Epoxy Board IP‑6800BQ
Product Overview
TONMAX IP‑6800BQ epoxy board (FR4 G‑10 grade) is epoxide woven glass fabric laminated sheet. It is manufactured by impregnating electronic‑grade woven glass‑fiber cloth with epoxy resin system, followed by high‑temperature hot‑press lamination. It complies with IPC‑4101B specification, featuring high glass‑transition temperature, excellent mechanical strength, stable dielectric performance and UL94 V‑0 flame‑retardant rating. This high‑performance laminate serves as structural insulating parts for mechanical, electrical and electronic equipment.
Main Applications
• High‑voltage insulating structural components for electrical cabinets, transformers and switch‑gear assemblies
• Insulating spacer, support plate and fixture for new‑energy battery & power electronic equipment
• Precision machined mechanical‑electrical parts for industrial automation devices
• Base substrate and insulating barrier for electronic modules and testing equipment
Core Advantages
✅ High mechanical performance: superior flexural, tensile and impact strength, low bow‑twist deformation
✅ Reliable electrical insulation: stable surface & volume resistivity, high dielectric strength and arc resistance even under humid conditioning
✅ UL94 V‑0 flame‑retardant grade, high glass‑transition temperature (Tg≥130℃), excellent thermal stability
✅ Low moisture absorption, consistent dielectric property after humidity conditioning
✅ Good machinability, supports CNC cutting, drilling, punching for custom‑shape components
✅ Compliant with IPC‑4101B industry specification for electrical laminate materials
Storage Note: Store indoors under cool, dry condition. Avoid direct sunlight, high‑humidity environment and heavy mechanical impact.
