While many modern standards have shifted toward synthetic polymers, mica-based materials remain indispensable for "heavy-duty" electrical applications where reliability under extreme heat is non-negotiable. Manufacturers in the CIS region still reference GOST 25045 to ensure compatibility with legacy industrial infrastructure and to maintain a baseline of proven material durability.
