Our Epoxy Resin Fiberglass Cloth Electrical Insulation Tube is designed to offer superior performance for a wide range of electrical applications. With a density of over 1.4 g/cm³, it ensures reliable strength and durability. You can rely on its exceptional thermal resistance, as it maintains high flexural strength (>160 MPa) and compressive strength (>50 MPa), even under varying conditions.
The tube offers excellent electrical properties, including surface resistance and volume resistivity, with values greater than 1.0x10^10 Ω and 1.0x10^8 Ω·m, respectively, ensuring long-term insulation reliability. Whether under normal conditions or in high humidity, you can trust its performance.
Our product features impressive dielectric strength, with withstand voltages reaching up to 25 kV for dielectric breakdown. It provides optimal insulation resistance (>1.0x10^7 Ω) and low dissipation factor (<0.03) at 50Hz, ensuring minimal energy loss.
With a variety of tube sizes and thicknesses, you can choose the right configuration for your needs. Available in both natural and green colors, you can opt for either a varnished or non-varnished finish, giving you the flexibility to match your specific requirements.

1. Exceptional Electrical Insulation: Features high insulation resistance (≥ 1.0x10¹⁰ Ω) and volume resistivity (≥ 1.0x10¹⁰ Ω·m), ensuring excellent electrical safety and reliability.
2. High Dielectric Strength: The tubes boast a high dielectric breakdown voltage, with values up to 25 kV parallel to laminations and a surface withstand voltage of 12 kV, crucial for high-voltage applications.
3. Superior Mechanical Strength: With high flexural, compressive, and shear strength (e.g., G11 has a flexural strength of ≥ 200 MPa), these tubes provide robust structural support.
4. Low Water Absorption: A low water absorption rate of 1% ensures the material's electrical properties remain stable even in humid environments.
5. Excellent Thermal Performance: Available in thermal resistance grades B (for FR4) and F (for G11), the tubes can withstand a variety of temperature ratings without compromising performance.
6. Versatile Appearance: Tubes are available in a natural or green color, and can be varnished or non-varnished, providing flexibility for different aesthetic or functional requirements.
Q: What is the primary difference between FR4 and G11?
A: The main difference is their thermal resistance and mechanical strength. G11 has a higher thermal resistance grade (F vs. B) and superior mechanical strength, particularly at elevated temperatures, making it suitable for more demanding applications than FR4.
Q: Is the material flammable?
A: The material is inherently flame-retardant. It is often rated to UL 94-V0, meaning it will self-extinguish when exposed to fire.
Q: Can these tubes be machined?
A: Yes, these epoxy-fiberglass tubes are known for their excellent machinability. They can be cut, drilled, routed, and shaped to meet specific dimensional requirements.
Q: Do you offer custom sizes and diameters?
A: Yes, we can produce tubes with a variety of wall thicknesses and inside diameters to match your project specifications. Please contact us with your exact needs.
