Overview
Wound micanite tubes — mica paper and binder rolled and cured into rigid insulating cylinders for heating elements, terminals and bushings. Phlogopite silicone-bonded tubes hold dielectric integrity at heater temperatures where polymer tubing fails; part of the micanite components lane where Germany, the UK, USA and Japan are priority buyers.
Supplied by Wedge Industries Limited with manufacturing and processing bases in India, UK, Spain and China, exporting to 45+ countries.
