15/12/2005 Superwool is the first low-biopersistent fibre with a classification temperature up to 1300°C Thermal Ceramics has developed the first low bio-persistent insulation fibre with a classification temperature up to 1300°C, Superwool 607 HT. The fibre - which has been developed for high temperature applications in iron and steel, ceramic, glass, incineration, aluminium production and heating boilers – offers lower shrinkage than comparable insulation fibres. This eliminates gaps or ‘hot spots’ in furnace linings, reducing costs associated with maintenance and replacement material. Superwool 607 HT is exonerated from carcinogen classification under the provisions of the EU Directive 67/548/EEC. As a result, manufacturers can reduce costs associated with meeting increasingly stringent health and safety regulations without compromising on thermal performance. Ron Wainwright, Global Technical Director at Thermal Ceramics, said: “Superwool 607 HT offers the first high performance, economical alternative to RCF. Its development is part of our commitment to provide the high temperature insulation markets with low bio-persistent fibres.” Superwool 607 HT is a high temperature insulating wool composed of man-made silicate fibres. The patented technology is available in a variety of forms including bulk, blanket, boards, felt, paper, vacuum-formed, pyro-logs, pyro-blocs, z-bloks and mastic products. Read more latest news
