Coefficient of Thermal Expansion & Viscosity

Optical Fiber Vessel Tube

Fiber Optical resized quartz tube features high purity, low hydroxyl, good high-temperature resistance, etc.

Application High Transmittance Ozone Free Quartz Tub

High Transmittance Ozone Free Quartz Tube

It is a kind of doped transparent quartz tube that absorbs part of UV-C and has a high transmittance
(typical transmittance > 88%) at 254nn in the ultraviolet region, which can satisfy lamp special requirements at the ultraviolet region.

Composite Quartz Material

The product is a new composite quartz glass material with lower aluminum and alkali metal content. The middle layer is a high purity white opaque quartz material with excellent thermal insulating properties, and the two sides are semiconductor-grade transparent quartz material, which is more stable for use in high temperature areas, and the composite layer is fusion bonded without cavities.

Low melting point UV filtering quartz tubes for automotive lamps

It is a doped transparent quartz tube that is approximately 150°C cooler than conventional quartz glass materials, and its extreme dimensional tolerance control provides superior processability for high-speed, fast-machining lines, as well as low hydroxyl, UV-C filtering properties.

customizable Standard transparent quartz rod

High chemical purity, high temperature resistance, low coefficient of thermal expansion, tight tolerance dimensions, appearance of gas bubble, air line is very little.

Ultra-high purity quartz tube with customized size

UHP quartz tubes are made of high purity natural quartz sand with a total impurity content of about 10 ppm. The contents of alkali metals and hydroxyl groups are very low. It has stable performance under high temperature and high pressure. Finished lamps have the advantages of small size, high brightness, long life, etc.
