Abstract

A thermoformable air permeable coherent filter web contains a blend of glass wool fibres with chopped strand glass fibres together with a polymeric binder thermoformable at a temperature from 200-350 DEG F and capable of undergoing cross-linking upon heating to a temperature above 280 DEG F. The web is capable of being embossed in the dry state without cracking or splitting and is useful for making air filters.
