SynTherm® – Insulating Materials

Nomex® 410

Nomex® 410 is a synthetic electro-insulation paper constructed of a calendered, aromatic polyamide fibride flock composition.

Attributes

Nomex® 410 is a Class H (180 °C) insulating material. Temperatures below 200 °C only slightly influence its electrical properties. The excellent mechanical properties can be extrapolated at much higher temperatures. Due to the polymer structure, Nomex® 410  can also be used at temperatures as low as -190 °C.

It has a high short-term dielectric strength; nevertheless, the permanent dielectric strength should not exceed 1.2 kV/mm. Nomex® 410 is compatible with all common resins, varnish, adhesive classes, as well as transformer liquids, oils and cooling agents. Common solvents may lead to slightly reversible moisture expansion. Nomex® 410 has a low flammability (UL 94V-0), moreover, it displays a very high level of beta and gamma-ray resistance.

Application

High quality Nomex® 410  is used in almost all known applications for electrical insulating materials. Application ranges from AC and DC motors to large generators, wet and dry transformers and chokes, even with beta and gamma radiation exposure.

Standards
  • Class H (180 °C) insulating material.
  • UL listed (RTI mech. + elect. 220 °C)
  • RoHS compliant according to 2011/65/EU
Delivery forms

Film thickness in µm:
50, 80, 130, 180, 250, 300, 380, 510, 610, 760

Nomex® 410 can be supplied:

  • in slit rolls: depending on the material thickness
  • in rolls: 457 mm or 914 mm


Feathering:

  • depth approx. 1 - 12 mm, distance approx. 1 - 10 mm
  • from widths of 10 to 240 mm and thickness of 0.25 mm
Base

Calandered aromatic polyamide fibride composition.

Corona information, 31.03.2020

Dear business partners,

Despite the progressing corona pandemic, we as SynFlex have succeeded to date in maintaining our business operations at all locations. We offer our customers the accustomed high level of service in terms of delivery flexibility and advisory competence and we maintain existing agreements with our suppliers. Our staff currently provide excellent services despite the many precautionary measures necessary to protect everyone's health. They are fully available to you, in administrative areas usually from a home office.

It remains to be seen how things will continue. Crisis management dominates. It is simply impossible to make serious forecasts about future economic and social changes. All forecasts are plain guessing.

Thus, the resolutions remain: maximum solidarity, responsible action and best possible maintenance of all structures. There will be a time after SARS-CoV-2!

In this spirit we wish you all much steadfastness and good health.

Your SynFlex Team
