Black bakelized paper LBNN
Bakelite is a composite material based on thermohydrogenated phenolic resin obtained from formaldehyde and phenol for electrophilic substitution; Bachilite paper is the result of the cellulose paper stratification with and the phenolic resin compound.
Born in 1907, it is the first thermosetting material, that is, a material that, when melted, cooled and hardened, can no longer be heated or remodeled.
In the field of industry it has brought a great innovation, because of its features and the low costs it has had a great diffusion up to the 50 years later replaced slowly by the new plastic materials.
Bakelite has thermal-insulating properties that, in the past, have largely been used in electro-electric elements, electrical switches, electric sockets, cookware handles, radiosets, and others. It is considered the first synthetic plastic material produced and used, although preceded by natural-based plastics, black version
- Good dielectric characteristics even in humid environments
- Excellent friability even in cold weather.
- Very good heat resistance.
- Resists industrial solvents
- Discrete mechanical properties improved in cotton fabric version
- Despite the good thermal insulation properties it is not suitable for working in high temperature environments.
- During processing, it creates dust.
- Sunlight and time can darken the color.
- It does not resist acids
The most important uses are in the mechanical and electrical sector. Applied to low-voltage apparatus, electric boards and supports. Ideal for making gears, bushings, cams, silent gears
