About Blown Bitumen 115/15:
By passing air through Bitumen penetration 60/70, Oxidized bitumen grades like Blown Bitumen 115/15 are produced. This process gives bitumen more rubbery properties. Also they are harder bitumen. Hard bitumen under controlled temperature conditions. We widely use that as an anti-slip layer compound in piling industry, for manufacture of roofing felts, roofing and waterproofing industries, sound dampening felts and under carriage sealant in automotive industry, electric cable joint protection, joint filling compound, sealant compound and more. Also we use in sealing saw cuts and joints.
In addition we use that in manufacturing of bituminous marine mastic for oil & gas pipeline joints.
Oxidized bitumen is a very flexible compound that is not only chemically stable but also a very durable compound apart from being completely water resistant. It`s highly flexible and durable. Furthermore, it`s chemically very stable.
Lastly, Oxidized Bitumen has some very prominent technical advantages that makes it a very sought after compound in various uses.
