Flame retardant electrical tape for coils and transformers

The C8020 is a flame retardant electrical tape in a black polyester acetate cloth construction: B-class self-extinguishing, high dielectric strength, and resistant to moisture and mildew. That combination is why it is specified as a flame retardant electrical tape for coils, transformers and motors, where the tape is part of the insulation system rather than just a means of holding a bundle together.

Because it is hand-tearable and conforms to curved coil ends, it is also a practical flame retardant tape for repair and rewinding work. Where the requirement is a general-purpose flame retardant tape for bundling, a PET cloth grade such as the B1300 covers it at lower cost.

Acetate tape: common questions

Is this an acetate tape or a cloth tape?

Both. Acetate tape is the common short name for a polyester Acetate Cloth Tape — a woven acetate cloth backing, not a film.

What flame rating does it hold?

B-class self-extinguishing flame retardancy. Ask for the test data with your quotation if the rating has to go into an approval file.

Where is acetate tape used instead of PVC tape?

Inside coils and transformers. PVC tape is a film tape for wiring and colour coding; acetate tape is an insulating tape that has to follow a curved winding and hold its dielectric strength in humid conditions.

Is there a difference between acetate tape and acetate fabric tape?

No. Acetate fabric tape, acetate cloth tape and acetate tape describe the same woven polyester acetate backing — the names differ by supplier and by region.

Can this be used as acetate cloth insulation tape in a class F winding?

It is commonly specified as acetate cloth insulation tape for layer and end-turn insulation. Send us the insulation class and the layer thickness and we will confirm whether the construction fits, or whether a polyimide tape is needed.
