What is Oxidized Bitumen 85/40? Oxidized Bitumen 85/40, also known as blown bitumen, is a semi-solid petroleum bitumen grade resulting from air-blowing asphalt flux. The flux is normally derived by oxidizing asphalt 60/70 with hot air. 85/40 is grade referring to penetration value and the softening point of the material. Softening point is carried out […]
Description of Oxidized Bitumen 90/10 Oxidized Bitumen 90/10 is a high-quality bitumen product manufactured via controlled air-blowing where hot air passes through grade 60/70 petroleum bitumen. The process is carried out in the absence of chemical catalysts, giving a semi-solid product with high softening point, good heat stability, and low sensitivity to temperature changes. The […]
Product Description Oxidized Bitumen 90/40, or blown asphalt, is a semi-solid industrial bituminous product resulting from air-blowing hot air over penetration bitumen (most typically 60/70 grade). The softening point of the bitumen is increased and its penetration value decreased through this process, so that the material can be utilized in applications requiring high heat resistance, […]
Description of Oxidized Bitumen 95/25 Oxidized Bitumen 95/25 is a semi-solid, air-blown bitumen manufactured by oxidizing penetration grade 60/70 with hot air. It boasts better thermal stability, a higher softening point, and reduced temperature sensitivity compared to conventional penetration or viscosity grade bitumen. This makes it fit for demanding applications in construction, waterproofing, insulation, and […]
What is Oxidized Bitumen 90/15? Oxidized Bitumen 90/15 is a semi-solid, thermoplastic petroleum bitumen product. It is made by blowing hot air into penetration-grade bitumen (usually 60/70), which yields a product of higher viscosity, thermal stability, and high adhesion. The numbers 90/15 represent its softening point (around 90°C) and penetration value (15 dmm), according to […]
What is Oxidized Bitumen 105/15? Oxidized Bitumen 105/15, or Blown Asphalt 105/15, is a semi-solid bitumen material produced by blowing hot bitumen with air. This oxidative process increases the softening point of the product and decreases the penetration value, making it more hard and heat-resistant. With a softening point of approximately 105°C and penetration of […]
Definition of Oxidized Bitumen 75/35 Oxidized Bitumen 75/35 is an oxidized Asphalt produced by oxidizing a selected petroleum asphalts without adding the catalyst. Oxidized Bitumen 75/35 has high softening point, high flash point and it is highly stable during melting. As said before, Bitumen 75/35 is based on petroleum bitumen which is made by Blowing […]
