Bio-soluble fibers

Isowool BSSR is highly acid resistant alkaline earth silicate (AES) wool, which is a bio-soluble fiber (BSF), manufactured by Isolite unique production technology to respond to the growing demand for environmental improvements.

This fibrous material is exempt from the regulations of the International Agency for Research on Cancer (IARC), EU Directive (97/69/EC), and the German Technical Rules for Hazardous Substances (TRGS 905).

If your workplace environment needs to be improved, Isowool BSSR is an excellent alternative to RCF, depending on your equipment and operating conditions. Isolite in cooperation with our business partner Unifrax could provide Isofrax and Insulfrax both bio-soluble fiber.(Please contact our sales representative)
