Acculam™ Thermoset Plastic Laminate. Acculam™ is 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, cotton 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. Acculam™ standard stock grades
include:

Acculam™ Epoxyglas G10/FR4 Glass Reinforced Epoxy -
natural (yellowish to light green)
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
Acculam™ EpoxyglasHT G11/FR5 Glass Reinforced Epoxy - natural (yellow
green to amber)
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
Acculam™ Melaglas G5/G9 Glass Reinforced Melamine - natural (grayish
brown)
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
Acculam™ Siliglas G7 Glass Reinforced Silicone - natural (cream
to white)
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

Acculam™ Phenolkraft Paper X/XX/XXX Paper Reinforced
Phenolic - natural (tan)
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
Acculam™ Phenolfab Canvas C/CE Cotton Fabric Reinforced Phenolic -
natural (light tan to brown)
This grade is composed of a continuous cotton 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
Acculam™ Phenolfab Linen L/LE Cotton Fabric Reinforced Phenolic -
natural (light tan to brown)
This grade is composed of a continuous cotton 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.
Certifies to Mil-I-24768/13 FBE
Acculam™ Polymat 1 & 3 Mat Glass Reinforced Polyester - GPO-1 (tan)
and GPO-3 (red)
These grades are composed of random mat (non-woven) fiberglass reinforcement
held together by a polyester resin binder. GPO-3 offers superior arc and
track resistance.
