Plymouth, MA....Tech-Etch is well known for the extensive list of exotic materials the company is capable of photo etching. In addition to materials such as tungsten, titanium, elgiloy, MP35N, nitinol, and polyimide film, Tech-Etch has now developed a process to photochemically etch polyester sheet 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. Polyester sheet can also be depth etched with grooves or channels unavailable with other manufacturing methods. Applications include dielectrics, diaphragms, gaskets, washers, discs, spacers, seals, caps and insulators.
