Mica Tapes for Circuit Integrity

Mica withstands temperatures above 700°C without losing its dielectric capability. It is the material that allows cables to keep circuit integrity during a fire per IEC 60331 and IEEE 383. We supply muscovite mica (standard, maximum dielectric strength) and phlogopite (higher thermal resistance and flexibility).

Muscovite Mica FR80M28

Test temp. 750–950°C Strength ≥1.3 kV/layer Best cost/performance

Maximum dielectric strength for tests up to 950°C. Standard grade IEC 60331. Halogen-free.

Phlogopite Mica (FR-P series)

Test temp. up to 1000°C Greater mechanical flexibility Long exposure

Higher thermal resistance up to 1000°C and mechanical flexibility. For long exposure. Halogen-free.

Alternative alloys available: 1050, 1145, 1200.

Instrumentation and control systems — neutron detectors, temperature sensors, reactor protection system — operate with low-level signals extremely sensitive to interference. Copper/polyester for maximum EMI effectiveness, aluminium/polyester as the standard solution.

Copper/Polyester (CU/PET)

Maximum EMI effectiveness for critical nuclear-instrumentation signals. Cu >99.5%.
