7coils milky white spiral quartz tube customize opaque quartz helix coil tube for heating elements

Milky white spiral quartz tube opaque quartz helix coil tube for heating elements

The standard size we have is :5.75 coils, 5.5 coils, 6coils, 6.75coils, 7coils and 8coils

High Softening Point: Withstands continuous operating temperatures up to 1100??C, and short-term exposure up to 1300??C, making it suitable for high-heat infrared heating systems.

Low Thermal Expansion: granting excellent thermal shock resistance (can withstand rapid temperature changes without cracking).

Chemical Purity: Made from high-purity silica (typically SiO2 > 99.95%), ensuring not contamination of the heated environment.

Energy Saving: By diffusing light more effectively and reflecting IR back onto the heat source (in heating applications), it reduces energy consumption compared to clear tubes or metal reflectors.

High Transmittance in Matrix: While appearing opaque, the quartz matrix allows controlled light transmission, ensuring that the light is scattered and transmitted, not trapped inside the material.

Consistent Spectral Performance: Maintains stable optical properties over long-term use, even under intense UV radiation or high temperatures, unlike polymer-based diffusers which yellow over time.
