Features of high silica fiberglass fabric

Continuous High Temperature

 The high silicon oxide cloth has a high purity Sio2 content of more than 96%, which has heat resistance characteristics.

The high-silica fabrics submitted by Heaterk to the ASTM organization can be used continuously at 1000℃ under the standard test environment (ASTM-E84), the instantaneous heat resistance temperature can reach 1400℃, and the softening point is close to 1700℃.


Environmental Friendly

The amorphous silica fabric comprises high-strength, high-purity 96% amorphous silica fiber, does not contain asbestos and harmful gas, and adopts high-density plain or twill weaving technology non-irritating to the human body and ensures the safety of your business and personnel.


Easy to Process  

High silica cloth is a heat-resistant and soft particular crystal fiber fabric, which has the characteristics of high strength and easy processing.

Excellent softness makes amorphous silica fabric easy to cut and sew into fireproof clothing, blankets, curtains, etc.


Thermal and Sound Insulation

Silica glass fabrics has the advantages of low thermal conductivity, good chemical stability, good electrical insulation performance, low thermal shrinkage, and good sound insulation performance. It can play a better substitute role in the use scenario of glass fiber failure.


Weather Resistance

High-silica fabrics have the same excellent fiber properties as glass fibers and will not expire.

The performance of the fiber at room temperature will remain the same with time, which is convenient for long-term storage and use.
