The Saffil® 72 Range is a family of premium polycrystalline wool (PCW) insulation products engineered for continuous operating temperatures up to 1600°C. Manufactured from high-purity mullite fibres containing approximately 72% alumina and 28% silica, Saffil 72 products provide exceptional thermal stability, chemical resistance and insulation performance in applications where conventional ceramic fibre and AES insulation materials reach their operating limits.
Designed for demanding thermal processing environments, Saffil 72 products deliver extremely low thermal conductivity, outstanding resiliency and excellent dimensional stability at elevated temperatures. Their high fibre content and low shot levels ensure consistent performance, enhanced insulation efficiency and reliable long-term operation in extreme heat-processing applications.
Available in multiple formats and densities, the Saffil 72 Range provides tailored solutions for iron and steel production, ceramics manufacturing, petrochemical processing, aerospace applications and advanced thermal management systems.
Saffil 72 products deliver exceptional performance in the most demanding high-temperature insulation applications.
