What Is Paper Bakelite?
Paper Bakelites are a type of Bakelite made by mixing phenol resin with paper as a base material.
In addition to Paper Bakelites, there are other types of Bakelites such as Cloth Bakelites that use cloth as a base material, and they are used in different ways depending on the situation. Paper Bakelites are strong, inexpensive, and have excellent electrical insulation properties. It is also easy to process, such as cutting and polishing, and can be used to make parts in a variety of shapes.
Uses of Paper Bakelites
Bakelite materials, including Paper Bakelites, are often used for electrical insulation because of their high strength and exceptional electrical insulation properties.
It is generally used inside equipment such as switchboards, but it is also used for electrical switches and knobs that control the volume of sound. Since these are places that people touch, Paper Bakelites are used for their high electrical insulation and easy shapeability to prevent electric shock.
Other Information on Paper Bakelites
1. Characteristics of Paper Bakelites
Paper Bakelites are a type of Bakelite. Bakelites are called laminates and are composed of phenolic resin and a base material. Paper Bakelites are distinguished by the term Paper Bakelites when the base material is paper and Cloth Bakelites when the base material is cloth.
Since these Bakelites are laminated plates, the surfaces perpendicular to the layers have considerably high mechanical strength, but the surfaces parallel to the layers are prone to delamination and have low strength.
When processing, it is necessary to check the direction in which force is likely to be applied while processing so that strength is maintained.
2. Manufacturing Method of Paper Bakelites
Paper Bakelites are manufactured by synthesizing phenol and formaldehyde to create phenolic resin. Since this alone lacks strength, paper, which serves as a reinforcing agent, is laminated in sequence and heated and pressed. Since paper is laminated between the layers, the paper part easily absorbs moisture and is not suitable for use in wet areas.
