Heat Resistance Quartz Fiber Yarn For Weaving

1. Product Introduction

Heat-resistant quartz fiber yarn for woven fabrics is a continuous long fiber made of high-purity silica and natural quartz crystals. Its SiO2 content can reach more than 99.95%. It is currently the flexible inorganic material with the lowest dielectric properties and the highest temperature resistance.

Heat-resistant quartz fiber yarn for woven fabrics can replace alkali-free glass fiber, high silica fiber, basalt fiber, etc., and has unique advantages in ultra-high temperature and aerospace fields.

In addition, the linear expansion coefficient of heat-resistant quartz fiber yarn for weaving is small, and it has the rare characteristic that the elastic modulus increases with increasing temperature.
