Technical overview
Thin and ultra-thin polyimide tape
These CGS grades use a 0.5 mil polyimide film backing with thin silicone adhesive coatings. Choose the total thickness and adhesive construction that fit your masking, insulation, and dimensional requirements.
CGS grades
| Part number | Film thickness | Adhesive | Total thickness | Adhesion to steel | Dielectric strength | Operating temperature |
|---|---|---|---|---|---|---|
| CGSTAPE-8257 | 0.5 mil | Thin silicone | 1.5 mil | 12.5 oz/in | 3,000 V/mil | 260°C |
| CGSTAPE-8257S | 0.5 mil | Ultra-thin silicone | 1.0 mil | 12.5 oz/in | 3,000 V/mil | 260°C |
These values come from the existing CGS Polyimide Tape grade table. Confirm current specifications and suitability for your process before production.
