Use:
~ LCD manufacturing equipment
~ Single fiber light-emitting whole body single-ended tube
~ Heat exchangers, steam piping
~ High-purity reagents Pipeline
~ A variety of corrosive media (harsh solvents) pipeline
~ Submersible motor with a slot insulation tube
~ Air-conditioning control wiring harness assembly
~ All-inclusive fluoride O-ring plastic tube
Features:
1. High and low temperature resistance
-200 ~ 200℃ high temperature
2. Not sticky, water fight, fight oil
3. Electricity reliability, high insulation
Under 60HZ60MHZ, dielectric constant is 2.1. Even if firing, and it will
stll insulate.
Volume resistance > 10^18Ωm
Surface resistance > 2 X 10^13Ω
Voltaic Arc > 165 seconds, insulation
4. Corrosion resistance
Only under high temperature, fluorine and alkali metals will have
chemical reaction, no reaction with all of other thick and thin
inorganic acid, alkali, ester.
5. Low water absorption
Low suction rate < 0.01%
6. Incombustibility
The air will not burn. (Oxygen index > 95vol.%)
7. Weather resistance
Under ozone and sunshine for long time
8. Easy to process for second time
Can be self-close, self-welding, flanging, it can make into coil pipe
