What Polyflon does
Polyflon is a specialty RF/microwave materials manufacturer operating as a brand under Crane Aerospace & Electronics, a subsidiary of Crane Co. (NYSE: CR). The company designs and manufactures high-performance microwave substrate laminates, specialty capacitors, and RF components from its West Caldwell, NJ facility, serving defense, space, commercial, medical, and industrial markets. Named programs include U.S. Navy shipboard radar and the Over-the-Horizon radar system, alongside historical commercial engagements such as Western Electric cell-site tower distribution boards.
The core technology is a proprietary PTFE (polytetrafluoroethylene) electroplating process acquired from S.W. Farber, which enables Polyflon's flagship CuFlon substrate — a pure PTFE dielectric with copper plating that delivers extremely low moisture absorption, isotropic behavior, and uniform electrical properties over frequency. The product portfolio spans CuFlon (premier PTFE substrate), NorCLAD (low-Dk material for microstrip patch antennas), POLYGUIDE (irradiated HDPE laminates acquired from SRT in 1994 offering PTFE-comparable performance at one-third the cost), PolyPlate (copper-plated PTFE shapes), and Polyflon Bonding Film (thermoplastic film for multilayer circuits). Registered trademarks across the product line and over 60 years of domain experience underpin the technical position.
Polyflon operates an enterprise B2B go-to-market with regional salespeople, online RFQ functionality for commercial and military inquiries, and a documentation-rich website hosted under the Crane AE corporate domain. Revenue is generated exclusively through hardware sales of materials and components; pricing is quote-based and not publicly disclosed, with multi-year contracts noted. Polyflon has been a wholly-owned brand of Crane Co. since 1985, leveraging the parent's global footprint across 26 countries while maintaining a focused substrate and specialty components portfolio.

Polyflon product offering
Product offeringCore offering
Polyflon designs and manufactures high-performance RF and microwave substrate materials (CuFlon, NorCLAD, POLYGUIDE, Polyflon Bonding Film, PolyPlate) and specialty RF/microwave components, including custom-built capacitors, for defense, space, commercial, medical, and industrial scientific applications. Its core competency is proprietary PTFE electroplating combined with irradiated polyolefin lamination, delivering low-loss, dimensionally controlled substrates for amplifiers, couplers, microstrip circuits, stripline packages, and antennas.
Product overview
Polyflon is a supplier of RF/Microwave laminates, substrates, capacitors, and specialty components serving the commercial, medical, and military markets. The product portfolio centers on microwave substrate materials: CuFlon (premier pure PTFE substrate with proprietary copper plating), NorCLAD (designed for microstrip patch antenna applications), POLYGUIDE (irradiated polyolefin laminates for antennas and couplers), and Polyflon Bonding Film (thermoplastic film for stripline and multilayer circuits). The company also offers PolyPlate, an array of copper-plated PTFE shapes. Polyflon was acquired by Crane Co. in 1985 and operates from West Caldwell, NJ, with over 60 years of experience in microwave component manufacturing.

Products and services
- CuFlon CuFlon is Polyflon's premier microwave substrate material featuring a pure PTFE dielectric with copper plating via Polyflon's proprietary process. It offers extremely low moisture absorption, isotropic properties, and uniform electrical properties over frequency, and is an excellent solution for producing amplifiers and couplers. Available with copper coatings as thin as 1/16 oz./ft.² and dielectric thicknesses as low as 0.00025 in. (6 µm).
- NorCLAD NorCLAD is a microwave substrate with a low dielectric constant (2.55) and low dissipation factor (0.0011 at 3 GHz), ideally suited for microstrip patch antenna designs including stacked microstrip patch antenna applications. It features good thermal performance with an operating temperature range of -55°C to +125°C and is frequently used for GPS receiver and WLAN router antennas.
- POLYGUIDE POLYGUIDE laminates are manufactured from highest-quality, high-density irradiated polyolefin. The irradiation imparts improved electrical homogeneity, mechanical toughness, enhanced temperature performance, and chemical resistance. The laminates offer superior electrical properties up to at least 10 GHz at approximately one-third the cost of PTFE, and are an excellent solution for commercial antennas, couplers, and other microwave products where low loss is critical.
- Polyflon Bonding Film Polyflon Bonding Film is a low-melting-point thermally-stabilized polyolefin thermoplastic bonding film (0.002 in./51 µm thick) developed for stripline packages and multilayer circuits. It features low dielectric constant and low loss tangent at microwave frequencies, and is RoHS compliant.
- PolyPlate PolyPlate is an array of PTFE shapes plated with copper, developed as Polyflon began marketing its unique PTFE electroplating capabilities for RF and microwave applications. It represents one of Polyflon's early commercial product lines using its proprietary electroplating process.
- Specialty RF/Microwave Components and Custom-Built Capacitors Custom-built specialty RF/microwave components and capacitors manufactured by Polyflon for defense, scientific, industrial, medical, and space applications. Historical examples include a custom-built capacitor employed in the U.S. Navy large shipboard radar program and custom-built, fixed-value capacitors for the Over-the-Horizon radar program.
