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.
