Features
Youth Tech have produced SiO2 granules and powder with our own technology and equipment. "SiO2 granules have special properties as coating materials of optical lens and filters. Futhermore." They can be used in roofy tilem telecommunication and electron industry. SiO2 powder is produced by our own process with chemical system and has an ultra high purity with globular shape. It is also a main material in coating the optical sputtering targets.
Characteristics
- SiO2 Granules : Vacuum evaporating materials
- SiO2 Powder : Optical coating materials for sputtering targets (synthetic)
- 99.999% purity
- Anti scratch hard coating
- Anti UV/Fog
- Multilayers
Applications
- SiO2 Granules
EMC filler, anti-reflective coatings for ophthalmic, vacuum evaporating material, sunglasses/UV-protection, decorative coatings, multi-layer stacks, filter (optical instruments), fiber optics, car headlights coatings, anti-reflective coatings (CRT)
- SiO2 Powder
optical coating sputtering target, EMC filters, optical composite catalyst support, CMP slurry.
