Mica Heaters

Mica heaters are manufactured with etch foil heating elements and bonded between two high-temperature mica sheath layers of material. This heater construction provides excellent heat transfer with a quick heat ramp up rate.  Clamped mica heaters must be secured between rigid plates or heated surfaces to prevent layer separation.

Electric Mica heaters provide a conductive heating solution, where there is demand for high temperature and even heat distribution in a low profile lightweight configuration. The heater technology is designed around efficient direct contact conductive heating with element coverages exceeding 50% while most high temperature options are less than 25%. This is achievable by spreading the heat across the most complex configurations.

Custom Mica Heaters for OEMS

Durex Industries engineers, designs and manufactures electric mica heating elements in custom shapes and sizes, to include cutouts and factory formed curves for many OEM markets. Our unique approach is a collaborative process, based on extensive experience with complex OEM product rollouts, assuring that both business and technical requirements are optimized in the design. Durex Industries provides an “engineered solution” to meet your most important heating requirements.
