Nomex 410

This is a commonly used Nomex paper. If no part number is specified, this 410 will be used.
After the papermaking process, the product is calendered (compressed at high temperature and high pressure) to increase density.
It has stable electrical properties that are not affected by temperature changes up to 250°C and relative humidity changes up to 95%. It has excellent heat resistance certified by UL standards for continuous use at 220°C.
It is flame retardant, and products over 5mil (0.13mm) have passed UL standard 94V-0.
We offer thicknesses from 0.05mm to 0.76mm (2mil to 30mil).
It is resistant to various chemicals and solvents, and is compatible with insulating oils and solvents.

Nomex 411

This material is not calendered after the papermaking process. It has a relatively low density, is highly flexible, and has excellent surface absorbency. It is absorbent, has good impregnation and resin retention, and is also suitable for use as interlayer insulation in resin casting applications.
It is flexible, so it can be drawn like paper containers, and can be processed into various shapes depending on the maturation type.
It has excellent heat resistance, certified by UL standards for continuous use at 220°C.
It is resistant to various chemicals and solvents, and is compatible with insulating oils and solvents.

Nomex 414

Like 410, it is calendered after the papermaking process, but the conformability has been improved.
The electrical and mechanical properties are compatible with 410, but it is easier to draw and thermoform, which are not possible with 410.
Type 414 has a particularly high initial tensile strength in the lateral direction of the tear, so it is necessary to set the processing direction to make the most of this property.

In addition to the above, we also have Nomex 356 (an intermediate grade between 410 and 411) and Nomex 818 (a grade containing mica).
