New Products / Refractories


Superwool® HT™ Felt and Superwool HT™ Millboard are reportedly ideal for fabricating gaskets and heat shields for industrial appliances, including ovens, fryers, and cooking equipment. The lightweight, multi-purpose products are available in a range of sizes, thicknesses and densities, and can offer equivalent performance to traditional refractory ceramic fiber (RCF) insulation in many applications.

As global regulatory restrictions on RCF are being tightened, many manufacturers of industrial appliances around the world are seeking to move toward insulation alternatives. Superwool fiber has been developed to provide the improved high-temperature characteristics required to act as an alternative to RCF. Rigorous testing has established that Superwool fiber products feature low bio-persistence, and felt and millboard made from Superwool fiber are fully exonerated from any carcinogenic classification under nota Q of directive 97/69 EC issued by the European Union. They are not restricted by European REACH (Registration, Evaluation, Authorization and Restriction of Chemical substances) regulations.
