Frame Resistant PET Film

Frame Resistant PET Film (e.g. Lumirror®ZV10, Hostaphan®RF) is a yellowish polyester film with free of halogen flame retardants. The frame resistance meets UL 94VTM-0. This film not only has excellent frame resistance, but also has the same superior performance as PET film such as electrical properties, dimensional and thermal stability.
Frame Resistant PET Film is suitable for use in electric motors, transformer, building and decorating materials, heating system which require high safety.

Nomex ® Paper

Type 410
is the original form of Nomex ® paper, and is widely used in a majority of electrical equipment applications. It is produced in thicknesses from 0.05 to 0.76 mm (2 to 30 mil) with specific gravities from 0.7 to 1.2. As a calendered product, it has high inherent dielectric strength, mechanical toughness, flexibility and resilience. Nomex Type 410 is used in almost every known sheet insulation application.

Type 411
is the uncalendered precursor of Nomex ® Type 410. It is available in thicknesses from 0.13 to 0.58 mm, (5 to 23 mil) with a specific gravity of 0.3 and correspondingly lower electrical and mechanical properties. It is used in applications such as motor phase insulation and transformer coil end filler, where high bulk and conformability are of prime importance along with increased impregnability and saturability.

Type 414
is electrically and thermally similar to Nomex ® Type 410, but is calendered under different conditions which produce a strong, but more flexible and conformable sheet with an open surface. It is produced in thicknesses from 0.09 to 0.38 mm (3.4 to 15 mil) with specific gravities from 0.9 to 1.0. It is designed for use as slot insulation in hand-wound motors, for linear wrapping of wire and as main insulation of fluid-filled and dry-type transformers where conformability and impregnability are required.

Type 418
Is produced by adding 50 percent mica platelets, intimately blended with the floc and fibrids during papermaking. It is available in thicknesses from 0.08 to 0.36 mm (3 to 14 mil) and is designed for high-voltage applications, including motor conductor and coil wrap, and transformer ground and layer insulation. Nomex ® Type 418 is a calendered product with high inherent dielectric strength of 30 to 40 kV/mm (760 to 1015 V/mil), but can also be readily impregnated with varnishes where this is desirable. Nomex ® Type 418 offers increased voltage endurance when compared to Nomex ® Type 410. (Download PDF)
Type 419
is the uncalendered precursor of Nomex ® Type 418. It is available in two thicknesses, 0.18 mm (7 mil) and 0.33 mm (13 mil), with a specific gravity of 0.5 for applications where conformance and saturability are required. (Download PDF)
Type E56
is a medium-density paper (specific gravity 0.7) produced in thicknesses from 0.13 to 0.51 mm (5 to 20 mil). This calendered paper has mechanical and electrical properties intermediate between Nomex ® Type 410 and Nomex ® Type 411. It offers a higher yield and therefore economically a more attractive solution in applications where it is not critical to use to the full extent the mechanical or electrical properties of Nomex ® Type 410.
