MYLAR®
TYPE A are tough, general-purpose, slightly transparent
films that retain good physical properties and low shrinkage over a
wide temperature range (-73¢XC - 149¢XC), some have the rough
surface to provide ease of handling, good adhesion, and
processibility make them have frequently used for coil insulation in
transformers and other industrial applications.

NOMEX® TYPE
410
NOMEX® Type
410 is a calendered insulation paper which have superior
property by offering high inherent dielectric strength, mechanical
toughness, flexibility and resilience. NOMEX® Type 410 is the
original form of NOMEX® paper, and is widely used in a majority of
electrical equipment applications. Available in 12 thicknesses
products(0.05 to 0.76 mm) with specific gravities from 0.7 to
1.2,which is widely used in a majority of electrical equipment
applications.

Formex®
Formex® are flame retardant grades of
polypropylene, extruded into sheet and primarily used for their
electrical insulation properties. Due to the high dielectric
strength and low moisture absorption, they can meet the insulation
requirements for most majorities of electrical equipment
applications.
