Product Texts

Kynar® resins are fluorinated thermoplastic homopolymers.

Outstanding characteristics: chemical resistance, imperviousness to UV, high barrier properties, high purity, good mechanical and thermo-mechanical properties.

Kynar® 720 resin is a standard grade of granules for injection molding. This product is NSF/ANSI/CAN 61 certified. 

A powder form is available as Kynar® 721 resin.

Main applications:

• corrosion protection in the chemical industry
• coating (painting, co-extrusion)
• off shore
• wire and cable
