Pyre-ML RC-5057 Polyimide IST Polyimide ADHESIVE THE CHOICE FOR HIGH PERFORMANCE WIRE PROTECTION is and has always been Pyre-ML®. Pyre-ML® products are part of a family of materials based on aromatic polyimides, one of the most thermally stable organic materials known to man. These products include Pyre-ML® Wire Enamels, Liquid 'H' Enamel. Insulating Varnish, and Pyre-ML® Thinner. You're never far from a PYRE-ML protected product. From household products like washing machines, power tools and fans, to cars, trains and aircraft, Pyre-ML® protection is at work day in, day out. In applications where failure of a lesser product could create a life-or-death situation, the stability and 'reserve protection' of Pyre-ML® makes it the logical choice. The clear leader. During decades of commercial and military use, Pyre-ML® products have been recognized as having the finest thermal stability, radiation resistance, solvent resistance, cryogenic resistance and electrical properties of any enamel available. This unique combination of properties makes Pyre-ML® especially suitable for tough applications where actual conditions can go 'beyond spec', requiring a superior product with plenty of reserve capabilities. Taking the heat: Superior overload resistance. Pyre-ML's ability to protect against high temperatures is why it is used to protect motors, generators, transformers, and other apparatus which operate continuously at temperatures up to 240 ºC. It also protects heavy-duty motors which, due to temporary extreme overloads, acceleration torques, or stalls, are subjected to even higher temperatures (up to 400 ºC) for limited periods. This thermal stability and very low tendency to give off volatile compounds also makes Pyre-ML® perfect for use in sealed relays designed for use in a vacuum. And the near absolute insolubility of Pyre-ML (especially Freon resistance) has led to its wide acceptance in hermetic refrigeration systems and certain liquid filled transformers. Simple application on a myriad of materials. Pyre-ML® wire enamels can be applied to all sizes of round, square, and rectangular wires by conventional die coating techniques. They have also been applied to irregular surfaces using other techniques such as spraying, drop dispensing, and brushing. Copper, aluminum, brass, nickel, and chrome alloy have all been coated successfully. Pyre-ML® has also been used for coating glass servo wire and special hookup wires insulated with surface-treated Teflon fluorocarbon resin. Pyre-ML® Wire Enamels (RC-5019, RC-5057, RC-5069) Applications: transformers, hermetic motors, traction motors, appliances, power tools, mine motors, submersible, pump motors, gas chromatograph capillaries, semiconductor devices, liquid crystal displays, instrument wires, optic fibers, adhesives.
