Mica Tube
Mica Tube
The Rigid Mica tubes made by the high grade muscovite mica paper or phlogopite mica paper with the silicone resin, that has excellent mechanical strength and electrical properties.
It is USED as supporting insulation for electrode bar or bushing line in motors, electric smelt metal oven and so on.
FEATURES:
- High-temperature insulation
- High dielectric strength
- Excellent mechanical strength for durable industrial elements.
- Length:10-1000mm, ID:3-300mm
Welcome your customize size and demand.
