Epoxy Fiberglass Tube

The Epoxy Fiberglass Tube is manufactured using alkali-free glass fabric bonded with epoxy resin. Produced through heat-rolling, tightening, baking, and curing processes, this product exhibits high mechanical properties and maintains stable electrical properties even in high-humidity environments. It is suitable for use as insulation structural parts within mechanical, electrical, and electronic equipment.

Standards and Classification We offer tubes compliant with various international standards:

• GOST Standard: 3640

• NEMA Standard: G10, FR4, G11, FR5

• IEC Standard: EPGC21, EPGC22, EPGC23

Type Characteristics

• 3640: Features higher mechanical and electrical insulating properties with low water absorption. Designed for insulating structural parts in electric apparatus.

• EPGC Series:

  • **EPGC21:**Maintains stable electrical insulating properties under heavy humidity. Used in mechanical, electrical, and electronic applications.

  • EPGC22: Similar to EPGC21 but offers superior mechanical properties under high temperatures.

  • EPGC23: Similar to EPGC21 but includes fire retardant properties.

• NEMA Series (G10, FR4, G11, FR5):

  • All types possess excellent mechanical strength, dielectric loss properties, and electric strength in both dry and humid conditions.

  • G10 & FR4: Share the same mechanical and electrical properties; FR4 adds fire retardant properties.

  • G11 & FR5: Offer higher thermal properties compared to G10 and FR4; FR5 adds fire retardant properties.
