Silicone Bonded Resin Poor VPI Glass Mica Tape
Ruby Mica® Glass / Mica Silicone VPI Tape is a lamination of calcined muscovite mica paper with glass cloth. High thermal-grade silicone resin is used as a bonding agent making it a Class H insulation product. Mica paper is infused with Aramid* Fibroids to strengthen and enhance its resin-absorption capabilities making it suitable for vacuum pressure impregnation (VPI). Post-curing temperature-index is 200°C.
A choice of uncalcined highly porous muscovite mica paper with Class F epoxy resin as a binding agent is also available. This Glass / Mica Epoxy VPI Tape contains zinc napthenate as an accelerator.
Main slot wall insulation of conductor coils and bars in HT motors and generators. It is suitable for both hand and machine-taping on coils / bars of high-voltage rotating-machines. Its outstanding resin-penetration properties make it ideal for single vacuum pressure impregnation of fully-wound stator coils.
Tapes are packed in airtight robust boxes protecting them from dirt, dust and moisture. The packaging also ensures safe transit and storage.
