Milky White Quartz Tube

Milky white quartz tubes are made from high-purity opaque fused silica with excellent thermal insulation, low thermal expansion, and strong chemical resistance. The frosted, non-transparent structure provides uniform heat distribution and enhanced durability under high-temperature conditions.
We supply fully customized dimensions, including OD, ID, length, wall thickness, and precision machining such as cutting, polishing, and CNC processing. These tubes are widely used in heating equipment, infrared lamps, laboratory furnaces, and other thermal applications.

Frequently asked questions

It is commonly used in heating elements, infrared lamps, thermal insulation systems, and laboratory equipment requiring stable high-temperature performance.

The opaque structure is produced through controlled micro-bubble distribution within high-purity fused silica. This enhances thermal insulation, reduces light transmission, and improves heat uniformity.

They typically withstand continuous temperatures up to 1050°C, with short-term peak endurance around 1200°C. Performance may vary depending on heating method and installation conditions.

We can customize outer diameter, inner diameter, wall thickness, and length based on your drawings or specifications. Special tolerances and machining are available.

We offer cutting, grinding, fire polishing, beveling, drilling, slotting, threading, and CNC machining for complex shapes or tight tolerances. Processing is performed according to your drawings.

Yes. For custom sizes and machining, small-batch or prototype orders are possible. The exact MOQ depends on the specifications, tolerances, and required processing steps.
