Bitumen penetration grade 160/220

Bitumen grade 160/220 is a premium brand that is dark brown or black color similar to cement-shape semi-solid or viscous liquid form produced by the non-destructive refining of crude oil during petroleum refining.
The exact chemical composition of bitumen is dependent on the chemical complexity of the original crude oil and the manufacturing process.
Penetration bitumen grade 160/220 has properties of 160~220 desimilimeter and softening point 35~43 Deg.C.
Bitumen 160/220 could also be a specialist fuel grade, typically exclusively created in regarding 65th of refineries around the world and with a yield of exclusively 3%~4% of the total crude slate, bituminous crudes from the likes of oil countries tend to supply rather additional, but these a further specialized refinement methodology, means that on the way facet the potential of most ancient refineires.

Application of bitumen 160/220 grade:

Penetration bitumen grade 160/220 is used for paving, road construction and used for hot mixed asphalt because of the properties of very strong viscosity compared to other grade.
