Hiwa Oil Co, bitumen penetration grade 200/300 is used mainly as a paving grade, which is suitable for road construction, and maintenance, and also water proof projects. Bitumen 200/300 is one of the other most used bitumen and a based product.
Penetration bitumen grade 200/300 is produce by process of vacuum Bottom (VB) and air in the reactor. And due to the control of the process conditions, we reaching to pure quality of penetration grade bitumen 200/300 which has a penetration 200 to 300. The penetration grade bitumen 200/300 has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures.
Guaranty and safety of penetration grade bitumen 200/300
Hiwa Oil Co, guaranty the quality of penetration grade bitumen 200/300, while inspecting by international inspection companies, the both quality and quantity of Penetration Bitumen grade 200/300, at loading port before loading and completing containers stuffing. The penetration Bitumen grade 200/300 also has its own prove of product quality of each batches by QC, while producing in refinery and before shipping. Hiwa Oil Co, guarantees the quality which meet with ASTM, according to following specification.
