Up to 80°C temperature resistant Moisture resistant Ideal for heat shielding Substitute for asbestos A Supalux board with a heat resistance of 80°C can serve as a heat shield in jewellery making for specific low-heat applications. This rectangular soldering board is made from supalux which is a non-combustible building board made from calcium silicate and reinforced with fibre and fillers. It is moisture and mold resistant making is suitable for damp or humid conditions. Versatile, this board allows you to use in various ways such as: Bench Shielding - Supalux boards can be placed on your workbench to protect it from heat during low-temperature processes, such as wax carving or low-heat soldering or used to shield surrounding areas from heat when using tools that generate mild heat.
