Bakelite continues to be used for wire insulation, brake pads and related automotive components, and industrial electrical-related applications. Bakelite stock is still manufactured and produced in sheet, rod, and tube form for industrial applications in the electronics, power generation, and aerospace industries, and under a variety of ...
Uses Bakelite: Phenol-formaldehyde resin: High electric, heat and chemical resistance: Insulation of wires, manufacturing sockets, electrical devices, brake pads, etc. Kevlar: Para-aramid fibre: High tensile strength: Manufacturing armour, sports and musical equipment. Used in the field of cryogenics: Twaron: Para-aramid: Heat resistant and ...
Phenol-formaldehyde resins, as a group, are formed by a step-growth polymerization reaction that can be either acid- or base-catalysed.Since formaldehyde exists predominantly in solution as a dynamic equilibrium of methylene glycol oligomers, the concentration of the reactive form of formaldehyde depends on temperature and pH.

G-10 is used to reinforce the edges of fiberglass coated wood. It is used to protect the point-of-contact on many such items. During ordinary use it is the G-10 that takes the brunt of the blow. In such applications it is meant to be replaced as it wears. G-10 is also used as a 3D-Printer build surface.
The National Electrical Manufacturers Association (NEMA) defines standards used in North America for various grades of electrical enclosures typically used in industrial applications. Each is rated to protect against personal access to hazardous parts, and additional type-dependent designated environmental conditions.
Pressboard, a board made by compressing layers of paper together and drying them, has been used for installation purposes in many of the first electrical machines. However, as electrical technology increased, the need for a higher density material that was capable of insulating larger and higher voltage transformers grew.
Bakelite, a phenol-formaldehyde resin used in electrical insulators and plasticware. Duroplast, light but strong material, similar to Bakelite formerly used in the manufacture of the Trabant automobile, currently used for household objects; Urea-formaldehyde foam used in plywood, particleboard and medium-density fibreboard.
