PolyGrid provides a similar range of patterns and flexibility in a range of polymers, including Teflon and PFOA-Free expanded fluoropolymers.These ultra-thin, foil-gauge and thin-film materials offer infinitely variable geometry in three dimensions: Overall thickness or depth of pocket, open area and weight can all be precisely controlled for specific shielding characteristics. These metal foil and plastic film products are available from .001” thin, at up to 60” web width, with from 1 to 9,000 openings per square inch. Standard, diamond pattern sizes are available from .020” to 0.506”. Materials can be anodized, plated, painted or plastic coated, bent, formed, and punched. The variable open area facilitates lamination with a variety of other materials, including those which expand, contract and flex.
