Thermoplastic polyolefin (TPO) is one of the fastest growing commercial roofing systems on the market. Developed in Europe in the 1970s, TPO was introduced to the U.S. market in the late 1980s and has become the dominant installed roof system in the industry; now used on 53% of commercial roofs, according to the American Institute of Architects.

Read MoreNatural rubber is an electrically insulating material, but introduction of conductive fillers like carbon based materials (carbon black, graphite, carbon nanofibers or nanotubes) or metal fillers can increase the conductivity of the resulting composite. These materials are frequently used for electromagnetic/radiofrequency interference (EMI/RFI) shielding, and laboratory and military uses.

Read MoreOperations in the tire pyrolysis sector, as part of the tire recycling industry, are maturing to become not recycling operations, but serious producers of high grade raw materials in the rubber supply chain, on equal footing with virgin materials.
Read MoreIt is known that the oil used as a plasticizing agent in rubber compounds has historically been of petroleum origin. These oils include distillate aromatic extract (DAE), treated distillated aromatic extract (TDAE) and medium extracted solvate (MES). Since 2011, Goodyear has been investigating the utility of soybean oil (SBO) as an alternative to replace petroleum based oils. It was found that the unique structural (figure 1) and physical properties of SBO can be harnessed to provide improvements in compound processing and performance for tire applications. Since this discovery, Goodyear has developed multiple products that make use of SBO through extension in solution styrene-butadiene rubber (SSBR) and as a raw material in tire compounds. The benefits of SBO were harnessed through these avenues to create the Assurance WeatherReady tire in 2017, which is the industry’s first passenger tire to achieve full replacement of petroleum based oil with SBO in the tread.
