U.S. DuPont NOMEX? Aromatic polyamide paper who require electrical insulation is usually able to see of NOMEX? Aromatic polyamide product, it has a unique and appropriate balance of performance, over the years, is widely used in transformers, motors, generators and other electrical equipment to improve the reliability of electrical insulation. unique combination of properties of NOMEX? product has excellent properties of NOMEX? is a synthetic aromatic amide polymers, with the following excellent features: 1. inherent dielectric strength After the pressing process of NOMEX? product capability 18 ~ 40KV/mm short-term voltage field strength, without the need for further treatment with varnishes and resins; Because of NOMEX? product has a low dielectric constant, thus making the insulation and cooling medium electric field distribution is more uniform; of NOMEX after mechanical toughness calender? very high strength and elasticity, good tear resistance and abrasion resistance, thinner products with flexibility; thermal stability NOMEX ? recognized by the UL material temperature rating of 220 ° C, on behalf of consecutive placed 220 ° C, the effective performance can be maintained for more than 10 years; the chemical compatibility of NOMEX? independent of the impact of most of the solvent, and very acid, alkali corrosion, it is also compatible with all varnishes, adhesives, transformer fluids, lubricating oil and the cold Frozen agent, NOMEX? will not be insects, fungi and mold damaged; 5. low temperature performance in the boiling point of nitrogen (77K ) of NOMEX? the T410 type of insulation paper and of NOMEX? 993,994 laminate tensile strength in excess of the intensity values ??at room temperature; 6 is not sensitive to moisture of NOMEX? products in the phase degree of humidity 95%, the dielectric strength 90% of the completely dry state, at the same time, many of the mechanical properties is actually an improvement; radiation-resistant even to ionizing radio intensity up to 800 MB Ladd (8 trillion Gy) of NOMEX? products basically do not affected, but still to maintain its mechanical and electrical properties after 8 times of such doses of radiation; 8. toxic / flame of NOMEX? products will not be no known human or animal toxicity of NOMEX? products in the air does not melt, not combustion. and limiting oxygen index (LOI) at 220 ° C greater than the combustion critical value of 20.8 (usually empty), so it will not burn. of NOMEX? products comply with UL 94V-0 flammability requirements prescribed
