Product Description

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 200-300˚C 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.
