Product Brief
Quartz fiber is a kind of white, soft, shiny inorganic fiber filament, the main component is silica, the general quartz fiber content in more than 99.90%. Quartz fiber is made of high purity silica crystal or natural quartz crystal after high temperature melting and drawn into a monofilament with a diameter of 1-15μm.

Product advantage

1, excellent dielectric performance: dielectric constant is only 3.74, dielectric loss is only 0.0002, is the best wave through material.
2, ultra-high temperature resistance: long-term use temperature 1050~1200ºC, softening point temperature 1700ºC, thermal shock resistance, longer service life.
3, low thermal conductivity: the coefficient of thermal expansion is small, only 0.54x10-6 /K, is 1/10 of ordinary glass fiber, both heat resistance and heat insulation.
4, high strength: no microcrack on the surface, tensile strength up to 6000Mpa, is 5 times of high silicon oxygen fiber, 76.47% higher than E glass fiber.
5, insulation performance is good: resistivity under 20 ºC ~ 1000 ºC for 1 x1018 Ω · cm ~ 1 x106 Ω cm, rate high electric group, is a good insulating material.
6, chemical performance stability: long-term quartz acid, alkaline, high temperature, cold, tensile and other bad conditions, corrosion resistance.
