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 
 

Technique data

There are two methods in application:
(a)One way is by heating and melting method.Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted (not flowing),then install the membrane filly bonded to the roof deck with overlaps of 5-10cm.
(b)The other way is by cold adhesive method.Pour the cold adhesive homogeneously on the roof deck, then roll the membrane to install it to be fully sticked to roof deck.
(c)After application,a full serious inspection is required to sure no air bubble,no falling away.etc. to guarantee the waterproof life.
