BITUMEN 40-85

STIFF RUBBER BITUMEN
The ingredients Vacuum Bottom (VB) and Vacuum Silabes (VS) are aerated in bitumen production reactors at a certain pressure and temperature (200-300 °C), promoting reactions between the hydrogen atoms in the bitumen and oxygen from the air to produce heavier hydrocarbons—with a lower penetration grade and a higher softening point than the original untreated bitumen—through polymerization. Such bitumen features a softening point of 85 and a penetration of 25.
Application: Coating the bottom of water channels, covering up the cracks and filling the fissures on concrete structures, other construction applications, producing moisture insulation.
