Application
Outer tube for automotive lamps and other UV-resistant quartz materials.

Product Feature
Cerium-doped quartz glass absorbs all UV-B and C, and its softening point is about 50℃ lower than that of conventional transparent quartz glass. Low OH, extreme appearance, and dimensional tolerances can meet quartz materials that used in high-end UV protection;
Product Type
