Electrical insulation

Our wide range of products for electrical engineering includes: fluoroplastic films, solid Novolak resins, varnish type Novolak resin solutions, varnish type resol resin solutions, blending of novolak resins with resol or epoxy resins.

A variety of films with thickness of 0.005-0.2 mm and tapes with thickness of 0.2-3.0 mm made with  PTFE-4 (polytrifluorochloroethylene). Films are peeled from sintered extruded PTFE blocks. Depending on the purpose, films can be additionally oriented (by rolling and stretching). Film width can be 10-120 mm as required by the customer. Physico-mechanical and dielectric properties of films are controlled.

Phenolic resins provide high mechanical strength and electrical insulation properties of electrotechnical sheet materials. Novolak resins are used as binders for making phenoplast compositions. Modified Novolak resins facilitate the processing of phenoplast molding compositions,  increase electrical insulation properties and chemical resistance.

Phenolic resins provide high mechanical strength and electrical insulation properties of electrotechnical sheet materials. Varnish resins composed of the phenolic resin solution in various alcohols are used for electrical insulation. Phenol-formaldehyde varnishes are widely used to impregnate and coat natural and synthetic fibrous materials. Elasticity of resol-resin-based coatings is higher than that of coatings based on pure Novolak resins. The best effects can be achieved by using the both types of phenol-formaldehyde resins.

Uralchimplast produces both pure resol varnishes and mixed varnishes composed both of resol and Novolak resins.
