Industrial
Laminates, NEMA G-5/G-9, G-7
|
| G-5 and G-9 are
composed of a continuous woven glass
cloth base impregnated with melamine
resin, which is the hardest, most
rigid and abrasion resistant of the
resins used for industrial laminates.
They are normally gray in color and
exhibit good dimensional stability and
arc resistance. However, prolonged
exposure to elevated temperature can
adversely affect these industrial
laminates' mechanical and electrical
properties. G-9 is the more resistant
to environmental conditions of these 2
grades. G-7 is also composed of a
continuous woven glass cloth base, but
with a silicone resin binder. G-7 has
excellent heat and arc resistance, so
it is used for electronic parts
exposed to high temperature. |
