Features:
- High dielectric properties.
- Extreme wear and abrasion resistance.
- Chemical corrosion resistance under high temperature.
- Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800C.
- Gas tight for many applications to provide protective atmospheres or high vacuum at high temperature to eliminate contamination or impurity.
