Polyimide Tape Thickness and Width Guide

“Mil” means one thousandth of an inch. For the standard single sided tapes below, the product's 1, 2, 5, or 10 mil label refers to the polyimide film backing. Total tape thickness includes the adhesive layer.

Standard single sided tape

Film backing Total tape thickness Roll length Shop silicone Shop acrylic
1 mil 2.5 mil 36 yards 1 mil silicone 1 mil acrylic
2 mil 3.5 mil 36 yards 2 mil silicone 2 mil acrylic
5 mil 6.5 mil 36 yards 5 mil silicone 5 mil acrylic
10 mil 11.5 mil 15 yards 10 mil silicone 10 mil acrylic

Compare the backing and total thickness with your clearance and handling needs. The 10 mil roll is shorter than the other standard rolls, so check length as well as unit price when comparing products.

Specialty constructions

The anti-static and black products list their available backing thicknesses on each product page. Double sided tape has adhesive on both sides: the 1 mil film version is 4 mil total, and the 2 mil film version is 5 mil total. See the double sided listings for the available options.

Choose a width

Standard single sided tapes offer widths from 1/8 in to 3 in. The Anti-static, black, and double sided listings begin at 1/4 in and also extend to 3 in; check each product's width selector for its exact options and availability. Choose a width that covers the area your process needs without obstructing adjacent parts.
