3M Heat Resistive Polyimide Tape 7418F
3 Inch | Brown | Polyimide film
3M™ Heat Resistive Polyimide Tape 7418F is a heat resistive polyimide process tape. 3M tape 7418F consists of thermally cross-linkable acrylic copolymer that provides good initial adhesion but has less adhesion build-up even after high temperature processes.
Key Features
- Polyimide film provides excellent dimensional stability at elevated temperatures.
- Silicone adhesive offers reliable high-temperature performance with reduced adhesive transfer.
- Suitable for PCB solder masking and other demanding high-temperature applications.
- Flame retardant, chemical resistant and radiation resistant for reliable surface protection.
- Provides a clean release surface and helps reduce adhesive residue after removal.
- Halogen-free tape designed for demanding electronic and industrial applications.
