The main part of the insulating resin insulating material which provides the main electrical, mechanical and thermal properties of the insulating material.

Epoxy Resin

Where the molecular structure of the polymer compound containing Epoxy groups, collectively referred to as an Epoxy resin, generally colorless or pale yellow, liquid or solid. Epoxy resin has excellent adhesion strength, good dielectric properties, low shrinkage, good electrical performance stability, high hardness, flexibility, good stability to alkali and most solvents, which are widely used in various sectors for laminating materials, adhesives, coatings and other uses. The field of power generation, transmission and distribution of electricity are required to produce epoxy insulating material.

Phenolic resin

Phenol and formaldehyde under acidic or alkaline catalyst, by polycondensation reaction of polymer resin, commonly known as phenolic resin. Appearance may be colorless and transparent, yellow or brown as a solvent is generally without a solid state. Different phenol, aldehyde, catalyst. Different molar ratio of phenol and formaldehyde to produce a variety of phenolic resin, comprising: a thermoplastic novolak resin, a thermosetting phenolic resin; soluble phenol resins, water-soluble phenolic resin. A large number of phenolic resin used to manufacture insulation materials, plywood, molding etc.; insulation materials industry is mainly used for the production of plastics and pressure laminated products, insulating paint, etc..

Polyester resin

The polyester resin is a dicarboxylic acid (or dimethyl ether) and the polyhydric alcohol, after direct esterification (PTA method) and an ester exchange method (DMT method) polymer obtained by the process, typically a thermoplastic resin, a small amount of are thermosetting; uses polyester resin is very wide, in addition to polyester fiber, various types of containers, packaging materials, films, film, engineering and other fields, the extensive use of; up to our daily contact with the various types of beverage bottles and polyester fibers clothing; insulating materials used in the manufacturing industry more electrical polyester film, nonwoven and DMD composite products, as well as wire paint.

Unsaturated polyester resin

Unsaturated polyester resin is a polyhydric alcohol and a polybasic acid (anhydride), polyunsaturated acids (anhydrides) polycondensation polymer compound of the general, and is fundamentally different from a polyester resin, a thermosetting resin, a curing initiator double bonds; can be mixed with vinyl monomers such as styrene, acrylates, vinyl esters such as the acetate, in the role of initiator and accelerator, the polymerization at room temperature into an insoluble, infusible product. Up is our daily contact with all kinds of glass fiber reinforced plastic products, such as boat park, amusement equipment, etc.; insulation material manufacturing industry to use more insulation moldings, panels, Stubbs, non-wai, as well as insulation impregnated with resin.

Alkyd resin

Polyhydric alcohols, phthalic anhydride and a fatty acid or oil (fatty acid triglycerides) condensation polymerization of oil-modified polyester resins, alkyd resins generally known; insulating material is mainly used to make cloth insulation varnish and cloth.
