Blown Bitumen 105/35 Description:

Blown Bitumen 105/35 is a high-quality grade of oxidized asphalt primarily used as a bonding compound and hot melt adhesive. It is applied at a rate of approximately 1 kg/m³ to bond preformed sheets together and to various structures. This grade of oxidized bitumen is produced through the air-blowing process using Bitumen 60/70 as the feedstock.

Production Process: Blown Bitumen 105/35 is manufactured as a semi-solid oxidized grade of pure petroleum bitumen by air-blowing through an asphalt flux. This process imparts special physical properties to the bitumen, making it suitable for various applications in the construction industry.

Quality Assurance: BITUPLUS Company ensures the quality of BITUPLUS Blown Bitumen 105/35 by employing international inspectors to verify both quality and quantity during the loading process onto vessels. Additionally, production is monitored by QC through batch test reports before shipping, guaranteeing compliance with ASTM standards.

Applications: Blown Bitumen 105/35 has a wide range of applications, including:

• Chemical industry for the production of fuel, lacquers, varnishes, and more.
• Paper-pulp-board manufacturing and textile processing.
• Road construction and pavement applications.
• Paint manufacturing and crack sealing.
• Civil engineering projects.
• Roofing and construction businesses for sealing and insulating buildings.
• As an adhesive and additive in construction materials.
• Dust-binding and coating applications.
• Insulation and impregnating agent.
• Manufacturing of rubber and plastic products.
• Paving applications.
• Asphalt-based paints for corrosion protection.
• Lining public works structures.
• Adhesives in electrical laminates.
• As a base for synthetic turf.
• Water-proofing applications and corrosion resistance for pipe coatings.
• Use in Portland cement pavement.
• Hydraulic applications.
• Vehicle undercoating in the automobile industry, providing waterproofing, dustproofing, and noise-proofing.

Application Guidelines: To use Blown Bitumen 105/35, surfaces must be dry, clean, and free from loose particles, formwork, curing products, irregularities, slurry, etc. The bitumen should be heated to double the temperature of its softening point to achieve the desired flow and viscosity.

Storage and Handling: Blown Bitumen 105/35 has a shelf life of up to 10 years, provided it undergoes multiple heating and cooling cycles. It is advisable to store Bitumen 105/35 in a sheltered area, protected from rain and direct sunlight.

Packing: BITUPLUS CO offers Blown Bitumen 105/35 in various packaging options, including Kraft bags, meltable plastic bags, drums, and bulk. The product meets ASTM standards and is designated by two numbers indicating the softening point and penetration ranges, with 105/35 indicating a softening point of 105°C and a penetration of 35 desi millimeters.
