Mykroy/Mycalex

What is Mykroy/Mycalex?

Ceramic materials mold like plastics, have a coefficient of thermal expansion close to many metals, and possess electrical and thermal properties superior to most organic plastics.

These dense, rigid materials are easily machined. They are also impervious to moisture, are arc resistant and can withstand thermal cycling and nuclear radiation. Unlike organic materials, they do not outgas, smoke or burn.

Mykroy/Mycalex materials have continuous operating temperature ranges of -459°F to +1300°F. They are produced in sheet and rod form as well as machined parts to meet specific customer specifications. They are also moldable, like plastic, and can even accept metal inserts during molding.
