Sheet Insulations – Nomex and Varnished

Nomex Aramid Paper

Inherent Dielectric Strength – Depending on the product type and thickness, Nomex will withstand short term electrical stresses of 18 to 40kV/mm with no need for further treatment with varnishes or resins.

Mechanical Toughness – Nomex products are strong, resilient and (in the thinner grades) flexible, with good resistance to tearing and abrasion.

Thermal Stability – Temperatures up to 200°C have little or no effect on the electrical and mechanical properties of Nomex. Even with continuous exposure at 220°C for 10 years or more, Nomex still retains useful values.

Chemical Compatibility – Nomex is essentially unaffected by most solvents and is usually resistent to attack by acids and alkalines. It is compatible with all varnishes, resins, oils and fluorocarbons and is impervious to attack by insects, fungi or moulds.
