Polymer Modified Bitumen (SBS、APP)

Brief Introduction

Polymer Modified Bitumen waterproof membranes are composed of reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material. The kind roof systems typically are installed as a two-ply system and almost always are fully adhered.

Surfacings for modified bitumen membranes include aggregate surfacing, mineral surfacing, metal foil-laminate surfacing and smooth liquid-applied surfacing.

Polymer modified bitumen or modified bitumen sheet membranes were developed in Europe in the early 1960s and now have been widely in use all over the world.

There are two types of modified bitumen waterproof membranes:

·         Styrene-Butadiene-Styrene(SBS) polymer-modified bitumen membranes commonly are installed in hot moppings of asphalt or cold adhesive. SBS is a rubber-type modifier that gives bitumen the ability to stretch and resist damage, and improves its cold-temperature flexibility. Some SBS modified membranes are self adhering; that is, they contain an adhesive backing.

·         Atactic Polypropylene (APP) polymer-modified bitumen membranes typically are heat-welded or torch-applied. APP is specially suitable for high temperature and strong sunshine area.

Generally, APP modifiers impart a "plasticized" quality to asphalt, and SBS modifiers impart a "rubberized" quality to asphalt.

KRS Modified Bitumen waterproof membranes are ideal choice for the customer due to the following advantages.

Firstly Excellent durability and high strength. Glass-reinforced polyester, combined with pinpoint asphalt/polymer blends, provides puncture-resistant strength. The resulting elongation and recovery characteristics also resist stress and enhance the roof’s long-term performance.

Secondly Simple, economical installation. KRS Modified Bitumen waterproof membranes can be installed without extra time or money, thanks to installation options such as cold-applied adhesive; hot asphalt; heat-welded; self-adhered base with heat-welded cap; and mechanically attached base with heat-welded cap.

Thirdly Diverse choices for design freedom. KRS Modified Bitumen waterproof membranes are available in both SBS and APP. Our careful blending of polymers and asphalt results in a versatile product— giving the architect, contractor and building owner the ability to create a customized roofing solution.

At last Dependability in all applications. KRS Modified Bitumen waterproof membranes are ideal in any situation, from new roofing or reroof applications.
