In addition to materials such as tungsten, titanium, elgiloy, MP35N, nitinol, and polyimide film, Tech-Etch (Plymouth, MA) has now developed a process to photochemically etch polyester sheets up to .010" thick. All of the advantages of photo etching, clean burr-free edges, the ability to create intricate features with minimal tooling cost, and fast delivery, can now be applied to this high-strength, hydrophobic, solvent-resistant, optically clear material. Features include:
• Polyester sheet that can be depth-etched with grooves or channels unavailable with other manufacturing methods.
• Applications that include dielectrics, diaphragms, gaskets, washers, discs, spacers, seals, caps, and insulators.
