What are the primary differences between paper, canvas, and linen base phenolic laminates?

Paper base laminates (X, XX, XXX, XP) offer excellent electrical properties with fair mechanical strength, suitable for uses like template material. Canvas base (C, CE) provides strong mechanical properties, while linen base (L, LE) also offers mechanical properties with a finer weave for machining intricate details. Each grade certifies to specific NEMA and MIL-I standards.

In what forms are high-pressure phenolic laminates typically available?

High-pressure phenolic laminates, including canvas, linen, and paper base phenolics, are commonly available in sheet and rod forms. The meta description and site navigation indicate availability in these forms to support various industrial applications.

Can I get assistance with material selection or specific application requirements for phenolic laminates?

Yes, the page explicitly invites users to call for additional questions or specification assistance. This service helps ensure the correct phenolic laminate is chosen for specific project needs, aligning with the business's focus on engineering plastic solutions.

What are some typical uses or applications for high-pressure phenolic laminates?

These high-temperature resistant materials have been used in numerous applications for over a century. Depending on the grade, they are suitable for uses such as template material, backup stock, or machining intricate details like small gear teeth, leveraging their specific mechanical and electrical properties.

High Pressure Phenolic Laminates: Canvas, Linen & Paper Based

Quick Answer

High Pressure Phenolic Laminates and Industrial Thermosets are a category of high-temperature resistant materials, originally invented by Dr. Leo Baekeland in 1907 as Bakelite. These materials consist of layers of base materials like paper, cotton cloth, or glass woven fabric, impregnated with resin binders such as phenolic or epoxy, offering excellent mechanical strength and electrical properties. Industrial Plastic Supply provides various grades, including Paper Base (NEMA XX), Canvas Base (NEMA C/CE), Linen Base (NEMA L/LE), and G-10/FR4 (NEMA FR4). They are widely applied in components like relays, switches, and circuit boards due to their durability and resistance.

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
