DOMADIA™ Basalt Yarn
DOMADIA™ Basalt Yarn
Next-Generation Fiber for Strength, Safety & Sustainability
Introduction
Elevate your product performance with DOMADIA™ Basalt Yarn—a high-performance technical fiber engineered from natural volcanic rock. Designed for extreme durability and thermal endurance, this eco-friendly yarn is redefining how industries approach reinforcement, insulation, and composite manufacturing.
About the Product
DOMADIA™ Basalt Yarn is a continuous filament yarn produced by melting and extruding pure basalt rock. Unlike synthetic fibers, it is made without chemical additives or coatings, making it naturally fireproof, non-toxic, and corrosion-resistant. The result? A superior, multi-functional fiber trusted across sectors like construction, automotive, aerospace, marine, and industrial textiles.
Key Features & Advantages
- Superior Strength-to-Weight Ratio
Offers excellent tensile strength, making it ideal for structural applications that demand high mechanical integrity.
- Thermal Resistance up to 800°C
Performs reliably in high-heat environments where traditional fibers degrade.
- Chemical & Corrosion Resistance
Maintains stability in alkaline, acidic, and saline conditions—perfect for marine and construction uses.
- Eco-Conscious & Safe
Made from 100% basalt rock—free of toxins, non-flammable, and safe to handle.
- Electrical Insulation Properties
Delivers excellent dielectric performance for industrial and electrical insulation.
- Minimal Shrinkage
Retains shape and strength under thermal cycling and mechanical stress.
