Glass Fiber Sewing Thread

High-Temperature Resistant Industrial Sewing Solution

Product Overview

High-Temperature Resistant Industrial Sewing Thread, also known as Glass Fiber Thread, is made from E-grade alkali-free environmentally friendly glass fiber through a special industrial spinning process. It is an industrial sewing thread with ultra-high temperature resistance, featuring properties such as high heat resistance, insulation, fire retardancy, corrosion resistance, aging resistance, weather resistance, high strength, high modulus, anti-static, and a smooth surface. When sewn on high-speed industrial sewing machines, it does not cause untwisting, ensuring smooth stitches, no fuzzing, and no thread breakage during sewing.

Performance Features

Excellent heat resistance: Maximum service temperature up to 600℃.
Lightweight & heat-resistant: Low heat capacity and low thermal conductivity.
Durable stability: Corrosion-resistant, aging-resistant, weather-resistant, non-hygroscopic, non-corrosive, mildew-resistant, and moth-proof.
Electrical safety: Good electrical insulation performance and anti-static property.
Sound absorption: Effective sound absorption performance, exceeding the average NRC (Noise Reduction Coefficient) requirement.

Inorganic fiber nature: Fireproof and non-combustible (Class A - non-combustible).
High mechanical strength: High tensile strength and excellent dimensional stability.
Easy construction: Can be cut and sewn according to application needs, simple to install.
