Technical Notebooks
Rubber technology has played a substantial role in the progressing technical development across industries and continents for over 180 years, and still today there is no substitute. Nevertheless, the rubber industry is in the maturity stage of the life cycle characterized by intense competition and low profit margins, and raising questions about the long-term sustainability of rubber industry products and jobs.
In the last 20 years, several new ASTM test methods have been developed for effectively measuring the quality of mix in the factory. This study measured the quality of mix using these different procedures with the inclusion of recycled rubber powder in the compounds.
How do titanates and zirconates differ from silanes? Monte has spent 50 years teaching how they provide significantly different alternative coupling mechanisms. And he gives insight on this subject in this latest issue of Rubber News’ Technical Notebook—the second of a two-part series.

Tire conversion technologies can be attributed to three generations. Generation 1 mostly was extracting oil from tires; Generation 2 focuses on recovery of carbon black. And the future Generation 3 recovers and upgrades carbon black.
G3C Technologies Corp. takes a closer looks at the value Generation 3 brings to recycling, bringing a new, upgraded approach to a circular economy within the tire industry.
Proficiency testing has multiple uses and benefits for many industries, such as validating test methods and measurement techniques, generating precision statements, investigating causes of systematic error/bias, and more. As it celebrates its 50th year as a proficiency testing provider, Collaborative Testing Services shares its insight on proficiency testing in the rubber industry.
After more than 80 years of use, tires have evolved into a transportation product of unsurpassed universality. Isn't it about time there was a more efficient way to obtain data on their tread rubber performance?
Methods of measuring statistical test sensitivity were published by John Mandel in 1964 and incorporated into ASTM D6600 in 2000, mainly to provide a means of determining the optimal test conditions for effective rubber process analyzer testing.
Graphene is an allotrope, or one of the several physical forms of carbon, other examples being graphite, fullerenes and diamond. At the atomic level, it is in the form of a sheet with a thickness nominally under 1.0 nanometer and up to 1 micron in diameter. Sheets of such dimensions, when added to other composites, facilitate increases in thermal and electrical conductivity and—in the case of elastomer nanocomposites—improvements in hysteresis, compounding ingredient dispersion, aging resistance and reductions in permeability.
This study is intended to uncover universal relationships between O-ring design parameters and their extrusion-resistance performance.
