Paronite is a sheet gasket material made by pressing a mass consisting of asbestos, rubber and powdered ingredients. Paronites are supplied in sheets from 0.4 mm to 6 mm thick.

Technology of production of asbestos paronite:

For example, in the production of General-purpose paronite PON, only high-quality natural rubber is used. It is no secret that today domestic producers, with a shortage and high price of natural rubber, use PON, synthetic rubber in the production of paronite. Different properties of paronite are given by the use of different asbestos fibers. High-quality long-fiber chrysotile asbestos of group 3,4, asbestos A-3-60 is used for paronites intended for heavy operating conditions, where the breaking load parameter is one of the key parameters. The operating temperature of this paronite is +350 ° C. For paronites intended for use in less severe conditions, at lower temperatures, for example, with a working temperature of +150 ° C, chrysotile asbestos A-5-65, belonging to the group 5,6, is used.also, the technical parameters of paronite depend on the amount of natural rubber introduced into the mixture. Additionally, the fact that the paronite of various technical parameters is achieved by using the production parnikovoy blend of special additives in the right proportions.

Application:

Paronite is used in the chemical and petrochemical industry, in Metalworking, mechanical engineering and metallurgy, electric power and electrical engineering to seal and ensure the necessary tightness of various types of connections under the influence of aggressive environments, high temperatures and pressure. Our company is a supplier of special cushioning materials with unique properties that are used in environments of concentrated acids and alkalis, oxidizers and refrigerants.

Properties:

This is the most common and universal cushioning material. The yield strength is about 320 MPa. When this pressure level is reached, it begins to flow, as a result of which all loose connections are filled with material and sealed. For the most effective sealing, the thickness of the gasket should be as small as possible, but sufficient to completely fill the grooves and unevenness of the connection. When installing a thicker gasket, it increases the probability of its squeezing out, which can lead to depressurization of the connection.
