HomeHIGH TEMPERATURE SILICA YARN

HIGH TEMPERATURE SILICA YARN

Domadia™ High-Temperature Silica Yarn is an advanced insulation material engineered for extreme thermal environments. Manufactured from continuous filaments (ranging from 5 to 9 microns in diameter per filament), this yarn exhibits the thermal performance of refractory materials. With an exceptional continuous working temperature of 1000°C (1800°F), it provides superior resistance to thermal shock, low thermal conductivity, minimal shrinkage, and excellent performance under cyclic thermal loads.

This high-performance silica yarn is chemically treated and thermally stabilized, ensuring exceptional durability, tensile strength, and electrical insulation properties. Compared to E-Glass and Basalt fibers, High-Temperature Silica Yarn exhibits superior resistance to acids and alkalis (up to pH 14), making it an ideal choice for industrial applications requiring high chemical resistance, thermal stability, and minimal fiber degradation
