Bitumen Oxidized 85/25 Description
In the bitumen production reactor, a mixture of the two starting materials, vacuum soil (VB) and vacuum sinus (VS), is subjected to a special pressure and temperature of 200-300 °C while being exposed to air, to produce hydrogen Atoms, of which the molecules in bitumen are oxidized by atmospheric oxygen, initiate polymerization reactions with higher hydrocarbons.
Oxidized bitumen 85/25 is based on petroleum bitumen made by expanding bitumen 60/70 with very hot air.
Used in industry, this product has predominantly “solid” properties at ambient temperatures, offering better adhesion and water resistance when applied and cooled at higher temperatures than bitumen oxide.
Uses of Bitumen Oxidized 85/25
Bitumen 85/25 has many uses. B. Chemicals, fuels, paints, varnishes, pulp and cardboard boxes, textile processing, road construction, paving and civil engineering. It is also used as a roofing material, construction adhesive, building additive, dust binder and insulation. It is also used in asphalt-based coatings, public building claddings, and artificial turf underlays.
Application of Bitumen Oxidized 85/25
Applications of bitumen 85/25 include pipe coating, paving, paint manufacturing, automotive waterproofing and priming. Bitumen is great at reducing water, dust and noise while protecting the underside of your vehicle.
Depository/handling of oxidized bitumen 85/25
Bitumen Oxide 85/25 should be heated at twice the softening point to obtain flowability and viscosity.
The shelf life of bitumen 85/25 is ten years, even with repeated heating and cooling. See the safety data sheet.
Packaging of Oxidized Bitumen 85/25
Petro Bitumen Company manufactures oxidized 85/25 bitumen in a variety of packages such as kraft bags, fusible plastic bags, drums, bulk blown asphalt 85/25 made from impregnated bitumen blown in a controlled hot air process. is a manufacturer of.
Petro Bitumen Oxidized Bitumen 85/25 is available in any grade and is labelled with two numbers indicating softening point and penetration range.
Bitumen grade 85/25 means a softening point of 85°C and a penetration of 25 decimates. Manufactured according to ASTM standards and meets the following specifications:
