G5/G9
G5/G9 Glass Melamine Grades are ideal for applications that require high electrical insulation, excellent mechanical strength, and superior heat resistance. Composed of a glass cloth base impregnated with melamine resin, these grades offer exceptional dielectric properties and low moisture absorption, making them particularly suitable for high-temperature and high-voltage environments. Their strong, durable structure ensures reliable performance, making G5/G9 grades a preferred choice for demanding applications requiring effective insulation, stability, and durability.
Material Characteristics and Performance
G5 and G9 laminates share a similar construction but differ in their performance under heat and electrical stress. G5 offers strong mechanical properties, reliable insulation, and moderate heat resistance, making it suitable for structural supports and electrical components. G9 provides enhanced arc resistance and improved thermal endurance, allowing it to perform well in high voltage equipment, power distribution systems, and assemblies exposed to elevated temperatures.
Current, Inc. offers G5/G9 in standard sheet sizes of 36″ × 48″ and 48″ × 96″, with thicknesses ranging from 0.015″ to 3.000″. Tubing is available with inside diameters from 0.375″ to 4.000″ and outside diameters from 0.437″ to 5.000″. Sanded surfaces can be provided to support bonding, machining, or secondary finishing operations.
Fabrication Support for Industrial Applications
G5 and G9 are commonly machined into insulators, spacers, terminal boards, structural supports, and electrical components. Current, Inc. provides routing, drilling, turning, and shaping services to deliver parts that meet precise dimensional requirements. Our fabrication capabilities support prototype quantities, low volume runs, and production scale orders, ensuring consistent tolerances and repeatable performance across multiple builds.
Applications Across Multiple Industries
G5/G9 laminates are used in switchgear, transformers, industrial control systems, power distribution equipment, and high temperature electrical assemblies. Their combination of strength, insulation stability, and arc resistance makes them suitable for environments where materials must maintain performance under electrical and thermal stress.
