General Description:  

General Description : An infusible, wholly aromatic polymer that can strictly be described as nylon I,I - but rarely is. Manufactured only as a fibre (by solution spinning), it has a very high thermal stability andtemperature and flame resistance. In contrast to its chemical isomer DuPont™ Kevlar®, its tensile properties are similar to those of normal textile fibres but its hydrolysis resistance in hot wet conditions is better(than DuPont™ Kevlar®). Its radiation resistance is also very good.

The fibre is converted into a number of fibre-based forms, including : calendered and uncalendered papers, pressboards of three different densities and honeycomb. The last is made from DuPont™ Nomex® paper coated in a phenolic resin. Other forms include felts.

Applications include protective clothing (e.g. for firefighters andracing drivers), process equipment and insulation and filtration media.
