Description of Oxidized Bitumen 85/25

oxidized bitumen 85/25 grade have uses in all of the waterproofing and coating industries who have projects in very hot weather because its softening point is about 150 °C. Oxidized bitumen 85/25 produced in bitumen Factory is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air.

This type of Bitumen is hard and breakable. Oxidized Bitumen is the semi-solid oxidized grade of petroleum bitumen categorized in hydrocarbons is normally used for different purposes in the construction industries.

The quality of Oxidized Bitumen 85/25 with the arrangement of the international inspector to check quality and quantity of the during the loading to the vessel and control the production by QC by batch test report before shipping. Our guarantees the quality to meet with ASTM.

Blown Asphalt 85/25 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 85/25

As you know Blown Bitumen 85/25 has solid mode and for using it must turn to the melting mode so must heat it till 230 centigrade for better using for all purpose in due industries.
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 85/25 include roofing, pipe coating, hydraulic applications, 85/25 is mainly using in paint manufacturing and coating in hot area.
The oxidized bitumen should be heated double temperature against the softening point to be able to have flow and viscosity.

Advantages of Bitumen 85/25

  • Durability
  • Flexibility
  • Water Resistant
  • Chemical Stability 

Storage and Handling of Oxidized Bitumen 85/25

Blown asphalt 85/25 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 of Bitumen 85/25

Care should be taken when heating Oxidized Bitumen 85/25 to avoid overheating. also Workers should wear protective masks, gloves, and goggles during application. please make reference to the relevant MSDS.

Packing of Oxidized Bitumen 85/25

Blown Asphalt 85/25 in various packing, including bitumen 85/25 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.
