Expanded Recycled-Content Portfolio of TPEs
Avient has expanded its reSound R recycled-content TPE through collaboration with sustainable PVB provider Shark Solutions.
The latest addition to the reSound R recycled-content TPE portfolio from Avient are new TPEs that contain 25% PCR content from PVB (polyvinyl butyral) reclaimed from broken automotive windshields and laminated architectural glass. These materials are a result of close collaboration with Denmark’s Shark Solutions (recycling facilities in Atlanta, Ga., and Victorville, Calif.). a global leader in advanced PVB products. Available globally, the new reSound R TPEs are formulated with regionally recycled PVB.
Developed in 45 to 55 Shore A durometers, the new reSound R grades are said to be ideal for general-purpose applications in the consumer and automotive industries. Both injection moldable TPEs can be overmolded to PP and come in a natural grade that can be easily colored. These reSound R grades with PCR content reportedly offer similar performance properties to traditional TPEs and are suitable for many durable consumer products and grips – such as personal care items, lawn and garden tools, golf clubs, and footwear. Their performance properties also fit automotive applications that could benefit from vibration damping, such as door mats, door damping and glove boxes.
It is estimated that 75 million broken windshields need replacing each year. This abundant supply includes thousands of tons of PVB, found in the inner layer of the glass, potentially bound for landfills. Instead, the outer glass is recycled and the PVB is reclaimed and reprocessed for various uses, including an alternative raw material source for polymers. Avient’s unique formulation expertise allows the supply of reprocessed, high-quality, non-toxic PVB to be upcycled into more sustainable TPEs with excellent properties.
Said Matt Mitchell, global marketing director for Avient’s Specialty Engineered Materials, “This technology brings together advanced material science and innovation to support customers' goals and the circular economy. These material developments create an opportunity to help divert mountains of valuable resources from the waste stream and upcycle them into new products that offer excellent performance and value.”
