Product Description:

 Ultralow Temperature Elastomer (SBS) Modified Bituminous Waterproof Sheet Material is a 

thermoplastic and elastic modified bituminous dipping and coatingmaterial made out of Stylene-Butadiene-Stylene, it is a kind of rollable sheet water proof materials with the upper surface cover of the isolating materials like polyethylene film, fine sand or mineral slice (or particle) etc.

 
Type and Specification

·The physical and mechanical properties were divided in
Type Ⅰ and Type Ⅱ .
·Classified by upper surface isolating material: Polyethylene
film (PE), fine sand (S) and mineral particle (M). See below
table for detailed specifications.

 

Advantages

·Excellent ultralow temperature resistance performance, good
flexibility even under -40℃ , adapted to chilly region.
·The combination of filament polyester filler base and SBS
modified bitumen, forming a high strength water proof layer, to have
strong resistance agaist water pressure.
·High tensile strength, high elongation, it is adaptive to shrinkage,
deformation and fracture of base.
·Good resistance of high temperature,is able to meet the need of
various seasaons.
·High strength polyester filler base material has large thickness,
resistance of puncture, breaking, tearing and resistance of fatigue.
·Good performance of resistance to corrosion, mould and
weather.
·Good workability, we may construct by hot melt cementation
method during four seasons in the whole year, hot-joint is durable
and reliable.

Application Range

Applied in Grade Ⅰ and Grade Ⅱ water proof engineering in
various industrial and civil sections, be mostly appropriate to the
following engineering:
·Various industrial and civil construction roof and underground
water proof in chilly region.
·Indoor swimming pool and fire pool water proof of industrial and
civil construction.
·Water proof for municipal engineering such as subway, tunnel,
concrete road surface, bridge surface, sewage works and refuse
landfill etc.
·Water proof for water conservancy facilities like canal and water
pool etc .

Q:What is the difference between polymer waterproofing membrane and cross film waterproofing membrane?
he strong cross-over film of the product is a high-strength HDPE film formed by the cross-laminating process. The film and the like have the same vertical and transverse elongation ratio. The coil does not send deformation, more beautiful and waterproof reliable.
Q:Asphalt composite tire flexible membrane is SBS
The normal SBS membrane is in the high-grade waterproofing membrane, and asphalt composite tire flexible waterproofing membrane is a low-grade materials, the national industrial policy will soon stop its application in the field of engineering.
Q:The shortcomings of polypropylene waterproofing, and the shortcomings of modified asphalt waterproofing membrane
Waterproofing membrane in the waterproof construction in accordance with the shape of the waterproof base of the bulk of the truncated, for the complex shape of the grassroots need to multi-block splicing, waterproofing membrane overlap at each other more difficult, due to the impact of multi-block splicing waterproof Layer of beauty; then completely completely sealed will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with decades of durable durability,
Q:What are the requirements for the storage of waterproofing membranes?
Prohibited sun exposure, exposure easily deformed.
Q:SBS waterproofing membrane how to sample
EPDM membrane, rubber waterproofing membrane: the same manufacturers, specifications are not more than 5000m2 for a group, each batch of 2m2 Rubber water stop: the same manufacturers, specifications taken 2m long Modified asphalt polyethylene tire waterproofing membrane: the same specifications are not more than 1000m2 for a group, each batch of 1 volume
Q:PVC waterproof membrane effect how
4, hot-melt method: the use of flame heater melting hot-melt waterproofing membrane at the bottom of the hot melt adhesive bonding method of construction.
Q:SBs waterproof cold sticky how to do?
5, protective layer construction. In order to shield or reflect the sun's radiation, to extend the life of the waterproof layer of the membrane, in the waterproof layer is completed and checked after passing, should be coated on the surface of the waterproof layer of adhesive, side of the expansion of the expansion of silica powder protective layer, or uniform Brush the silver or green paint as a protective layer.
Q:Asphalt waterproofing membrane and polymer waterproofing membrane
It is a kind of self-adhesive polymer with self-adhesive function, such as butyl rubber and anti-sticking layer, which can be compounded with a certain thickness of the modified asphalt waterproofing membrane. Modified asphalt waterproofing membrane.
Q:What are the advantages and disadvantages of waterproofing membrane?
The waterproof membrane study its drawbacks: waterproofing is performed when the amount of coating material according to the cross-sectional shape of the waterproof base waterproof construction, the need for a complex shape of the base layer a plurality of splicing, waterproofing overlap each other at the bonding difficult than Large, due to the impact of multi-block splicing waterproof layer of beauty; then completely absolute seal will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with a few decades durable for a long time, but the country is still less matched the binder, and the binder material itself due to environmental factors such as loss of adhesion is often ahead of function, thus leading to the failure of the waterproof self-evident; Furthermore Waterproof membrane after the construction of the protection and leakage after the maintenance is also a problem, exposed waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and the grass-roots bonding, whether full of shops, shop, shop air, between the base layer and the web would be to go aqueous layer, regardless of any part of the cross-cutting breakage, degumming, drooling (even the only one), the entire coherent thereto waterproof power level Will lose all bad, if you can not find damaged and defective parts, the local repair is not possible, then only redo waterproof layer.
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
2, the insulation layer can be done on the waterproof above, according to the nature of insulation materials, insulation layer and waterproof layer can be set between the isolation layer or not set. If the waterproof layer on the laying of polystyrene foam board, do not need to do isolation layer; if the block of inorganic insulation materials, such as foam glass, waterproof layer should be set on the cement mortar protective layer; if the waterproof membrane to do Foam concrete or polyurethane block insulation, you can dry in the coil a linoleum for the protection of the isolation layer.
