Lamtuf Plastics Ltd. - Products - Fabric Sheets

Grade	NEMA - CE

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

Thickness	0.025" - 2"

Description	Grade CE is intended for use in electrical application requiring good Moisture resistance and good mechanical strength. It has lower Mechanical strength than material with glass substrates, but has superior Impact resistance when compared to paper based products. This material is not as suitable for fine machining as LE .CE possess Fairly good dielectric properties and medium dielectric loss.

Size	1220 x 1220 (48" x 48") / 1440 x1220 (96" x 48") (With an extra margin Ľ" on both the sides)

Tolerances	Tolerance as per NEMA STANDARD
