Thermoset Shapes & Fabrication
The Atlas Fibre Company is a North American supplier of thermoset/laminate sheet, rod and tube. They supply the following materials: G-10, G-11, FR4, G-9, G-7, G-5, G-3, and paper, linen and canvas phenolic. All Atlas Fibre materials meet/exceed NEMA and Mil-Spec standards. They can cut to tight tolerances, precision sand materials up to 2.00” thick and fabricate all of these materials.
In addition, for those machine shops that don’t like to machine thermosets/laminates, Atlas Fibre has more than 30 CNC machines on their shop floor including Swiss turning, five-axis routing, five-axis milling and multiple routers for high volume production runs.

Accurate Plastics, Inc.
since 1980 has provided
NEMA LI-1 and MIL-I-
24768 certified Acculam®
thermoset composites in
sheet, tube, rod and other
Thermoset plastics are
unique composites of
cross-linking resins with
reinforcing materials that
are permanently cured by
heat and pressure. Once cured, they become very rigid,
durable and maintain physical properties in hot conditions
better than thermoplastics. This plastic, pioneered
in the early 20th century was known as Bakelite and found
many uses in the electronics industry of the mid-20th century
and spawned development of additional grades during
the industrial revolution. Typically referred to as
Grades G10, G11, G9, G5, G7, G3, FR4, FR5, CE, LE, XX,
today they continue to expand relevance in electronics,
aerospace, gaskets, heavy equipment, medical, magnetics,
energy and other applications.
A new grade, MATRIX HT, provides excellent maintenance
of properties at temperatures up to 500°F and over.
These composites may be combined with other components
such as metals, etc. to develop special properties
that allow flexibility in design of devices. Where high
mechanical strength and resistance to heat or electricity
are necessary, thermoset composites allow designers a
flexible, durable, lightweight option for replacing thermoplastics,
metals and other high weight components.

Polymics Ltd. continues
both thermoset and
Polymics and its
to key industries and they now offers comprehensive composite
processes including filament wound tubes and lining
products, high strength pultruded rods, and a unique
“Pulwinding” processes that combines the benefit of
Pultrusion in tensile strength and filament winding in
hoop strength for structural profile applications. These
processes were designed to meet cost reduction and performance
enhancements in oil/gas, semiconductor/electronics
as well as other industries. Typical resin systems
adopted currently are standard and high temperature
epoxy as well as most unsaturated polyester systems.
In addition, Polymics has initiated a thermoplastic composite
program as an extension of its comprehensive high
heat polymer programs. Initial products include a
Pyramid CC product line with PEEK, PAEK and PPS as the
basic resin matrix. Currently, compression molded products
and limited long fiber composite systems are offered
for medical, aerospace and analytic instrumentation
meeting increased strength requirements while still delivering
weight savings and critical chemical resistance.
Polymics “Concept to Solution” mission addresses each
customer’s individual application requirements when providing
a cost-effective solution that meets all critical performance
criteria. This is accomplished through experience
and expertise that encompasses: material development,
polymer formulation including recently patented
high temperature Polyketones, custom compounding,
part design, polymer conversion, prototype fabrication,
assembly and complete testing in their ISO-9001 certified
Polymics also offers an extensive inventory of thermoplastics
such as PEEK tube where they utilize several
processes including hot compression molding, injection
molding, extrusion and centrifugal molding to supply the
industries most extensive size capabilities.

To meet the military’s growing
requirement for ballistic
Micarta has developed
specialty line of high
composite sheets, pre-pregs,
and molded shapes. This fiber
-glass-based material is resistant to projectiles, ricochet,
heat, and fire, making it suitable for the most threatening
Typically used to arm vehicles and guard stations, the
material provides exceptional structural strength, plus
both ballistic and ricochet resistance against small arms
fire, blasts, and fragmentation. Lighter than steel, it is
easy to handle and machine, allowing for ease of installation

Laminates for PCBs
Current, Inc. manufactures specialized copper clad laminates
or electrical grade laminates that are ideal for printed
circuit boards and insulators. Manufactured in the
U.S., they specialize in custom thickness, coppers and colored
applications for short runs, prototypes and production
Their FR4 copper clad laminates are a fire rated electrical
grade, dielectric fiberglass material created under
high pressure with electro deposited HTE (high-temperature
laminated on to the FR4
substrate. It is commonly
used for printed circuit
Colored FR4 is available
in black, blue and yellow,
as well as natural. Their
black copper clad laminates
and electrical grade laminates are used for PCBs
with light blocking capabilities for LEDs, night vision and
aerospace applications. Colored FR4 is available in a solid
color throughout and a 50% natural and 50% color configuration.
All of Current’s FR4 is manufactured in multi-tetra and
di-functional epoxies. They also manufacture high-temperature
copper clad laminates in FR5 with the same
functionality, but exhibiting better flexible strength at elevated
