Phenolic Thermoset Plastic Laminate.
Phenolics are a uniformly dense and structurally strong material that will
not soften appreciably under the reapplication of heat. It is an extremely
durable plastic that is lightweight and moisture resistant. Industrial
laminates are thermoset resin impregnated reinforcing materials (paper,
fabric, glass fabric, etc.) that are cured under heat and pressure to form
solid shapes having high mechanical and electrical insulating properties.
Laminates are available in sheet, rod, tube, and angle. Since laminates
are comprised of a combination of materials, they are also referred to as
composites. Phenolic standard stock grades include:
|
G10/FR4 Glass Reinforced
Epoxy - natural (yellowish to light
green)
Technical Data Sheet
The most versatile all-around laminate, this grade is a continuous glass
woven fabric base impregnated with an epoxy resin binder. It has extremely
high mechanical strength, good dielectric loss properties, and good
electric strength properties, both wet and dry.
Certifies to Mil-I-24768/27 GEE-F
G11 Glass Reinforced Epoxy - natural
(yellow green to amber)
Technical Data Sheet
This grade is similar to G10/FR4, with the addition of a higher operating
temperature and some improved mechanical strength at elevated
temperatures.
Certifies to Mil- I-24768/28 GEB-F
G5/G9 Glass Reinforced Melamine - natural
(grayish brown)
Technical Data Sheet
This grade is composed of a continuous glass woven cloth base impregnated
with a melamine resin binder. Melamines are the hardest of all laminates,
exhibiting good dimensional stability and arc resistance. It is also
caustic resistant.
Certifies to Mil-I-24768/1 GME
G7 Glass Reinforced Silicone - natural
(cream to white)
Technical Data Sheet
Composed of a continuous glass woven cloth base impregnated with a
silicone resin binder,this grade has excellent heat and arc resistance. It
has extremely good dielectric loss properties under dry conditions and
good electrical properties under humid conditions, although the percentage
of change is high.
Certifies to Mil-I-24768/17 GSG

Paper X/XX/XXX Paper
Reinforced Phenolic - natural (tan)
Technical Data Sheet
This grade is composed of a paper base impregnated with a phenolic resin
binder. It has good electric strength properties with fair mechanical
strength. Outstanding for use as template material and or backup material.
Certifies to Mil-I-24768/12 PBM, /11 PBG and /10 PBE
Canvas C/CE Cotton Fabric Reinforced Phenolic
- natural (light tan to brown)
Technical Data Sheet
This grade is composed of a continuous woven cloth impregnated with a
phenolic resin binder. This grade contains a medium weave canvas and is
known primarily for it's mechanical properties. This grade is not
recommended for primary insulation.
Certifies to Mil-I-24768/14 FBG
Linen L/LE Cotton Fabric
Reinforced Phenolic - natural (light
tan to brown)
Technical Data Sheet
This grade is composed of a continuous woven cloth impregnated with a
phenolic resin binder. This grade contains a fine weave linen and, like
the canvas phenolic, is known for it's mechanical properties. The finer
weave allows for machining more intricate details than Canvas, like gear
teeth. This grade is not recommended for primary insulation.
