Initial evaluations conducted by material scientists from American Process Inc. (API) and Aditya Birla Group’s Birla Carbon have found that combining the companies’ Birla Carbon and Bio Plusnanocellulose products significantly lower the rolling resistance of tyres.
In line with this, API and Birla Carbon have signed a joint development agreement to further explore the technical and business potential of combining carbon black and nanocellulose to improve the performance and sustainability profile of tyres.
Research indicates that up to 20% of a vehicle’s fuel efficiency is impacted by the rolling resistance of tyres. Increased commercialisation of low rolling resistance tread material is a key technology development focus area identified in Birla Carbon’s 2016 Sustainability Report.
Over 70% of the world’s carbon black is consumed by the tyre industry, with carbon black constituting 25% of the tyre weight. Within the tyre industry, there are ever increasing demands to improve rolling resistance, traction and fuel economy while maintaining tyre safety and affordability. In addition, with growing populations, economies, and mobility throughout the world, the industry must ensure that technology developments are sustainable and environmentally friendly.
Charles Herd, PhD, Director of Birla Carbon’s Rubber Black Technology, comments, “Low rolling resistance has been and has become an ever increasing area of investment and technological development for tyre manufacturers in all aspects of tyre technology including design, construction and materials. The synergies between carbon black and nanocellulose offer an exciting opportunity to meet the performance and environmental demands placed on us as a responsible manufacturing entity in a global society.”
According to Theodora Retsina, PhD, CEO of API, nanocellulose offers tremendous performance improvements for a variety of materials applications including rubber, in addition to its exceptional sustainability profile. “With strength equivalent to carbon fiber, nanocellulose can improve the strength, durability, and toughness of composites. It also shows unique synergistic effects with other filler materials like carbon black in improving composite performance,” Retsina added.
Kim Nelson, PhD, API’s VP of Nanocellulose remarks, “This partnership has many synergies including Birla Carbon’s technical expertise, rigorous and disciplined development program, and world-class research facility in Marietta, Georgia. Our ability to offer large-scale quantities of a variety of nanocellulose products with various particle sizes and surface chemistries also enhances the development process.”
