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 fiber (by solution spinning), it has a very high thermal stability and temperature and flame resistance. In contrast to its chemical isomer Kevlar®, its tensile properties are similar to those of normal textile fibers but its hydrolysis resistance in hot wet conditions is better (than Kevlar's). Its radiation resistance is also very good.

The fiber is converted into a number of fiber-based forms, of which the following are available from Goodfellow's stock : calendered and uncalendered papers, pressboards of three different densities and honeycomb. The last is made from Nomex® paper coated in a phenolic resin. Other forms, eg felts, can be available as special orders.

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