Nomex® Type 414 is designed for applications requiring a strong, yet flexible and conformable sheet. It is electrically and thermally similar to Nomex® Type 410, but is calendered under different conditions to provide its unique properties.
Nomex® Type 414 is produced in five thicknesses (0.09 to 0.38 mm) (3.4 to 15 mil), with a density from 0.9 to 1.0. Nomex® Type 414 was designed for use as slot insulation in hand-wound motors and for linear wrapping of wire. Visit our video channel to learn more about Paper Type Roll!
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 mil) to 40 kV/mm (1015 mil), 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
- Nomex� 414 is designed for use as slot insulation in hand-wound motors, for linear wrapping of wire, and as main insulation for dry-type transformers where conformability and impregnability are required
- 91 (machine direction of paper), 45 (cross direction of paper) initial tear strength
- 21# (machine direction), 9.4# (cross machine direction) tear resistance
