Laminates, G-10, Paper, Linen, Canvas Phenolics For Dummies. AKA, For The Beginner*

Why use laminates:

  • They all have Very High Electrical Properties
  • Laminates Are Very Stiff and Rigid Materials
  • Are Machinable Material with Excellent Mechanical Properties
  • Great for flat Table Top, Electrical Insulators and Mechanical Parts

Laminates, G-10, FR-4, Paper, Linen, Canvas Phenolics For Experts

*This materials is…

an excellent insulation material – used in mechanical and wear parts.

  • Excellent Electrical Insulation Properties
  • Very stiff with exceptional dimensional stability
  • Several grades depending on your demanding application

Grades Available:

Paper Base Laminates;

(X, XX, XXX, XP) – Composed of layers of paper base impregnated with a phenolic resin binder. It has excellent electrical properties with fair mechanical strength. Outstanding for use as a template material or backup stock material. It can certify to NEMA XX (in XX Grade), and MIL-I-24768/10 or 11

Canvas Base Laminates;

(C and CE) – This grade is composed of a continuous cotton woven cloth impregnated with a phenolic resin binder. This grade contains a medium weave canvas fabric and is known primarily for it’s mechanical properties. Not recommended for primary insulation. It can certify to NEMA C/CE, and MIL-I-24768/14 or 16

Linen Base Laminates;

(L and LE) – 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 canvas phenolic, is known for it’s mechanical properties. The finer weave allows for machining more intricate details than the Canvas, ie: small gear teeth. It can certify to NEMA L/LE, and MIL-I-24768/13 or 15

G-10 / FR4 Laminates;

(G-10 and G-10 FR4) – The most versatile all-around laminate, this grade is comprised of layers of a continuous glass woven fabric base impregnated with an epoxy resin binder. It has extremely high mechanical strength, good dielectric loss properties, both wet and dry. Extremely abrasive while machining, diamond tooling is recommended.  It can certify to NEMA FR4, and MIL-I-24768/27

These materials were invented by Dr. Leo Baekeland in 1907, and is claimed to be the first synthetic thermoset plastic material, and was first called Bakelite. Several other base and resin materials are also available; Polyester, Melamine, Nylon and more. A high temperature resistant material used in numerous applications for over 100 years. Other trade names: Phenolic, Micarta, Phenolfab, Phenolkraft, Ryertex, Garolite, Spauldite and Texolite. Please call with additional questions or specification assistance.
