High Temperatur Glass Threads 700°C

E-Glass Sewing Threads, up to 700 °C

As early as 1930, the first large-scale industrial application of E-glass fibre was the insulation of electrical conductors subjected to high temperatures. E-glass thread is the most used, whether in the textile industry or for composites, its share reaching 90 % of reinforcements. A high-end fibre, it is characterised by its resistance to continuous high temperatures of up to 550 °C and its excellent electrical insulation properties. E-glass fibre is rot-proof, can withstand the main chemical agents and remains dimensionally stable, even under intense variations of humidity and temperature. 

The flexibility of E-glass fibre permits the design of high-strength sewing yarns for the production of thermal protection systems or thermal, dielectric or chemical insulation solutions. Glass fibre sewing yarns are impregnated with PTFE, in order to simplify production. This coating deteriorates at high temperatures, leaving the glass fibre strands exposed.
