Glass Fibre Felt 700°C
E-Glass Fibre Felt, up to 700 °C
E-glass fibres are the most widespread in use, whether in the textile industry or for composite materials, and are present in 90 % of reinforcements. This high-quality fibre is distinguished by its resistance to high temperatures and its excellent electrical insulating properties. This fibre is rot-proof, resistant to the most common chemical agents and dimensionally stable, even in the event of substantial variations in humidity and temperature.
Needled fibreglass felts are made of thermally stable, cut E-glass fibre. This felt has excellent mechanical, chemical and dielectric properties. In addition, it can withstand a continuous temperature of 550 °C, and can be reinforced with a layer of aluminum to withstand radiant heat up to 1,650 °C. They are mainly used in the naval and automotive industries for thermal and acoustic insulation.
E-glass filaments of diameter exceeding 9 μm can cause skin irritations. For this reason, E-glass fibre cords supplied are produced from textured and twisted strands of diameter ranging from 6 to 9 µm.
These e-glass products complement Newtex’s product range.
