Nomex®: Nomex® is a Dupont® aromatic polyamide with an operating temperature range over 220 degrees centigrade and with superb high voltage breakdown. It is an excellent choice for standardization since it outperforms many other materials. The paper is used in electrical laminates such as circuit boards and transformer cores as well as fireproofing materials. Nomex Type 410 paper is the original and one of the larger grade types made, mostly for electrical insulation purposes.

Formex™:  Outstanding dielectric strength properties. Patented materials are easily fabricated to provide low-cost solutions.

May be used as a substrate with metal lamination for EMI/RFI shielding.

Formex™ materials offer superior protection due to high dielectric strength, physical strength and flexibility.

Supplied in rolls or sheets that can be printed and will accept adhesives.

Formex’s unique material properties meet global standards for flame retardancy and chemical resistance.

The structural integrity of Formex™ materials provide new and unique options for the design and construction of low-cost internal mechanical components.

Fabricated internal parts such as air-flow baffles and wire-harness organizers are commonly used as cost-effective replacements for plastic injection-molded or sheet metal components.

No other flame retardant, electrical insulating material can match the flexibility and performance of Formex™ for cost-effective fabricated parts. Formex™ has successfully replaced a variety of electrical papers, thermoplastic materials, and injected molded parts.

PTFE: Products made with DuPont™ Teflon® fluoropolymer resins have exceptional resistance to high temperatures, chemical reaction, corrosion, and stress-cracking. The mechanical toughness, electrical, and low-friction properties of Teflon® make it the preferred plastic for a host of applications and different processing techniques.

PTFE Sheet is a specially important engineering plastic because of its outstanding lack of friction and slippiness, this is so incredibly low that is has been described as being the most slippy solid material known to man and PTFE Sheet can be cut into strips and can offer a massive improvement in the sliding components. PTFE is also highly specified due to its very high temperature resistance allowing components to withstand almost double that of other types of engineering plastic. PTFE Sheet has the capability to also withstand very strong acids and chemicals helping to provide solutions to acid storage and chemical problems. High electrical resistance is yet another feature of PTFE Sheet and PTFE is often used in high end electrical resistance appliances.
