Scientists at Loughborough University have developed their own software process to optimize sulfur cure systems for rubber. Using a JavaScript programme, cure test results for the sulfur vulcanization of a natural rubber were processed to develop a highly efficient method for selecting the most efficient sulfur cure system. This method removes the need to mix and test the raw rubber with chemical curatives repeatedly to find a compound with ideal cure properties for industrial applications.

Tyre Stewardship Australia (TSA), the Australian Road Research Board (ARRB), and the Victorian Department of Transport (DoT) have turned 1,600 used tyres into a 1.4 km road in Bentleigh, a suburb in Melbourne, Australia, using various mixes of crumb rubber asphalt. According to TSA, this project aligns with Vic Government’s Recycled First Policy and is another example of how good partnerships are helping turn a tyre waste stream into a resource.

Foams produced by moulding are used for example in packaging for electrical appliances, bicycle and motorcycle helmets, armrests in cars and many other applications. In the production process, foamed plastic beads are sintered using steam in order to form components. The choice of materials is therefore limited to those that can be joined within the temperature and pressure range of classic steam molding processes (between 1-8 bar), for example polystyrene (PS), polypropylene (PP) or thermoplastic polyurethane (TPU).
