Polyflon has taken advantage of the qualities of PTFE and coupled them with a proprietary plating process to produce a microwave substrate whose electrical performance cannot be equaled by any other substrate at this time.
Polyguide clad laminates and dielectrics are precision fabricated from the highest quality, high-density polyolefin available. Irradiation cross-linking of the polyolefin permanently imparts improved electrical homogeneity and mechanical toughness, while significantly enhancing the temperature and chemical resistance of the material. These laminates are impervious to solvents and solutions used in microwave circuit processing and fabrication.
Copper-Clad ULTEM® Data Sheet
Polyflon had added another microwave laminate to its product list. Polyflon's Copper-Clad ULTEM® laminates, made from the engineering amorphous thermoplastic PEI (Polyetherimide), have isotropic electrical and mechanical properties with exceptional thermal stability. The specific gravity of 1.27 is significantly less than that of competitive PTFE/Glass material. ULTEM® is a registered trademark of General Electric.
