Polyimide Yarn: The Future of High-Temperature Textiles | DOMADIA™
Introduction: When Ordinary Threads Fail, Polyimide Yarn Prevails
In a world where machines run hotter, vehicles go faster, and industries demand stronger materials — traditional textiles often melt under pressure (literally!). That’s where DOMADIA™ Polyimide Yarn steps in — a next-generation fiber built to thrive in environments where others burn out.
From aerospace to electric insulation, polyimide yarn is redefining how industries think about durability, flexibility, and heat resistance. Let’s explore why it’s not just another material — but a textile revolution in motion.
What Is Polyimide Yarn?
Polyimide Yarn is a high-performance synthetic fiber spun from aromatic polyimide polymers. These polymers contain imide groups (–CO–NH–CO–) that form strong molecular bonds, resulting in exceptional thermal and chemical stability.
Unlike regular fibers that degrade under heat, DOMADIA™ Polyimide Yarn can withstand continuous exposure up to 260°C, and even short bursts up to 400°C, making it ideal for high-temperature environments.
Chemical Composition
- Base Polymer: Aromatic Polyimide (from biphenyl tetracarboxylic dianhydride & oxydianiline)
- Structure: Fully aromatic heterocyclic rings for superior stability
- Melting Point: No melting point (it decomposes above 500°C)
- Flammability: Self-extinguishing (UL94 V-0 rated)
- Color: Naturally golden yellow, can be customized
