Description

NOMEX insulating paper is a kind of aromatic polyamide, collectively known as aramid. The molecular structure of the material is particularly stable, and the properties of NOMEX paper are derived from this. NOMEX insulating papers are made from a polymer of two forms of aramid. Fine fibrous cohesive particles chromatographic fibers are cut directly from the polymer under very high shear. These granules are mixed with lengths of short fibers cut from the filaments. Wherever electrical insulation is required, NOMEX® aramid products are commonly found. It has a unique and appropriate balance of properties and has been widely used for many years in transformers, motors, generators and other electrical equipment to improve the reliability of electrical insulation.
