TORZEN Marathon™ PA66 resin is an improved, patent-pending product that is made to withstand higher temperatures for longer periods of time. Advantages include ease of processability (due to low melt viscosity) and the possibility to be used in contact with cooling liquids (due to hydrolysis resistance). It’s the ideal solution for engines or other parts that are consistently exposed to intense heat. INVISTA’s TORZEN Marathon™ technology also provides property enhancements for its flame retardant grades. Enhancements include improved mechanical properties retention after heat aging and lower melt viscosity compared with conventional PA66 grades, while maintaining high levels of flame retardant performance. TORZEN Marathon™ branded PA66 resin—with characteristics such as heat-aging performance, low melt viscosity and good hydrolysis resistance — gives molders the opportunity, and potential, to design advantaged parts with as-needed collaboration from INVISTA.Air Zoom Pegasus 34 Leather
