What is Oxidized Bitumen? Oxidized bitumen, also known as blown bitumen, is produced by passing air through penetration grades, giving it more rubbery properties than its original formula. This hard bitumen is widely used in various industries, including the piling industry, roofing felts, waterproofing, sound dampening felts, and under carriage sealant in the automotive […]
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 […]
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, […]
