Bakelite sheet Grades Available:
Paper Base Laminates;
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.
Canvas Base Laminates;
This 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.
Linen Base Laminates;
This 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.
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.
Bakelite sheets 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 laminate trade names: Phenolic, Micarta, Phenolfab, Phenolkraft, Ryertex, Garolite, Ryertex, Spauldite and Texolite. Please call with additional questions or specification assistance.
FAQ
