introduction
Temperature-resistant insulation bakelite sheet — natural color is typically orange or black. known as Phenolic paper laminated owns the character of good mechanical strength, anti-static, intermediate electrical insulation. It`s made by insulating bakelite impregnated with phenolic resin, after baking hot pressing. This product is suitable for high performance requirements of electrical machinery, electrical equipment as insulating structural parts, and in the transformer oil. Room temperature electrical properties with good machining performance, the proportion is 1.45, warpage 3 ‰ maximum, with excellent electrical, mechanical and processing properties.
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.
