Crystal Bitumen
- Packing: Jumbo Bag
- MOQ: 1000 MT
- Payment Term: TT Method
Crystal Bitumen is also the bottom residue of the vacuum distillation tower, and it is stiff and brittle.
The acceptable penetration ranges of Crystal Bitumen, based on ASTM D5, lay between 1 to 30.
The penetration range gets determined by the quality of the crude oil, which the bitumen derived from.
Crystal Bitumen has no elasticity, and according to the Test Method of ASTM D113, it is quite dry, and the Ductility is below 10 cm.
Crystal Bitumen also has a higher flash point than Iraqi bitumen and prime bitumen. Due to the brittleness of the crystal bitumen, the softening point is about three times more than the Prime bitumen, which shows it is not a soft product at all.

Note that the crystal is the residue of the distillation tower, it cannot be inspected.

Price-wise, Crystal bitumen is cheaper than the Prime bitumen.
It has particular applications; and more economically efficient.
Solid and brittle Crystal bitumen packed in one-ton jumbo bags, is mostly used in China to improve the quality of Penetration bitumen.
