2025 Top 10 high silica fiber Manufacturers in the world

Introduction to High Silica Fiber

High silica fiber is a type of inorganic fiber with a high content of silica (usually over 96%). It is produced through a special process that involves acid leaching of aluminoborosilicate glass fibers. This fiber exhibits excellent high - temperature resistance, withstanding temperatures up to 1000 - 1200°C without significant shrinkage or loss of strength. It also has good chemical stability, low thermal conductivity, and high flexibility, making it suitable for a wide range of applications. These include thermal insulation in industrial furnaces, fire protection in aerospace and automotive industries, and filtration in high - temperature environments.
