1.Characteristics of high silica fiberglass yarn

High-silica fiberglass yarn is an inorganic fiber high-temperature resistant inorganic fiber yarn made of Na₂O-B₂O₃-SiO₂ ternary system glass balls through drawing, annealing and post-treatment, and the content of silicon dioxide (SiO₂) is usually above 96%. After special acid treatment and heat treatment, it has excellent thermal stability, thermal shock resistance, and insulation, and is suitable for extreme high temperature environments.

High silicon content ≥96%: stable structure, not easy to melt;

High temperature resistance up to 1000℃, instantaneous temperature resistance up to 1450℃;

Low thermal shrinkage: no deformation or brittleness at high temperature;

Good electrical insulation and low dielectric constant;

Strong corrosion resistance, oxidation resistance, and radiation resistance.

2. Advantages of high silica fiberglass yarn

Continuous high temperature resistance and strong thermal stability

Good chemical stability, adaptable to harsh environments

Green and environmentally friendly, no asbestos, no toxic gas release

Dimensionally stable, not easy to break or retract

3. Typical application scenarios

Fireproof cable sheathing materials

High-temperature sutures, insulating sewing threads

High-temperature webbing, fireproof cloth, thermal insulation blanket weaving

Rocket, aerospace thermal protection cover

High-temperature protective equipment for metallurgy and welding industry

4. Selection and use guide

Main parameter reference:

SiO₂ content: ≥96%

Linear density: 120, 160, 220tex, etc.

Usage suggestions:

Avoid sharp bending during use and try to keep the tension uniform;

The storage environment should be dry and ventilated to avoid moisture absorption;

5. FAQ

Q1: What is the difference between high silica yarn and ordinary glass yarn?

A: High silica yarn has extremely high temperature resistance (≥1000℃), while ordinary glass fiber yarn has a temperature resistance of only 500~600℃. High silica is suitable for extreme working conditions.

Q2: Can it replace asbestos fiber?

A: Yes. It is an environmentally friendly alternative to asbestos, with similar or better thermal insulation and fireproof properties, and is non-toxic and harmless.

Q3: Is it suitable for industrial sewing?

A: Yes. High silica yarn has excellent softness and strength, and is widely used in high-temperature protective sutures, sealing pad sutures, etc.

Q4: Can it be used in combination with resin?

A: Yes, but it is recommended to choose a high-temperature resistant resin system for use.

6. Summary

High silica fiberglass yarn is a high-quality inorganic fiber material with high temperature tolerance, chemical stability and environmental friendliness. It has a wide range of applications in aviation, military industry, power, welding, construction and other fields, and is an ideal basis for protection and insulation materials under many high-temperature working conditions.If you are looking for high-quality high silica fiberglass yarn, our products are the right choice.
