Superior Performance Characteristics
SUNDEAR quartz glass tubes are engineered to excel in the most extreme environments, offering four critical performance advantages:
Exceptional Optical Transmittance
Our high-purity quartz tubes offer superior light transmission from the ultraviolet (UV) through the infrared (IR) spectrum.
This makes them the ideal choice for UV lamp quartz sleeves and optical research applications.
Extreme High-Temperature Resistance
Built to endure the heat, our tubes maintain structural integrity at continuous working temperatures of up to 1100℃, with short-term peak resistance up to 1300℃.
Perfect for furnace quartz tubes and semiconductor processing.
Unmatched Heat & Thermal Shock Resistance
With a near-zero coefficient of thermal expansion, SUNDEAR quartz glass exhibits incredible heat resistance.
It can withstand rapid, drastic temperature fluctuations (thermal shock) without cracking or shattering, ensuring safety in volatile industrial processes.
Strong Acid & Alkali Resistance
Quartz is chemically inert to most media. Our tubes provide strong acid and alkali resistance (with the exception of hydrofluoric and hot phosphoric acids), making them the gold standard for laboratory quartz glassware and chemical reactor linings.
