40/50 Bitumen

Definition:
It is a kind of bitumen, which is provided during the process of oxidation of vacuum bottom (the bitumen production feedstock that derives from distillation tower residue in vacuum oil refineries) at bitumen production units. In a manner that its penetration point (kind of test to indicate the hardness of bitumen) becomes between 40-50.

85/25 Bitumen

Definition:
at the bitumen production reactor, during the air acting, the mixture of the two Vacuum Bottom (VB) and Vacuum Silabes (VS) feedstock is put under a special degree of pressure and temperature between 200-300C of which the hydrogen atoms content in bitumen molecular oxidize to oxygen of air, and obtains with higher hydrocarbons polymerization reaction that has lower penetration and higher softening points than the primary pure bitumen. This kind of bitumen has the softening point of 85 and permeability of 25.

Definition :
at the bitumen production reactor, during the air acting, the mixture of the two Vacuum Bottom (VB) and Vacuum Silabes (VS) feedstock pressed under a special and temperature pressure between 200-300C of which the hydrogen atoms content in bitumen molecular oxidize to oxygen of air, and obtains with higher hydrocarbons polymerization reaction that has lower penetration and bigger softening points rather than the primary pure bitumen. This kind of bitumen has the softening point of 90 and permeability of 15.
