Hilton Head Island, South Carolina – Alternative sources of natural rubber are no longer in the realm of speculation but are now viable technologies for tire manufacturing, a pair of speakers claimed at the 33rd Clemson University Global Tire Industry Conference in Hilton Head, April 19-21.
REICHSHOF, Germany—Bicycle tire brand Schwalbe is launching a new generation of compounds for its MTB tires in the Evo line, which it claims will improve durability while offering high performance.
In an April 19 statement, the German company said the compound goes by the name of Addix and “solves the typical trade-off between grip, rolling resistance and wear across a much wider range than before.”
To develop the compound, Schwalbe said it used “a state-of-the-art and extremely precise mixing technology which is not generally used in the bicycle tire industry.”
In its statement, the German tire company said the new mixing process “allows for an almost infinite number of parameter variations and, with a new production hardware set up especially for Addix.”
“In terms of durability, our tires have become much more impressive across the board, and the low-temperature properties are now excellent, and not only in the soft compounds,” Markus Hachmeyer, senior product manager at Schwalbe and designer of MTB tires, said.
These robotic muscle-like actuators could replace metal joints in exoskeletons. EPFL roboticists say the silicone rubber elastomer based parts are far more flexible. They could be used to help the infirm move around, while improving posture and reducing discomfort for lower back pain sufferers. SOUNDBITE (English) JAMIE PAIK, THE DIRECTOR OF EPFL’S RECONFIGURABLE ROBOTICS LAB (RRL), SAYING: “We can foresee a new type of technology being brought closer to our daily lives. When I say that, it’s not us trying to bring in Terminator for everyone’s home, but to bring in different types of technology that enable us to live healthier and live with more comfort, and that was not able to be done beforehand.” The robots are controlled by changing the air pressure in special soft balloons that serve as its body. A modular system, they can be moved around the body to where physical support is needed. The team has devised this belt for potential use on stroke patients. SOUNDBITE (English) MATTHEW ROBERTSON, EPFL RESEARCHER, SPEAKING ABOUT THE BELT, SAYING: “In stroke patients I know they have a common asymmetry where they lean to one side and it could be used to correct for that asymmetry and then focus on if you’re using it to restore gait the belt could do the task of providing the support for your upper body.” The belt’s hooked up to a system of external pumps. The team hopes to miniaturise these and place them directly on the belt.
Tokyo – Sumitomo Rubber Industries (SRI) has developed a winter tire using Kuraray-supplied liquid farnesene rubber (LFR) as a performance enhancing additive, the Japanese synthetic rubber supplier announced 20 Feb.
Tokyo-based SRI has used the additive in the production of its latest studless tire Winter Maxx 02, according to Kuraray’s announcement.
LFR is a liquid rubber developed by Kuraray using farnesene, a new biologically derived diene monomer developed by US biotech company Amyris.
A team of researchers, led by the University of Minnesota, has invented a new technology to produce automobile tires from trees and grasses in a process that could shift the tire production industry toward using renewable resources found right in our backyards.
The technology has been patented by the University of Minnesota and is available for licensing through the University of Minnesota Office of Technology Commercialization.
The new study is published by the American Chemical Society’s ACS Catalysis, a leading journal in the chemical and catalysis sciences. Authors of the study, include researchers from the University of Minnesota, University of Massachusetts Amherst, and the Center for Sustainable Polymers, a National Science Foundation-funded center at the University of Minnesota.
“Our team created a new chemical process to make isoprene, the key molecule in car tires, from natural products like trees, grasses, or corn,” said Paul Dauenhauer, a University of Minnesota associate professor of chemical engineering and materials science and lead researcher of the study. “This research could have a major impact on the multi-billion dollar automobile tires industry.”
OLYMPIA, Wash. (Feb. 10, 2017)— A newly issued analysis from the Washington State Department of Health (WSDOH) concluded there is no evidence that cancer rates among young athletes are increased by playing on crumb rubber athletic turf.
“We did not find the number of cancers among soccer players, select and premier players or goalkeepers reported to the project team to be higher than expected based on Washington cancer rates for people of the same ages,” said the executive summary of the analysis from the WSDOH.
A coalition of three synthetic turf associations — the Recycled Rubber Council (RRC), the Safe Fields Alliance and the Synthetic Turf Council — said they were pleased but not surprised by the results of the WSDOH analysis.
Sustainable innovation, and next-generation information and communication technologies were championed at this year’s Tire Technology International Awards for Innovation and Excellence.
