Introduction:
Quartz fiber untwisted yarn
Quartz fiber untwisted yarn is a yarn formed by infiltrating continuous quartz fibers without twisting and plying. Untwisted yarn has better wettability and can be directly used to make various composite materials, and can also be used as the base material of cotton felt or needled felt

SJ113-40	40
SJ113-100	100
SJ113-400	400
SJ113-800	800
SJ113-1600	1600

Quartz Fiber Sewing Thread
It is made of high-twist quartz fiber yarn coated with a high-temperature-resistant lubricating layer. The surface of the sewing thread is smooth, flexible, and has good folding resistance. It can be directly used on industrial sewing machines and can fully replace glass fiber sewing thread, high silica sewing thread, etc. Ideal suture material for 3D preforms

Application:
1) Ablative materials for aerospace (ablative materials for rocket nozzles, ablative materials for space re-entry vehicles, ablative materials for launch pads)
2) Various thermal insulation materials for high temperature environments (aircraft engine environment, fuselage fire barrier, thermal protection of space launch vehicles, thermal insulation of rocket thrusters, etc.)
3) Structural materials for stealth technology (aircraft, missiles, drones, fighter jets, bombers, ships, submarines, etc.)
4) As a wave-transparent composite material (aircraft nose, missile radome)
5) As reinforcement (satellite, warship and radar radome reinforcement)
6) As an advanced thermal insulation material, instead of ceramic fiber, glass fiber, high silica fiber
