A Recycled Content Material Solution for TPV Applications


The environmental and health problems associated with scrap tires and discarded rubber items are well known. Whole tires in landfills "float" to the surface. Tire and scrap thermoset rubber piles catch fire and are ideal breeding grounds for mosquitoes and rats. For these reasons, methods have long been sought to utilize waste thermoset rubber products in such a way that an optimum is obtained between as low as possible cost to produce on the one hand and technical applications of the highest possible quality on the other hand. This presentation describes an airless tire application where a recycled rubber based thermoplastic elastomer, ECO-FLEX RTPV, has replaced virgin SBR thermoset rubber with a balance of performance, processability and value. It will include a discussion on performance properties required vs performance achieved and cost benefits.
