   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. Specialcable: use for the foreskinof the cable, used in high temperature on thespecial-purpose cable. 

4. Acid-base for high-temperature filters 

5. 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,andextend the life of vacuum tube
