SBS/APP Modified Bitumen Waterproof Membrane

SBS/APP modified bitumen membrane is a kind of flexible sheet waterproof which uses Styrene Butadiene Styrene/SBS  thermoplastic rubber OR amorphous polypropylene (APP) as a dipping and covering modifier,whose upper surface is coated by PE film, fine sand, mineralgrain or aluminum foil or other isolating materials.The compound is a mixture of distilled bitumen,plastomers and elastomers which gives the membrane excellent resistance to heat aging and weathering. 

Features:
(1)SBS/APP modified bitumen waterproof membrane
(2)conforms to the national standards
(3)embossed belt and PE waterproof membrane
(4)technique: spunbond
(5)length of roll
(6)core material:polyester mat or composite  mat

Characteristic: 
(a)SBS modified bitumen waterproof membrane is specially used as waterproof material in cold area
(b)APP is specially suitable for areas of high temperature and of strong sun-shine
(c)Good performance in Good impermeability anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering 
(d)Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack
