INSULATION
Three new PHENOLITE" electrical laminates by
NATIONAL feature superior dimensional stability,
exceptional flame retardance, unusually
low cold flow.
,Just when designers need them most, from National's
Research Laboratory come tested answers
to three of the electrical industry's stubbornest
insulation problems.
Unusual air dielectric test is only one of the host of rigorous
tests continually carried out by National to give industry
better insulating materials.
Moisture resistant and dimensionally stable
PHENOLITE epoxy resin and glass base laminate
G -10 -865 meets MIL -P -18177 Specification for
critical electrical and electronic applications.
Flame retardant PHENOLITE Y -2500, used for arc
chutes, tap changer switches, switchgear insulating
barriers and supporting members, refuses to burn -
has excellent arc resistance.
Low cold flow is the outstanding property of
PHENOLITE E -2040 for radio and TV parts. Other
features are low moisture absorption, good dielectric
strength, and ease of hot punching and shearing.
If you have an electrical insulating problem -for
power or electronic applications -bring it to National.
Our staff of Applications Engineers will
help you find the right answer in one of the many
grades of versatile PHENOLITE. If you want more
details of these three new PHENOLITE grades, write
for technical bulletins. Address Department F-6.
