Photoetched polyimide films give designers low tooling costs, fast turnarounds, and rapid design changes for flat, intricate parts, including nonconductive washers, screens, and gaskets.
Photoeching 0.001 to 0.005 in-thick films also creates etched bend lines on parts that will be 3D formed. Polyimide's physical and chemical properties let photoetched parts serve in corrosive environments over a wide temperature range. The polymer also has good electrical insulating and limited spring properties.
