Isola Military & Areospace

Isola offers high reliability and superior performance laminate materials for extreme conditions.

Isola’s high-speed digital and RF/microwave materials are ideal for military and aerospace applications as they offer high glass-transition temperatures, very high decomposition temperatures and low expansion rates—all attributes required for demanding military and aerospace applications.

Our materials are in stock and ready to ship both domestically and abroad.



Typical Applications

Many of our materials meet the stringent requirements of the Airbus Directive ABD0031, “Fireworthiness Requirements Pressurized Section of Fuselage”, having passed flammability, heat, smoke and degassing of toxic vapors testing.
