DuPont™ Mylar® Polyester Film

arrow right

Mylar® is a heat-resistant polyester film that combines dielectric strength with moisture resistance. When used as an insulation it is flexible and will not become brittle during normal use. Can be used as an electrical insulator over a wide range of temperatures, and resists most chemicals.

DuPont™ Nomex® 410

arrow right

Nomex® 410,  the original form of Nomex® paper, is widely used in a
majority of electrical equipment applications. It offers high inherent dielectric strength, mechanical toughness, flexibility and resilience. Available in 11 thicknesses ranging from 0.05 mm to 0.76 mm (2 mil to 30 mil).

ITW Formex® GK

arrow right

Formex® GK is a flame retardant polypropylene barrier material engineered to provide superior electrical insulation in industrial and consumer electronic equipment. The insulating material is available in rolls and sheets and can be easily fabricated into a wide range of parts. Complies with UL 94 V-0, CSA, IEC, RoHS and WEEE and can be used in service temperature up to 115°C

Lydall® LyTherm® 550L

arrow right

An easy-to-cut, lightweight utility paper processed from unwashed spun, high-purity alumina-silica fibers formed into a highly flexible sheet. Makes an excellent thermal and electrical insulator. Recommended for continuous use at temperatures up to 2300°F (1260°C) in applications where insulating efficiency is not critical.

Lydall® LyTherm® 970

arrow right

A lightweight, binderless commercial-grade paper composed of a refractory material processed from washed, spun, high purity alumina-silica fibers formed into a highly flexible sheet. It is recommended for continuous use at temperatures up to 2300°F (1260°C) in applications where insulating efficiency and high strength are important and where off-gassing of organic binder cannot be tolerated.

Lydall® LyTherm® 1530

arrow right

A lightweight, premium grade paper composed of a refractory material processed from highly washed, spun, high purity alumina-silica fibers formed into a flexible sheet. Formulated to minimize unfiberized particles, LyTherm 1530 paper offers an extremely low thermal conductivity and a dust-free surface. Recommended for continuous use at temperature up to 2300°F (1260°C) in applications requiring high strength, resiliency, and excellent thermal properties.
