Product Description

Product Brief
Quartz fiber is a kind of white, soft, shiny inorganic fiber filament, the main component is silica, the general quartz fiber content in more than 99.90%. Quartz fiber is made of high purity silica crystal or natural quartz crystal after high temperature melting and drawn into a monofilament with a diameter of 1-15μm.

Product advantage
Quartz fiber maintains part of the properties and characteristics of quartz crystal and is an excellent high temperature resistant fiber material. Quartz fibers have a very high silica content and can be used for a long time at 1050 ° C. In addition, it also has a series of characteristics such as high strength, small dielectric constant and dielectric loss, small coefficient of expansion, corrosion resistance, good design performance and so on. It is an indispensable strategic material in the field of aerospace.
