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.
Bitumen penetration grade 160/220
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.
