| About |
|---|
| Kynar® resins are fluorinated thermoplastic homopolymers. Outstanding characteristics: chemical resistance, imperviousness to UV, high barrier properties, high purity, good mechanical and thermo-mechanical properties. Main applications: corrosion protection in the chemical industry, coating (painting, co-extrusion), off-shore, wire and cable, water transportation. Kynar® 740 E resin is a standard grade of granules for extrusion of tubes and plaques, compression and transfer molding. This product is ANSI/NSF Standard 61 certified. This product is compliant with the EU positive list.&& |
