High Silica Yarn

The high silica yarn is made of fiberglass yarn by acid-leach. The content of SiO2 is greater than 96%. 

The high silica yarn has properties of non-asbestos, high temperature resistance, corrosion resistance, aging resistance, high strength and high modulus. 

The 440tex high silica yarn can be coated with 10% PTFE rubber, which is used for thermal electrical apparatus, like hair drier. 

The 10% PTFE coating high silica yarn can stand 360℃. 

The high silica yarn is suitable for electric insulation as the specially wrapping yarn.

Wording temperature: 1250℃

Filament diameter: 5~9um.

Linear density: 120 Tex (60Tex * 2)，220 Tex (73Tex * 3), 440 Tex (73Tex * 6) or 540 Tex (180Tex * 3)
