Low price high quality 4mm quartz tube
Quartz glass type:
1.Fused quartz high quality 4mm quartz tube available as continuous machine drawn and automatic controlled tubing.
2.This glass had the typical characteriastics of high purity, good spectral transmission, well controlled dimension and lower OH and so on.
3.It serves as the first choice of heat resistant material for halogen lamps, mercury lamps, metal halide lamps and other quartz lamps, used in light, chemical, semiconductor and etc
4.This glass can be supplied in the range of 3-450mm outside diameter, 0.6-20.0mm wall thickness and 10-4500mm length.
5.Exhaust tubes with good CPK are suitable for high-speed streamline production.
6.And further processing of trim cutting, fire polishing, bending and pinching and etc. can be done according to the requirement of customers.
7.OH-content can be controled within 20ppm15ppm10ppm5ppm2ppm according to the requirement of customers.
Typical Application:
1.halogen,germicidal with ozone lamps,heater etc.
2.mercury,halogen,heater.
3.metal halide lamps and other applications requiring hydroxyl free material.
4.high rate of transmittance and hydroxyl free(import material produced).
5.high rate of transmittance of high ozone germicidal lamps(import material produced).
6.uv blocking applications including halogen and discharge lamps etc.
7.ozone free uv germicidal lamps etc.
8.optical, sunlight,semiconductor and etc.
