Isofrax®-1400 thermal insulation from Unifrax belongs to the last generation of the proven, groundbreaking technology for low bio-resistant fibers. Isofrax1400 blanket is manufactured using modern defibration techniques combined with a new proprietary processing technique, which means that both a classification level of 1400 and a higher application temperature limit for
Applications up to 1300 ° C is offered. The needled mat is completely inorganic and retains its strength, flexibility and thermal properties without generating smoke in many work environments. Isofrax 1400 blankets are available in a variety of density and thickness combinations and can be used in a variety of high temperature applications.
- High temperature stability
- Low thermal conductivity
- Resistance to temperature changes
- Light weight
- Good workmanship
- Low heat storage
- Excellent flexibility
Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers, which are melted and then rapidly solidified using a combination of silica SiO2 and calcium oxide (CaO) with or without magnesium oxide (MgO). The fiber can be obtained by refining with other additives or a change in the material mix (addition of zirconium oxide (ZrO2) have a temperature resistance of up to 1260 ° C.
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.
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.
We manufacture molded parts according to your specifications. The roll goods are made using
