Nomex® Paper Protects Critical Components in Electronic Applications
DuPont™ Nomex® brand paper has a long history of proven performance in motors, generators and transformers. Now, it is gaining a reputation as an ideal choice for battery packs and electronic applications.
From mobile phones and tablet computers to flat-screen liquid crystal display (LCD) televisions, Nomex® paper is helping to protect critical components in a wide range of electronic applications. A prime example is the use of Nomex® paper in LCD televisions as the insulation barrier, or “firewall,” between the power module board and the cover plate.
In some cases, Nomex® paper is used in electronic applications to enhance performance. For example, Nomex® paper is used as a diaphragm suspension damper in the micro speaker of smart phones to improve sound generation. The use of Nomex® paper enables a broader range of sound in both low and high frequency.
The Nomex® 200 Series is specifically designed to meet the market requirements for battery packs and electronic applications. Nomex® 200 Series papers:
- Fulfill Underwriters Laboratories (UL) 94 V-O requirements.
- Provide excellent tear and puncture resistance.
- Feature thermal stability at temperatures up to 392°F (200°C)—which far exceeds this market’s need for 248°F (120°C).
- Offer chemical compatibility with all classes of varnishes and adhesives, and are unaffected by lithium ion battery electrolyte leaks.
- Enable easy processability.
