Product Features:
This product is a kind of unbreakable asphalt waterproof cushion which belongs to the waterproof and wet isolation construction material area, it has excellent tensile flexibility.it is composed by the polymer felt, tensile layer and release layer. The bitumen compound layer is SBS modified bitumen compound layer or rubber bitumen compound layer.in order to solve the problem of easy breaking and weak tensile strength; we coat the felt layer with compound bitumen layer and tensile layer. We paint the mineral sand onto both side of the cushion to stop the stickiness. This tensile flexibility waterproof cushion is flexible, at the same time, it has excellent tensile strength, and it is waterproof and moist insulation,it has very long service time, its produce technology is simple and suitable for waterproof project of the base, floor and roof for all kinds of buildings.
Product Characteristic
1.High dosage SBS, ensure the long term service time.
2.Unique formula ensure the SBS have a good compatibility with the bitumen, it will grantee the stability and stickiness in long term service time.
3.Advanced produce technology and equipment can ensure the quality of membrane
Applicable scope:
Application range
1.Viaduct,bridge, underpass, tunnel,underground,park,air station
2.Flat roof, arch roof, cement preset roof
