Nomex 464LAM

Nomex 464 LAM is a lightweight paper compared to Nomex® 416 LAM, but is intended for the same use in electrical flexible laminate insulation.
It is available in 0.05 mm (2 mil).
Similar laminate constructions can be found in the market, with either polyester film or polyimide film, depending on the thermal requirements of the application.

Nomex 464LAM Features

Exceptional thermal stability—Temperatures up to 200°C have little or no effect on the electrical and mechanical properties of Nomex®, and useful values are retained at considerably higher temperatures. What’s more, these useful properties are maintained for at least 10 years of continuous exposure at 220°C.
Outstanding mechanical toughness—Densified Nomex® products are strong and resilient with good resistance to tearing and abrasion. Thinner grades are also flexible.
Inherent dielectric strength—In densified form, Nomex® withstands short-term electrical stresses of 18 kV/mm (457 mils) to 40 kV/mm (1,015 mils), depending on product type and thickness, with no need for further treatment with varnishes or resins.
Broad chemical compatibility—Nomex® is essentially unaffected by most solvents and is unusually resistant to attacks by acids and alkalis. It is compatible with all classes of varnishes and adhesives, transformer fluids, lubricating oils, and refrigerants.
Excellent flame-resistance—Nomex® products do not melt and, with a limiting oxygen index (LOI) at 220°C above 20.8 (the critical value for combustion in normal air), they do not support combustion.
