Frequently Asked Questions

What is high silica fiber?

High silica fiber is a type of glass fiber containing over 96% silicon dioxide (SiO₂). It offers exceptional thermal stability and is used in high-temperature insulation and fire protection applications.

What are the temperature limits?

Our high silica fibers withstand continuous use up to 1000–1200°C, with short-term exposure to 1600°C (e.g., welding sparks or flash heating).

Can you customize products?

Yes. We offer custom treatments including preshrunk fibers, and coatings with Silicone, PTFE, PU, Acrylic, Vermiculite, Calcium Silicate, Graphite, Graphene, PVA, EVA, and aluminum foil.

What industries use your products?

Our materials are used in aerospace, metallurgy, energy, welding, automotive, and industrial furnace sectors for insulation, fire curtains, blankets, and protective barriers.

Are your products environmentally safe?

Yes. High silica fibers are non-toxic, non-combustible, and do not release harmful fumes when exposed to high heat.
