From a chemical point of view, NOMEX insulation paper is a kind of aromatic polyamide, collectively known as aromatic polyamide.
The molecular structure of the material is particularly stable, and the performance of NOMEX paper is generated.
NOMEX insulation paper is made from a polymer of two types of aromatic polyamide.
The small fibrous bond particles are cut directly from the polymer under high shear action.
These particles are mixed with short fibres of a certain length cut from the filaments.
Where the need to electrical insulation, often can see NOMEX ® aromatic polyamide products.
It has a unique and appropriate performance balance and has been widely used in transformers, motors, generators and other electrical equipment for years to improve the reliability of electrical insulation.
