Carlisle Construction Materials changed the name of its polyurethane tire fill business from Accella Tire Fill Systems to Carlisle TyrFil. Carlisle acquired the unit as part of its purchase of the Accella Performance Materials family of companies in November 2017. The brand, which is a leading global tire flat-proofing solution for the Off-the-Road (OTR) equipment marketplace, has offered the industry a trusted, go-to-source for tire fill (commonly referred to in the industry as foam fill) flat-proofing technology for nearly 50 years.
