Welcome to Beeplastic's collection of high-performance FR-4 and G-10 glass epoxy laminates. We provide both standard sheets & rods and expert custom fabrication services. Understanding the core difference between these materials is key to selecting the right solution for your project.

Understanding Our FR-4 and G-10 Materials

Below we detail our two primary phenolic laminate categories. While both offer exceptional strength and insulation, their key distinction lies in flame retardancy, defining their ideal applications.

FR-4: The Choice for Electronics & Fire Safety

FR-4 is the industry standard for applications where flame retardancy is critical. Compliant with the UL 94V-0 standard, this grade is self-extinguishing, making it the mandatory choice for printed circuit boards (PCBs). Its excellent electrical insulation and dimensional stability also make it perfect for high-voltage insulators and electronic enclosures.

G-10: For Unmatched Mechanical Strength

G-10 is prized for its exceptional mechanical strength, toughness, and durability. Made with a non-brominated epoxy resin, it is the ideal material for high-strength structural parts where flame retardancy is not a factor. Its ability to withstand high impact and wear makes it a superior choice for mechanical applications.
