Although there is no proven evidence that RCF causes lung problems, the EU has classed it as a Category 2 carcinogen. This not only puts responsibilities on insulation manufacturers to provide an alternative insulation material, but requires employers using RCFs to seek a substitute which would present a lower risk to the health of workers. Superwool 607 launched in 1990 is now well known in the market place to replace ceramic fibres at temperature up to 1000 deg C maximum continuous use temperature. Superwool 607 HT is the first economically viable low bio-persistent insulation fibre with a classification temperature of up to 1300 deg C. Its use is recommended in blanket form for furnaces rated for continuous use at 1150 deg C, paper and vacuum formed products can work at temperatures as high 1260 deg C. Superwool 607HT is now in the market for now three years and manufacturers in various industry have already converted their RCF1260 to Superwool 607HT successfully. Manufacturers using RCF insulation can look to Superwool 607 HT to help them meet increasingly stringent health and safety regulations and reduce the costs associated with maintenance and replacement of insulation material, without compromising thermal performance.
