What are High Pressure Phenolic Laminates?

High Pressure Phenolic Laminates are industrial thermoset materials known for their durability, heat resistance, and electrical insulation properties. They are created by impregnating layers of materials like canvas, linen, or paper with phenolic resin and then compressing them under high heat and pressure.

What types of High Pressure Phenolic Laminates do you supply?

We supply a range of high-pressure phenolic laminates, including canvas-based, linen-based, and paper-based varieties. These materials are available to meet diverse industrial requirements for strength, insulation, and wear resistance.

In what forms are these phenolic laminates available?

Our high-pressure phenolic laminates, such as the canvas, linen, and paper-based types, are typically available in both sheet and rod forms. This provides flexibility for various manufacturing and application needs across different industries.

What are common applications for canvas, linen, and paper-based phenolic laminates?

Canvas-based laminates are often used for mechanical applications like gears, while linen-based are preferred for finer machining and electrical insulation. Paper-based laminates are commonly utilized for electrical components and general-purpose insulation due to their specific properties.

High Pressure Phenolic Laminates: Canvas, Linen & Paper Based

Quick Answer

High-pressure phenolic laminates, originally invented by Dr. Leo Baekeland in 1907 as Bakelite, are industrial thermoset plastic materials valued for their high temperature resistance and diverse mechanical and electrical properties. These laminates are categorized by their base materials, such as paper, canvas, or linen impregnated with phenolic resin, or glass woven fabric with epoxy resin for G-10/FR4 grades. Specific types like G-10/FR4 offer extremely high mechanical strength and good dielectric loss properties, making them suitable for a century of applications including circuit boards, relays, and motor housings.

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
