Superwool fibre is a high-temperature insulating wool composed of man-made vitreous silicate fibres. Each fibre grade features its own unique attributes and benefits to meet the demands of your application. The low biopersistent, alkaline earth silicate and potassium aluminosilicate, marketed as Superwool insulating fibres have been engineered to offer advantages in high temperature insulation applications.
Traditional Refractory Ceramic Fibre (RCF) is a highly versatile material. It can be spun or blown into the product forms as seen in the table.
The polycrystalline fibres (PCW) are made from high alumina (>95% alumina) or mullite fibres (85% alumina) using the Sol-Gel process. These fibre solutions are ideally suited for many challenging atmospheres and feature a temperature rating up to 1600°C (2912°F) with very low linear shrinkage and excellent resistance to alkali and chemical attack.
