Polyimide is a thin, lightweight organic polymer film that provides excellent tensile strength, tear resistance and dimensional stability. Polyimide heaters are best suited for medical device applications and clinical diagnostic instrumentation requiring low-mass heaters. Polyimide has the additional attributes of low outgassing for and being resistant to radiation, solvents and many other chemicals.
Watlow’s enhanced precision registration cutting provides tight tolerance to fit customers’ application needs. New product features allows Watlow to custom design a heater to meet power supply needs. Watlow can assist in development of polyimide heaters to meet the exact application requirements through precise temperature distribution. By properly bonding or attaching the heater to a customer’s, Watlow creates subassemblies that reduce installation costs for customers.
Applications include IV heaters, respirators, eye surgery endoscope warmers and sleep apnea. The heater operates in environments as low as -319°F (-195°C).
