Product Brief
Quartz fiber untwisted yarn is a cluster made of several strands of quartz fiber filament which are directly parallel and combined without twisting. It is the most basic variety of quartz fiber products, can be used as a product directly for reinforced plastic products, but also some fabrics (untwisted gauze) and non-woven fabrics (felt) intermediate material.

Product advantage

1, excellent dielectric performance: dielectric constant is only 3.74, dielectric loss is only 0.0002. It is the first 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 ~ 100 ºC for 1 x1080 Ω cm, high resistivity, is a good insulating material.
6, chemical performance stability: long-term in acid, alkaline, high temperature, cold, tensile and other bad conditions, corrosion resistance.
