Oxidized Bitumen 95 25, Softening Point 90/100 A C Application: Commercial

Petroleum asphalt is oxidized and then converted into oxidized bitumen 95 25 without adding catalysts. The material obtained from such processes has a much higher penetration index because it is done at high temperatures. It is used to bond roofing membranes.

The petroleum bitumen 95 25 is produced by blowing bitumen 60/70 with high temperatures and is composed of petroleum bitumen. 95 25 is the designation of the semi-softening point acceptance criteria for oxidized bitumen.

Bitumen oxidized undergoes a chemical reaction such that it turns from a solid to liquid after heating. In contrast, oxidized bitumen grades are created by passing a controlled amount of air through soft bitumen while under temperature control. Compared to penetration and hard grade bitumens, this bitumen has more rubbery properties, and it is utilized for a variety of industrial applications.
