Description

Acid - resistant paronite (PC) is produced in the form of sheets in accordance with the requirements of GOST 481 - 80. The main area of application of paronite sheet is the manufacture of sealing gaskets for flat detachable joints of various components and assemblies. The gaskets can be cut from a solid paronite sheet, or they can be composite. In the manufacture of composite gaskets, individual parts are fastened together using glue ("overlap" or "dovetail"). Acid - resistant paronite can also be used as a soft filler in spiral - wound cushioning materials.

 


Paronite is acid - resistant and gaskets made of it can be used in any climatic conditions (in temperate, cold and tropical climates). Paronite PC in areas with a tropical climate can be used without adding fungicides. The minimum working temperature of paronite is minus 60 ° C.
