How to Recognize Genuine G10 Epoxy Sheet?

Recognizing genuine G10 epoxy sheet requires a combination of visual inspection, physical examination, and performance testing. Authentic G10 exhibits a distinct appearance with a smooth, uniform surface and consistent color throughout. Its high-density structure should feel solid and weigh appropriately for its size. When subjected to stress, genuine G10 demonstrates exceptional strength and rigidity without flexing easily. Electrical insulation properties can be verified through conductivity tests, while chemical resistance can be assessed by exposing a small sample to common solvents. Additionally, authentic G10 maintains its properties under high temperatures and resists moisture absorption. By employing these multifaceted evaluation techniques, one can confidently identify genuine G10 epoxy sheet and ensure its suitability for critical applications in electronics, aerospace, and other demanding industries.
