FLAME RETARDANT ALUMINIZED FABRIC THERMAL BARRIER
Flame retardant fabric WELS1 ALP is composed by an aluminized fiberglass base on one side and a silicone coating for high temperature on the other side of the fabric. The silicone coating repels sparks and projections of melted metals. The aluminized side, through an aluminium particle impregnation, brings protection against radiant heat. The main difference between this special aluminization system is that the fabric obtained is more flexible and lasting during movement cycles, compared to a conventional aluminization via a constant aluminium layer. Thus, WELS1 ALP is a light fabric, completely impermeable to liquids and fumes.
Aluminized fabric WELS1 ALP is designed mainly to perform as a thermal shield or a light thermal barrier, some clear examples of its applications are in high-speed doors of industrial furnaces or in vertical curtains. In addition, WELS1 ALP fabric also offers a great protection against molten metal spills, so then it is a very recommended fabric to be used as screens in high foundries and steel industries. It can be handled and folded without a deterioration nor marking of the fabric nor the aluminized side. It can withstand temperatures up to 300ºC in continuous work arriving to withstand up to 550ºC in working peaks, and its thickness is 0,5mm.
WELS1 ALP has been tested in internal laboratories with the following tests: ISO 9151 - Convective heat -, result B1, ISO 6942 - Radiant heat - C4, it also meets regulation EN ISO 15025 with an A1-A2 classification - Limited spread to flame -.
