Up, up and away: WVU engineer uses microwaves to ‘upcycle’ a super-powered plastic
Polypropylene is a superhero that can do and be anything – or almost anything. It’s a plastic resin that keeps us healthy, transforming into medical sutures, prostheses, and surgical masks. It keeps us safe, contributing to the manufacture of impact-resistant car bumpers and hard hats. It keeps us entertained and energized. It’s a popular material for children’s toys, sports equipment like rackets and moisture-wicking performance apparel. And it keeps us comfortable. It’s in the rugs that cushion our footsteps – even in the insoles that support our aching arches.
