OD10-OD50mm milky white quartz glass tube customize opaque silica quartz tubing for heating elements

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.
