What types of high-pressure laminates and industrial thermosets are available?

The page lists various laminates and industrial thermosets, including Phenolics (Paper, Canvas, Linen base), Epoxy, G-10, FR-4, FR-5, GPO, Melamine, and Silicone. Specific grades like Paper Base (X, XX, XXX, XP), Canvas Base (C, CE), and Linen Base (L, LE) are detailed for their unique characteristics.

What are the key properties and applications for different laminate grades?

Paper Base laminates offer excellent electrical properties with fair mechanical strength, making them suitable for template material or backup stock. Canvas Base laminates, known for their mechanical properties, contain a medium weave fabric. Linen Base laminates also provide strong mechanical properties, with a finer weave allowing for more intricate machining details.

Can these laminate materials be certified to industry standards?

Yes, certain laminate grades can be certified to industry standards. For instance, Paper Base laminates can certify to NEMA XX and MIL-I-24768/10 or 11. Canvas Base laminates can certify to NEMA C/CE and MIL-I-24768/14 or 16.

In what forms are these high-pressure laminate materials available?

These high-pressure laminate materials, including phenolics, are available in various forms to suit different manufacturing needs. The page specifically mentions their availability as sheets and rods.

Laminates and Industrial Thermosets (AKA: Phenolics)

Quick Answer

High Pressure Phenolic Laminates and Industrial Thermosets are a category of synthetic thermoset plastic materials, originally invented by Dr. Leo Baekeland in 1907 and first known as Bakelite. These materials are typically composed of layers of base materials like paper, cotton cloth, or glass fabric impregnated with resin binders such as phenolic or epoxy, offering high temperature resistance and varying mechanical and electrical strengths. Common grades include Paper Base (X, XX, XXX, XP), Canvas Base (C, CE), Linen Base (L, LE), and G-10/FR4, which are widely used in applications like electrical components and mechanical parts.

Thermosets (Paper, Canvas, Linen), Epoxy, G-10, FR-4, FR-5 , GPO, Melamine, Silicone and more

These materials were originally invented by Dr. Leo Baekeland in 1907. First called Bakelite, it is claimed to be the first synthetic thermoset plastic material. Several other base and resin materials are also available; Polyester, Melamine, Nylon and more.

This high temperature resistant material has been used in numerous applications for over 100 years. Other laminate trade names: Phenolic, Micarta®, Phenolfab®, Phenolkraft®, Ryertex®, Garolite®, Spauldite® and Texolite®.

Canvas, Paper and Linen based Phenolic sheet

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 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
