Fiberglass tape

Fiberglass tape is a high-performance electrical insulation tape produced with premium E-glass fibers, impregnated with special thermosetting polyester resin. Its pliable and tacky nature ensures easy handling, secure application, and delamination resistance. The unique web structure allows effortless unwinding, preventing strand separation or overlapping. Suitable for extreme-temperature insulation and high-strength reinforcement, it offers reliable performance in the most demanding applications.

Description

SIDA fiberglass tape is designed for versatile use in high-temperature, high-voltage, and mechanically demanding environments. Manufactured using parallel twisted E-glass yarns and a durable thermosetting polyester resin, this tape achieves insulation class C (200°C), making it ideal for electrical insulation and mechanical protection. The tape maintains pliability and tack, ensuring easy application without fraying or splitting. Its web structure ensures controlled, smooth unwind, facilitating precision in banding, wrapping, and reinforcement tasks.

Key performance advantages include:

  • Excellent electrical insulation with high dielectric strength.

  • Exceptional thermal resistance suitable for Class C (200°C) insulation systems.

  • Strong resistance to chemicals, moisture, and aging.

  • Retention of mechanical strength under extreme conditions.
