What is Oxidized Bitumen?
Blown bitumen grades or Oxidized Bitumen are produced by passing air through the penetration grades. This process gives the bitumen more rubbery properties than its original formula and they are simply harder bitumen. Hard bitumen under controlled temperature conditions is widely used as an anti-slip layer compound in the piling industry, for manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts and under carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound and many others. Also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for the oil & gas pipeline joints.
The most popular grades are; grades 95/25, 85/25, 90/40, and 115/15. We are also capable of producing other grades of Blown Bitumen upon request by our customers. Oxidized Bitumen high softening temperatures qualify them as excellent sealant for prevention from bleeding in high temperature applications. Blown Grade Bitumen shall be broken up into small pieces (for blown grade in molded cake form) and heated slowly to the application temperature of 220ºC to 230ºC. Oxidized Bitumen is predominantly used in the piling industry as an anti slip compound for the manufacture of under carriage sealants in the automobile industry. It is also used as a sealant compound, as a joint filling compound apart from being used in the manufacture of roofing felts and sound dampening felts. Further, Oxidized Bitumen is used in the manufacture of bituminous marine mastic, which is required for the oil and gas pipeline joints. This Oxidized Bitumen is available in different grades like 95/25, 85/25, 75/25, 90/40 and 115/15. Oxigil is also capable of producing other grades of Oxidized Bitumen according to the specifications of individual clients.
Some of the major advantages of Oxidized Bitumen are that it is completely water resistant, highly flexible and durable. Further, it is chemically very stable. Oxidized bitumen is a very flexible compound that is not only chemically stable but also a very durable compound apart from being completely water resistant. Lastly, Oxidized Bitumen has some very prominent technical advantages that makes it a very sought after compound in various applications.
Oxigil certifies every single batch sold, taking samples and analyzing them in our laboratories.
We provide to our customers SGS certificate inspections of quality and quantity, if required.
Quantity Inspection: SGS cargo visual inspection is requested to ensure that the cargo is loaded in good condition and stowed properly. The GSS report mentions container numbers, quantity of pallets or bags, pictures of cnt during loading operations.
Quality Inspection: SGS certification service enable us to demonstrate that products, processes, systems and services are compliant with national and international regulations and standards. This service enable us to operate in a more sustainable manner by improving quality and productivity, reducing risk, verifying compliance and increasing speed to market. SGS Controller certifies our Oxidized Bitumen making a visual inspection during Penetration test and Softening Point Test made by our QC Chemists.
Penetration Test: done according to Standard UNI EN 1426:2002 and using Penetrometer test machine.
Softening Point Test: done according to Standard ASTM D36-95 and using Ring and Ball Apparatus machine.
