LEVERKUSEN, Germany—Air Fom wants to make sure your next bike ride doesn't fall flat.
The Taiwanese tire manufacturer has developed a solution for deflated tires, using thermoplastic polyurethane (eTPU) from Covestro A.G. to produce airless bicycle tires.
Air Fom uses particle foam casting to manufacture a multi-layer foam insert. Expanded TPU is molded into the specified shape "and exhibits precisely the desired properties on the rim," the company said in a July 2 statement.
"The tire insert is just as lightweight and elastic as an air-filled tire," the company said. "It can be fitted quickly and firmly on standard rims, is maintenance-free and, most importantly, recyclable—unlike the butyl rubber tubes that are used in conventional tires."
