Bitumen 10/20- Penetration Grade 10/20
Royal Bitumen Penetration 10/20 is a pure petroleum product. We make it from vacuum bottom by using hot air. It has a penetration of 10 to 20 desi-millimeter.
Also, its softening point is between 65 and 75C. This product is thermoplastic. This means it becomes softer when you heat it and gets hard when it cools down, just like synthetic resin.
