General description of bitumen 20/30
Hard bitumen but categorized in penetration type 20/30 is a bitumen using as waterproofing and isolation also specially industrialÂ
Softening point and penetration of bitumen 20/30
Penetration grade bitumen supplied by ATDM is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by ATDM is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration between 20~30 desi-millimeter and softening point between 55 ~ 63C. The penetration grade bitumen 20/30 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade has very strong viscosity compare to other grades.
Guaranty/warranty
ATDM guaranty the quality of bitumen 20/30 with arrangement of international inspector to check quality and quantity of the bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. ATDM guaranty the quality to meet with ASTM/EN 12591.
