What is Nomex®?

Nomex is an aramide paper which is used as an electrical insulating material. We manufacture slot insulations, slot closures, die-cut and formed parts as well as adhesive tapes and similar from Nomex.

Generally Nomex 410, Nomex 411 and Nomex 414 are used for these kinds of applications.

Which Nomex models are available at Dr D. Mueller?

Dr D. Mueller GmbH provides Nomex 410, Nomex 411, Nomex 414, Nomex 993 and Nomex 994.

Can Nomex-papers be die-cut?

Nomex 410, Nomex 414 und Nomex 411 can be die-cut with common die-cutting processes. Steel rule dies, complete cuts and rotative tools can be used for die-cutting of Nomex 410, Nomex 414 und Nomex 411.

Can Nomex be lasered?

All Nomex types can be laser cut. This includes especially the Nomex model 410.

Is Nomex also available as self-adhesive alternative?

Nomex is available as adhesive tape. Nomex can also be covered with transfer adhesive by our company.

Can Nomex be ultra-sonic welded?

Nomex can be ultrasonic-welded. Often Nomex 410 is welded to ribbed mats with Nomex 994 for the transformer construction. 

What is about the delivery time for Nomex?

Most of the Nomex models are available ex works. If we do not have some models ex works, we can get them short-timed.

Where can Nomex be bought?

Nomex can be bought at Dr D Mueller GmbH. To buy it, please send us an inquiry.

Can Nomex be imprinted with a laser printer?

Nomex can be imprinted with common laser printers.

What is the relative dielectric constant (Permittivity) of Nomex 410?

The relative dielectric constant (Permittivity) of Nomex 410 at 60Hz / 100kHz is 1.6 (0.05 and 0.08) or 1.8 at other thicknesses.

Which models of Nomex 410 are available?
