applying:
1. For high-temperature insulation: such as rockets, missiles for insulation, earthquake or other high-temperature insulating materials engineering.
2. Used for reinforced plastic: high-temperature production of synthetic resin and high-strength glass fiber reinforced plastic materials. Widely used in aviation, missiles and rockets, and so on.
3. Special cable: use for the foreskin of the cable, used in high temperature on the special-purpose cable.
4. Acid-base for high-temperature filters
for vacuum tube filled with material: water rafah as a quartz tube filled with silk material, in order to improve the performance of the tube, and extend the life of vacuum tube.
