1mm Thick Wall Opaque Quartz Glass Tube
with as below advantage, and be the best choice for infrared heating element.
1. With Infared radiation, and the transmissivity of infrared is arrived to 70-75%
2. With out surface coating and infectant, is a eccellent chemic products
3. With high heat stablility and high temperature resistant.
4. Can be make by various shaped, and ametabolic long using.
5. Heating temperature selective, as well unchangeable radiation ability in long term.
6. Structure reasonable
7. Make used of convenient
8. Quartz infrared red lights
9. Longer service life to 5000 hours
10. OD in 10mm, 23mm
