Description: |
|
Roofing membranes for low-slope application
are generally asphalt or polymer-based.
Bitumen has been used as a roof
waterproofing agent for many years. To make
bitumen tougher and more elastic, a
synthetic polymer is usually added. The
resulting mixture is called modified
bitumen. Modified bituminous sheets are made
by combining the modified bitumen with
reinforcements such as glass fiber and polyester
fibers.... |
|
|
|
>>
Applications: |
|
Two types of modifiers are commonly used
to produce roofing bitumen:
atactic polypropylene (APP) and styrene-butadiene-styrene (SBS).
SBS is a rubber-type modifier that gives bitumen the ability to
stretch and resist damage, and improves its cold-temperature
flexibility. |
|
APP modifiers impart a "plasticized" quality
to asphalt, and SBS modifiers impart a
"rubberized" quality to asphalt. |

Specification: |
| Kianco membrane is
a premium, fire-retarding modified bitumen membrane manufactured to
stringent specifications. Its core is a strong, heavyweight,
resilient non-woven polyester mat that is coated with an inherently
fire-retardant APP polymer modified asphalt and surfaced with
mineral granules. |
