PRODUCT TYPE
Mats (blankets) made of high temperature wool are needled light mats of ceramic (ASW/RCF) High Temperature Wool (HTW) and provide an effective solution for a wide range of thermal insulation applications. They are characterised by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore do not generate smoke or fumes when exposed to heat. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.
MATERIAL
High temperature wool made of ceramic fibers, also known as ASW (aluminum silicate wool) or RCF (Refractory Ceramic Fiber), have been used for years as the standard fiber type for insulation solutions up to 1250 ° C. Consisting of a mix of aluminum oxide (Al2O3) and silica (SiO 2)2), the fibers offer not only high temperature resistance but also good chemical and mechanical properties.
UNIFRAX®
Unifrax® is one of the world's leading manufacturers of high-performance specialty fibers and inorganic materials that are used in industry, the automotive sector and fire protection. Our goals, philosophy and values build on our efforts to manufacture high quality products that help our customers save energy, reduce pollution and improve fire protection.
Product Variations
Roll goods
Fiber mats are sold as roll goods as standard. The roll length depends on the selected thickness. As a standard width, we have 610mm wide rolls from stock. Double widths are available on request.
