Wintality Petroleum specializes in Blown Bitumen, also known as Oxidized Bitumen, which is produced by introducing air into penetration-grade bitumen. This process enhances the material's rubbery properties, resulting in a harder and more durable product. The unique characteristics of Blown Bitumen make it suitable for a variety of industrial applications, particularly where enhanced performance and stability are required.
Characteristics of Blown Bitumen
Blown Bitumen is recognized for its high softening point and excellent resistance to high temperatures, making it an ideal sealant to prevent bleeding in applications exposed to heat. The oxidation process not only increases its hardness but also improves its flexibility and chemical stability. This versatility allows it to be used effectively in various sectors, including construction, automotive, and marine industries.
Common Grades
Wintality Petroleum offers several popular grades of Blown Bitumen, including:
- 95/25
- 85/25
- 90/40
- 115/15
We also have the capability to produce custom grades upon request to meet specific client requirements.
Applications of Blown Bitumen
Blown Bitumen has a wide range of industrial applications due to its unique properties:
- Roofing and Waterproofing: Used extensively in the manufacture of roofing felts and waterproofing membranes, providing effective protection against moisture.
- Piling Industry: Acts as an anti-slip layer compound, enhancing safety and stability in piling applications.
- Automotive Industry: Utilized as undercarriage sealants to protect vehicles from corrosion and environmental damage.
- Joint Filling and Sealants: Employed as a joint filling compound for construction joints and saw cuts, where minimal movement is expected.
- Marine Applications: Used in the production of bituminous marine mastic for oil and gas pipeline joints, ensuring durability and resistance to harsh marine conditions.
- Sound Dampening: Incorporated into sound dampening felts for acoustic insulation in buildings and vehicles.
- Coatings and Paints: Serves as a raw material for producing bituminous coatings and paints, enhancing adhesion and weather resistance.
Advantages of Blown Bitumen
Blown Bitumen offers several key advantages:
- Water Resistance: Completely water-resistant, making it ideal for applications exposed to moisture.
- Flexibility: Highly flexible, allowing it to adapt to structural movements without cracking.
- Durability: Chemically stable and durable, ensuring long-lasting performance in various environments.
- High Softening Point: Its elevated softening temperature prevents deformation under heat, making it suitable for high-temperature applications.
