Collection: Polyester Tape

Polyester is a very thin film, a few hundredths of a millimetre, and yet hard to stretch. A polyester tape therefore brings negligible thickness, a clean cut that does not stretch under the blade, and good temperature resistance.

Its most frequent use: high temperature masking

A paper masking tape degrades in the oven and leaves a baked-on residue that is very hard to remove. Polyester withstands much higher temperatures and comes off cleanly after the oven.

That makes it the masking tape before powder coating, anodising or heat treatment. Always check the stated maximum temperature and the associated exposure time: the two go together.

What it does not do

Polyester does not conform. On a curved or irregular surface, it wrinkles and lifts at the corners. In those cases, a more flexible cloth or vinyl tape remains preferable.
