Oxidized Bitumen grades are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumen, and enables the product to serve a variety of uses in industrial applications. These grades are suitable for sealing saw cuts and joints where there is expected to be the minimum amount of moving in the joint. Their wide temperature range prevents bleeding in high temperature applications. They can also be used for industrial applications such as pipe coating, roofing, waterproofing, flooring, mastic, sound damping, carpet backing, adhesive and electrical applications.
Hard bitumen under controlled temperature conditions is widely used as an anti-slip layer compound in the piling industry, for manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts and under carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound and many others. Also used in sealing saw cuts and joints where expected movements are minimum.
Oxidized Bitumen 115/15 is petroleum bitumen. It made by blowing bitumen 60/70 by hot air. 115/15 is most popular grade (70% of our capacity).
