In all aspects, they remain true to their “Designed by Snowboarding” philosophy to make riding more fun—and their newest binding entry, the Rome Black Label highback, is no exception. Incorporating composite materials in snowboard bindings is not a new concept. THE SOLUTION When approached with a thermoplastic composite technology that offered the freedom to add torsional flex without compromising on strength and power, the product innovators at Rome were seriously stoked.

They are also up to 100 times more fatigue-resistant than polymers reinforced with short fibers, offering a high degree of mechanical resistance to high loads. In terms of impact resistance, at equivalent levels of reinforcement and using the same matrix material, an LFT formulation is typically about 70 percent higher than that of a short-fiber formulation, and it also has greater stiffness. Our diverse polymer portfolio and collaborative approach can help tailor solutions that optimize part performance and advance lightweighting goals.
