Carlisle Celebrates 50th Anniversary of its Proprietary TyrFil Flatproofing Technology USA - English Share this article CARLISLE, Pa., March 16, 2021 /PRNewswire/ -- Carlisle TyrFil (www.CarlisleTyrFil.com) this year celebrates the 50 th Anniversary of its signature TyrFil brand—the world's first polyurethane tire fill material intended to flatproof tires. Over the past five decades, TyrFil has become the industry standard in tire fill flatproofing and is utilized in over 65 countries. The company is proud to be the proven supplier to the world's top equipment manufacturers and has the most OEM tire fill approvals in the industry. Rendering tires virtually "flat free" on the job, TyrFil enables off-the-road (OTR) equipment to literally glide over typical work site debris—such as sharp rocks, nails, glass, and rebar—that would otherwise leave machinery vulnerable to dangerous and costly tire punctures. TyrFil can be pumped into any pneumatic tire to replace all of the air with a resilient, synthetic elastomer core that eliminates flats and offers super shock absorption, ensuring a smoother ride for equipment operators, while vastly reducing tire wear, tear, and denigration. Despite cuts and punctures, filled tires will keep performing – increasing productivity and eliminating costly downtime for field operators.
