Our FR4 G11 Fiberglass Reinforced Epoxy Resin Rod is a high-performance material designed for demanding applications. With excellent mechanical properties, you can rely on its outstanding bending strength of 241 MPa and tensile strength of 196 MPa. This product offers remarkable resistance to water absorption, with a maximum absorption rate of 0.5% at 13 mm.
The rod's impressive insulation resistance (1.0×10^10 Ω under normal conditions and 1.0×10^7 Ω when impregnated in water) ensures robust performance in various environments. You can count on the breakdown voltage of 15 kV at 90±2°C for reliable electrical insulation, even in transformer oil.
Additionally, the FR4 G11 is classified as FV0 for its flammability rating, offering enhanced safety. Its density falls between 1.70 and 1.79 g/cm³, giving it an optimal balance of strength and weight. Choose our FR4 G11 for a durable, versatile, and highly reliable solution for your next project.

Mechanical Strength:
The material exhibits superior mechanical characteristics, with high tensile, flexural, and compressive strength, enabling it to withstand high load stress. This high strength-to-weight ratio makes it an ideal choice for lightweight structural components.
Electrical Insulation:
The epoxy resin matrix provides the material with excellent electrical insulation properties. Its high dielectric strength and volume resistivity effectively prevent electrical breakdown and current leakage. Furthermore, its insulation performance remains at a high level in humid environments.
Thermal Stability:
With a thermal resistance rating of up to Class B (130°C) and Class H (180°C), the material can operate reliably at elevated temperatures over extended periods without significant degradation of its mechanical or electrical properties due to thermal stress.
Durability and Flammability:
The rods exhibit outstanding resistance to chemical corrosion and aging. Specific grades, such as FR4, possess self-extinguishing flame-retardant properties that meet the FV0 fire-resistance standard, thereby enhancing application safety.
1. Electrical Industry:
You can use our rods as insulating supports, bushings, or structural braces in high-voltage switchgear, transformers, and circuit breakers. Their high dielectric strength and mechanical durability make them perfect for these critical applications.
2. Mechanical Engineering:
Their high strength makes them ideal for manufacturing bearings, gears, and wear-resistant parts in automated machinery where reliability and durability are essential.
3. Aerospace and Transportation:
You can take advantage of their lightweight yet strong properties for structural components in aircraft or for insulating parts in rail and mass transit systems.
4. Electronics:
The FR4 grade, in particular, is widely used for creating insulating spacers and support frames within electronic devices and equipment, where its flame-retardant properties are critical for safety.
