ISO-foil R is used as slip plane in coreless induction furnaces to prevent early leakage and costly damage to the coil. Its high mica content provides a good heat transfer with an efficient dielectric strength. Moreover, the smooth surface of this mica foil material makes the push-out easier by avoiding damage to the crucible. Actually, ISO-foil R replaces the Sinter Product line advantageously.
ISO-foil R is made of phlogopite mica paper impregnated with a specific high temperature binder and reinforced with a glasscloth in the middle. Such design offers a better tensile strength during handling and application. This mica foil is 100% free of toxicity: you don’t need any specific protection.
