Sustainable materials company Lehigh Technologies Inc. has strengthened its research and development capabilities by investing in new mixing and analytical equipment for its Application and Development Center (ADC) and through the appointment of Chad Jasiunas as technical manager for functional materials. This expansion enables Lehigh to further promote the adoption of its sustainable micronised rubber powder (MRP) material in green tyre applications.
Sustainable materials company Lehigh Technologies has announced two new Board members. Former executive vice president and chief operating officer at Yokohama North America, Jim MacMaster has joined the company’s Board of Directors, while Adel Halasa, PhD, a polymer scientist formerly with Goodyear, has joined its Advisory Board.
US-based green materials company Lehigh Technologies has introduced two new butyl based micronised rubber powders. These products, MicroDyne and PolyDyne, are aimed at tyre and rubber industry customers wishing to reduce butyl rubber expenses while increasing their products’ sustainability.
Engineered rubber powder manufacturer Lehigh Technologies, Inc., has announced the results of studies that show its flagship product, PolyDyne rubber powder, can be used as a chemically functioning element in the manufacture of new tyres. This takes the use of rubber powder in tyres beyond its existing role as a mere static filler and enables the product to add value to the finished tyre.
The research was carried out by the Department of Chemistry at South Carolina’s Clemson University. “There has been some question in terms of the extended use of ultra-fine rubber powder and its realistic functionality in new products,” said Dennis W. Smith, Professor of Chemistry at Clemson University. “Our study illustrates that used tyre rubber powder prepared by the Lehigh process is in fact unique and does offer a value-added reactivity and functionalisation. Breakthrough results from electron paramagnetic resonance spectroscopy (EPR) measurements indicate that the Lehigh process provides a significant increase in free radicals, which can bond to matrix resins or other application-specific substrates, extending the powder’s usefulness beyond that of an added filler. With this study, tyre manufacturers worldwide have a viable alternative ingredient that can be used to make ‘green’ tyres, while at the same time enhancing the performance of the tyre. We’re confident that tire manufacturers will see the environmental and economical benefits that PolyDyne powder brings to the table.”
