Overview
Tracking-resistant epoxy glass laminates are selected for electrical insulation where contamination, humidity, surface leakage or high-voltage switching conditions create a risk of tracking. They are distinct from standard FR4 or G10 because the resin system and validated tracking performance are grade-specific. MaterialCut confirms the relevant standard, thickness and end use before quotation.
