25045 — Gost

Acting as a heat-resistant electrical insulator in industrial furnaces. Why It Matters Today

According to archival technical documentation found on Calaméo , this standard governs the production and quality control of insulating sheets and tapes made by bonding thin flakes of natural mica together using various resins or varnishes. Key Components of the Standard gost 25045

The maximum operating temperature (ranging from Class B at to Class H at or silicone) that can be used.

Resistance to bending, compression, and shearing. Industrial Applications gost 25045

GOST 25045-81 is a critical technical standard originating from the Soviet/Russian regulatory framework that specifies the requirements for , commonly referred to as micanite. These materials are vital in high-voltage engineering due to mica's exceptional thermal stability and dielectric properties. What is GOST 25045?

Minimum voltage thresholds the material must withstand before failing.

It defines the types of mica (such as muscovite or phlogopite) and the binding agents (shellac, epoxy, or silicone) that can be used.
