Glass-Melamine Laminate Characteristics

Melamines are the hardest of the laminates with good dimensional stability and arc resistance.

G5 and G9 are machining-grade glass fabrics that retain excellent electrical properties in high humidity conditions. Both thermosets are flame-resistant and have high physical strength, good caustic-resistance and excellent arc resistance.

G9 is a better choice for outdoor applications as it offers more resistance to the elements than G5.
