100 3 heating treatment size change rate%= 2.0 1.0 0.5 0.1 0.1 4 low-temperature bending -25? -25? no craze 5 water impermeability water impermeability 6 impact resistance water impermeability 7 anti-static load a — — water impermeability 8 seam peel strength n/mm = 4.0 or membrane breaking 3.0 9 right-angle tear strength n/mm = 50 — — 50 — 10 trapezoid tear strength n= 150 250 220 11 water absorption(70?168h)% after soaking = 4.0 after airing= -0.40 12 heat aging(80?) time 672h appearance no blisters, cracks, delamination, bonding and holes tensile strength (max. tensile)retention%= 85 elongation retention %= 80 cold bending no craze 13 chemical resistance appearance no blisters, cracks, delamination, bonding and holes tensile strength (max. tensile)retention %= 85 elongation retention %= 80 cold bending no craze 14 artificial climate accelerating ageing c time 1500hb appearance no blisters, cracks, delamination, bonding and holes tensile strength (max. tensile)retention %= 85 elongation retention ?= 80 cold bending no craze a anti-static loading is only applied to the roofing membrane. bthe artificial climate accelerated time is 2500 hours for single roofing membrane. c artificial climate accelerating ageing test is only apply to exposure membrane. application range pvc waterproof membrane forms an effective barrier to liquid water or water vapor in the steel structure for industrial and civil engineering, underground engineering, such as sub
