Latest company news about New Choice for High-Temperature Protection: Calcium Silicate Coated Fiberglass Fabric—The "Industrial Armor" Withstanding 700°C

In modern industry, safety protection in high-temperature environments is crucial. Whether in welding workshops with flying sparks or power plants with roaring turbines, a material that can withstand extreme heat while remaining durable is essential. Today, we introduce a star product in high-temperature protection—calcium silicate coated fiberglass fabric—a true "industrial armor" with outstanding performance.

1. What Is Calcium Silicate Coated Fiberglass Fabric?
This material is a composite fabric made by coating fiberglass cloth with calcium silicate, a high-temperature-resistant inorganic compound. Fiberglass itself offers high strength and corrosion resistance, while the calcium silicate coating boosts its heat resistance to 700°C, along with enhanced abrasion resistance, chemical corrosion resistance, and anti-aging properties.

2. Why Can It Withstand Extreme Heat?
High-Temperature Resistance: Calcium silicate has an extremely high melting point, effectively blocking heat transfer and protecting underlying materials.

Abrasion Resistance: The coating increases surface hardness, making it ideal for high-friction industrial applications.

Chemical Resistance: Resists acids, alkalis, and other corrosive substances, extending service life.

Anti-Aging: Maintains integrity even under prolonged exposure to heat or outdoor conditions.

3. Four Key Features: A Versatile Solution for Industry
Thermal Insulation & Fireproofing: Used as welding blankets to block sparks or as insulation wraps for turbines and pipelines.

Customizable Options: Available in thicknesses from 1.0mm to 2.0mm and colors (blue, white, gray, green) for easy identification.

Eco-Friendly & Safe: Inorganic composition ensures no toxic emissions under high heat.

Cost-Effective & Durable: Lighter and more economical than traditional metal shielding.

4. Typical Applications
Welding Protection: Covers work areas to prevent fire hazards from sparks.

Energy Equipment: Insulates turbines, boilers, and pipelines to reduce heat loss.

Chemical Industry: Acts as sealing or barrier material in corrosive environments.

5. Did You Know? Calcium Silicate vs. Graphite Coating
While similar in performance to graphite-coated fiberglass, calcium silicate coating offers more color options (graphite is typically black) and better oxidation resistance, making it ideal for applications requiring material differentiation.


With its unmatched heat resistance, durability, and longevity, calcium silicate coated fiberglass fabric is steadily replacing traditional protective materials. Whether for industrial safety or energy efficiency, it’s an indispensable "invisible shield." Next time you see blue or gray welding blankets in a workshop, remember—this might be the "tech armor" even 700°C heat can’t breach!
