Non-pneumatic tires (NPTs) use a precise geometric web rather than air to carry load and absorb shock, which removes the risk of punctures, blowouts and daily pressure checks. Performance depends on the polymer: standard rubber generates too much heat and adds weight under high-speed flexing. The white paper makes the case for Arnitel — a thermoplastic copolyester (TPC, also referred to as TPEE) — over TPU across the properties that matter in the repeated compression-and-recovery cycle: flex-fatigue endurance, high load-bearing capability and dynamic creep resistance, which prevents permanent flat spots after standing under load. It also covers a roughly -30 to +100 C operating window, good low-temperature ductility, and resistance to hydrolysis, chemicals and microbial attack. As a thermoplastic, Arnitel is re-meltable and recyclable. With a service life cited at two to three times that of pneumatic tires, NPTs reduce downtime and total cost in agriculture, construction, mining, ATV/UTV, golf and lawn-care fleets, and lower lifecycle CO2 — reliability that becomes more important as off-highway vehicles move toward autonomy.
