ALUMINIZED FABRIC SAMPLES

Different flame-retardant fabric compositions are used as the base for aluminised fabrics, depending on the final application of the laminate: thermal barriers, gaiters for steelmaking, furnace curtains—these are some real examples of applications of Texfire’s aluminised fabrics. The aluminised fabrics we can find are as follows:

• Aluminised fabric EGLA 200 AL: This is an E-glass fibreglass fabric weighing 200 gsm with a 12-micron aluminium film. Its aluminised side acts as a thermal shield, blocking radiant heat and improving insulation against convective heat or flames. It offers dimensional stability, as well as mechanical and thermal resistance, withstanding continuous temperatures of up to 450ºC and peaks of 550ºC.

• Aluminised fabric EGLA 430 AL: This is a flame-retardant fibreglass material with a 12-micron aluminised layer. It has a thickness of 0.4 mm, a total weight of 450 g/m², and withstands continuous temperatures of 450°C and peaks of 550°C. Its aluminised layer acts as a thermal shield, offering protection against radiant heat and direct flame contact.

• Aluminised fabric WELS1 ALP: It combines aluminised fibreglass on one side, impregnated with aluminium particles, and a high-temperature-resistant silicone coating on the other. The silicone repels sparks and molten metals, while the aluminised side protects against radiant heat. This special design provides greater flexibility and durability compared to conventional aluminising. Furthermore, it is lightweight and impervious to liquids and fumes.

• Aluminised nonwoven nt preox 500AL: This is a nonwoven made of pre-carbonised polyacrylonitrile (PPAN) fibres, with a 12-micron aluminium layer. Preox fibres provide high fire resistance and excellent thermal insulation, with a LOI index close to 40. The aluminised side acts as a thermal shield against convective and radiant heat or flames. It has a thickness of 4.5 mm, a weight of 500 g/m², and offers great flexibility and adaptability.

• Aluminised fabric paratex 460 ALP: Composed of para-aramid fibres with a herringbone weave, it provides flexibility and inherent fire resistance. Its powdered aluminium layer maintains the fabric’s adaptability and prevents cracks or delamination. It is resistant to abrasion, cutting, vibrations, and temperatures of up to 400°C. The aluminised side serves as a thermal shield against radiant and convective heat, and also protects against UV rays.

• Aluminised thermal shield fabric altox 450: It is flame-retardant and acts as a thermal shield against flames and high temperatures. It combines aluminised fibreglass on one side with a layer of NT Preox 200 nonwoven, which enhances thermal insulation and bolsters its function as a thermal barrier. Its multi-layer design makes it especially effective in protecting against extreme heat and direct flame sources.

• High-temperature fabric silica 180 AL2: This is an aluminised flame-retardant fabric on both sides, designed to withstand extreme heat. Its core, made of mineral fibres with 95% silica, grants it high thermal resistance, allowing it to maintain its structural integrity at temperatures of up to 850°C.

• High-temperature fabric silica 300 AL: It withstands continuous temperatures of up to 850°C without losing its structural integrity. It incorporates a 12-micron aluminium foil on one of its sides, providing additional protection.
