What is Phenolic Material?

Phenolic is a fabricated reinforced laminate produced from a fine weave Linen/Cotton cloth impregnated with a phenolic resin binder. The fine weave phenolic linen yields good mechanical properties, dimensional stability and a better finish for machined components than the CE material, particularly for intricate detailed components. However, it is not recommended for electrical primary insulation! Other benefits include high tensile, compressive and flexural strength, good resistance and strong electrical properties. LE phenolic meets Mil-I-24768/13 FBE requirements. It is available in sheet stock, rod, angle and U channel forms.

While LE phenolic material is hard and dense, it is also relatively light – LE phenolic sheets are about half the weight of aluminum sheeting. Despite its lightness, the material features a high strength-to-weight ratio. The material’s moisture rate is 1.3 percent and it can withstand temperatures of up to 285°F. LE phenolic machining is also a relatively clean and easy process that is amenable to customization.

LE Phenolic is available in:

  • Sheet Material – 36 in. x 48 in. sheets

no minimum order requirement

CE Phenolics

CE phenolic is a fabricated reinforced laminate produced from a medium weave cotton cloth impregnated with a phenolic resin binder. The medium weave canvas yields good mechanical properties. However, it is not recommended for electrical primary insulation applications. CE phenolic meets Mil-I-24768/14 FBG requirements. It is available in sheet stock, rod, angle and U channel forms.

This cotton-canvas type material is frequently used in the manufacturing of pulleys, rollers, gears and guides. It also serves as electrical insulation in control boards. In addition to its good mechanical properties and toughness, CE phenolic offers high impact strength and exhibits good wear resistance; it is less abrasive than fiberglass when used in wear resistance applications. As with LE phenolic, this material can withstand temperatures of up to 285°F. CE phenolic machining is also a fairly easy procedure.

XX Phenolics (NEMA)

NEMA (National Electrical Manufacturers Association) designated laminates are unclad materials comprised of different resin systems, some incorporating woven glass weave, non-woven and some none at all. Each laminate exhibits unique electrical, mechanical and chemical performance characteristics and have specific uses based on these criteria. These laminates can be fabricated into components a variety of uses in the Aerospace, Automotive, Electronic, Industrial and Petroleum Industries. Lighter than metal but dense and strong, this paper-based material absorbs less moisture than impact resistant CE Garolite. Sometimes called paper-grade industrial laminate, phenolic, or Bakelite, it is often used for gasketing and gears. All meet MIL-I-24768/11. Available in sheets, strips, and rods also meet UL 94HB for flame retardance.

This phenolic material has the ability to fend off corrosion and is resistant to friction, abrasion, metal fatigue and many types of chemicals. NEMA XX can withstand temperatures of up to 257°F and features an impact strength of ASTM D732): .055 ft. lb/in. of notch. As with LE and CE phenolic, NEMA XX machining can be executed quickly and easily.

  • XPC = Paper Phenolic Resin – Mechanical Grade – Cold Punch-able Grade
  • XX = Paper Phenolic – General Purpose Grade
  • XXP = Paper Phenolic Resin – Mechanical Grade – Hot Punch-able
  • XXX = Paper Phenolic Resin – Electrical Grade

We Offer a Wide Variety of Phenolic Machining Services

At American Micro Industries, phenolics machining is one of our many areas of specialized expertise. We can provide custom precision CNC machined LE, CE and XX phenolic components that meet your specifications. In addition, we can produce custom Garolite® (fiberglass) parts that are a popular choice for many electrical insulation applications.

We offer turnkey CNC machining solutions that can provide customized results for each project. Our phenolic machining process begins by using your mechanical drawings to establish project parameters and determine the most suitable CNC machining technique. We can also develop a custom prototype prior to implementing a mass production process to ensure your part or component will meet your performance expectations. Our capable CNC staff will work closely with you to engineer and fabricate your custom parts and provide the turnkey solution you need to meet your quality and production goals.

We have a fully equipped machine shopping featuring CNC machinery and tooling. We also have a large CNC machining capacity that enables us to handle the biggest LE, CE and Nema XX machining jobs with ease. What’s more, we can perform various secondary machining procedures to provide the perfect finishing touch for your parts and components.
