Our Technical Ceramics offer high-temperature material solutions for extreme environments. Contact us to find out more about Ceramics and Graphite ranges.
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.
