Product Description Color Features Recommended Applications Milspec Recognized in U.L. Systems
DM-70 Combination of polyester mat on both sides of polyester film.  Mat is approximately 70% saturated. White The polyester film provides a dielectric barrier while the polyester mat increases physical properties such as initiated edge tear.   The mat surface absorbs varnish well, increasing the bonding of all components.   Good chemical resistance. Phase insulation for motors and generators.

Ground, barrier, and layer insulation for dry type transformers.

Memco 100 Same as DM-70 except both sides fully saturated with an epoxy resin. Red, Blue, or White Both sides of DM-70 are fully saturated with a hermetically stable epoxy resin to impart smooth, abrasion resistant surface. Slot liner, wedge, and phase insulation for motors and generators. MIL-I-22834

This guide describes the most commonly used flexible composite materials, but is by no means a complete listing of our capabilities.  We solicit your inquiries for any flexible composite you require.

Thicker combinations are recommended for slot and ground applications whereas thinner combinations are recommended for phase and layer applications.
