Product Description
FR4 / G10 Fiberglass Rod – High-Strength Electrical Insulation & Structural Composite
Manufactured by Youda Insulation Materials Co., Ltd.
Precision Engineered | Customizable | Global Export Ready
Product Introduction
The FR4 and G10 fiberglass rods are high-performance thermoset composite materials made from woven E-glass fabric impregnated with epoxy resin. These rods deliver exceptional mechanical strength, dimensional stability, and outstanding electrical insulation—making them ideal for demanding applications in electrical engineering, automation, aerospace, semiconductor fixtures, and industrial machinery.
· FR4: Flame-retardant (UL94 V-0), preferred for safety-critical electrical components.
· G10: Slightly higher mechanical strength, ideal for structural parts where fire rating is not required.
Both materials are non-conductive, non-magnetic, chemically resistant, and maintain performance across extreme temperatures.
· G10: Slightly higher mechanical strength, ideal for structural parts where fire rating is not required.

Company Introduction
FAQ
Q1: What's the difference between FR4 and G10 rods?
A: Both offer similar mechanical and electrical properties. The key difference is that FR4 is flame-retardant (UL94 V-0), while G10 is not. G10 typically has slightly higher flexural and tensile strength. Choose FR4 for electrical safety compliance; choose G10 for pure structural performance.

Q2: Can I machine FR4/G10 rods myself?
A: Yes! They are highly machinable using standard metalworking tools (carbide-tipped recommended). Use dust extraction during cutting/grinding—fine glass particles require proper ventilation.

Q8: Are FR4/G10 rods suitable for outdoor use?
A: They perform well in humid environments due to very low moisture absorption (<0.15%). However, prolonged UV exposure may cause surface discoloration—consider protective coating if used outdoors long-term.
