Oxidized Bitumen 85/35

Description of Oxidized Bitumen 85/35

Oxidized Bitumen 85/35 is semi solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. In fact, Oxidized asphalt 85/35 is based on petroleum bitumen which is made by blowing grade 60/70 bitumen by hot air. Oxidized Asphalt 85/35 is produced by either Continuous or Staggered Blowing Process. Heated Penetration Grade Bitumen under controlled environment is blown with air which controls the Oil Content in the Bitumen while it oxidized.

Oxidized Asphalt 85/35 is the semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction business. The softening point value is the degrees Centigrade measured by the Ring and Ball method as determined by ASTM D36.

The penetration value is in 1/10 mm as determined by IP49 or ASTM -D5. Oxidized bitumen has a higher softening point than viscosity grade and penetration bitumen. Consequently, oxidized bitumen is less susceptible than penetration bitumen and viscosity bitumen to temperature changes.

Uses of Oxidized Bitumen 85/35

his kind of bitumen is suitable to be used in the chemical, raw material for bitumen coat, paper-pulp-board, textile processing, pavement, crack seal and repairmen, civil works, bitumen coat for piping, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding, insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products.
typical uses for bitumen 85/35 include roofing, pipe coating, hydraulic applications, 85/35 is mainly using in paint manufacturing and coating in hot area.

Storage and Handling 

Blown asphalt 85/35 is best up to 10 years from the day it was manufactured. It is suggested for higher time of warehouse keeping to keep the bitumen under shelter and out of the rain and sun shine.

Health & Safety 

Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline.

Advantages of  blown asphalt 85/35

• Durability
• Flexibility
• Water Resistant
• Chemical Stability 

Packing of Oxidized Bitumen 85/35

Blown Asphalt 85/35 in various packing, including bitumen 85/35 is available in 20 & 50 Kg Kraft Paper Bags 25 Kg Carton box & 150, 180, 200 Kg Steel Drums:

25kg carton box

25kg mold packing

It is most expensive packing since there is mold on and with same mold we can ship out. The mold is carton and at destination you can remove the mold easily.

25Kg Polyamide bag

It is heat resistance bag and filling directly in water to cool down fast. It is firstly use not possible to take out the Polyamide from the bitumen and then use.

25kg craft bag

Craft bag is recycle packing and inside is special material to prevent sticking the bitumen to bag. This grade also possible to load on pallet or without pallet for customer.
