Micarta is an early composite insulating plate that used Bakelite as a binding agent. It was developed in 1910 by the Westinghouse Electric & Manufacturing Company, which put the new material to use for casting synthetic blades for Westinghouse electric fans. [81] Novotext is a brand name for cotton textile-phenolic resin. [82]
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 ...
The base material choice depends on the intended application of the finished product. Paper phenolics are used in manufacturing electrical components such as punch-through boards, in household laminates, and in paper composite panels. Glass phenolics are particularly well suited for use in the high speed bearing market. Phenolic micro-balloons ...
Various magnesia cement boards are used in Asia as a primary construction material. Some versions have been designated as the official construction-specified material of the 2008 Summer Olympics , and some versions are used extensively on the inside and outside of all the walls, fireproofing beams, and as the sub-floor sheathing in one of the ...
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.
This thermoset polymer type is merged into composites as a prepreg matrix used in electrical printed circuit boards, and for large scale structural aircraft – aerospace composite structures, etc. It is also used as a coating material and as the matrix of glass reinforced pipes, particularly in high temperature and chemical environments.

It was originally used in electrical and decorative applications. Micarta was developed by George Westinghouse at least as early as 1910 using phenolic resins invented by Leo Baekeland . These resins were used to impregnate paper and cotton fabric which were cured under pressure and high temperature to produce laminates.
