Steklotextolite is a material with a multi-layer fiberglass base. This base is made by gluing individual layers of fiberglass by hot pressing. The following compounds are used as binding components in the production of laminated plastic: organosilicon compounds, phenol-formaldehyde resins, polyorganosiloxanes. Depending on the thickness and size of the sheet, the mass of fiberglass varies in the range of 2.0-140 kg.
The main advantage of laminated plastic in comparison with its analogues is its high dielectric strength. This property allows you to use it as a protection of the constructed structure from the action of high voltage current.
Having its physical and technical indicators, the material is widely used in conditions of exposure to an aggressive environment, as well as in places with a high temperature regime. This is due to the fact that it is able to withstand temperature changes in the range from -40 to 105°. Also, as advantages that have increased the industrial value of fiberglass, it is possible to single out such indicators as high strength, heat resistance, elasticity and wear resistance. In addition, plastic is very easy to work with.
