     Fabric Based Industrial Lamination (NEMA -Grade - LE)
GRADE NEMA - LE
COLORS

Sheets are supplied in natural colour, but can also supplied a per
requirement i.e., Dark Brown or Black Colour.

THICKNESS 0.015" -   2"
Description

Grade LE is intended for use in electrical application requiring good Moisture resistance. It has lower Mechanical strength than material with glass substrates, but has superior Impact resistance when compared to paper based products .It suitable for fine machining LE possesses  Fairly good dielectric properties and medium dielectric loss.
