Heat Resistance Quartz Fiber Yarn For Weaving

1. Product Introduction

High-temperature resistant silica fiber yarn for weaving is made from continuous fibers of high-purity silica (SiO₂ content ≥99.95%), which are twisted together to form a bundle. The single filament diameter is typically 5-15 μm, and it can be wound onto a bobbin with different twist directions and ply numbers. 

It has a long-term temperature resistance of 1050-1200℃, a softening point of 1700℃, and a maximum tensile strength of 6000 MPa. It also possesses a low dielectric constant (3.74), low thermal conductivity (coefficient of thermal expansion 0.54 × 10⁻⁶/K), and good chemical stability.

High-temperature resistant silica fiber yarn for weaving exhibits high temperature resistance, high strength, and good insulation properties. It can be used in various textile processing procedures and is widely applied in optical fiber, aerospace, semiconductor, and other industrial fields.

High-temperature resistant silica fiber yarn is currently the most widely available flexible inorganic material with extremely low dielectric properties and extremely high temperature resistance. 

It can replace alkali-free glass fiber, high-silica fiber, basalt fiber, etc, and can partially replace aramid fiber, carbon fiber, etc, giving it unique advantages in ultra-high temperature and aerospace fields. 

Quartz fiber yarn has a low coefficient of linear expansion and the rare characteristic that its elastic modulus increases with increasing temperature.

 In addition, this high-temperature resistant quartz fiber yarn for weaving has a low coefficient of linear expansion and the rare characteristic that its elastic modulus increases with increasing temperature.
