MACOR can be joined or sealed to itself and to other materials using epoxy – metallised parts can be soldered, and brazing is used to join various metals to MACOR. Sealing glass produces a reliable tight seal which can be used for high vacuum environments. With a high maximum operating temperature (1000°C under no load, 800°C continuous load) and the flexibility of intricate shaping / precision during manufacture; MACOR offers a higher grade solution to your technical industry’s requirements.
Mykroy shares many properties with MACOR, acting as a highly versatile solution to expensive ceramics, being a more cost-effective option for less heat dependant solutions. High Dielectric Strength Low-Loss Factor Heat Resisting Non-Tracking, Low Expansion Co-Efficient ,Strong and Rigid; does not creep or deform unlike ductile materials, Low Thermal Conductivity; high temperature insulator, Electrical Insulator, especially at high temperatures, Excellent with high voltages and a broad spectrum of frequencies, Zero Porosity, Radiation Resistant, No outgas in vacuum environments when baked out.
