Product Texts
DESIGNATION ISO 12086-VDF/HFP-K, EG1N, N. ?E7.E.E.C.C,, ? (3-8)

KYNAR FLEX PVDF are fluorinated thermoplastic copolymers.

Outstanding characteristics of KYNAR FLEX : chemical resistance, 
imperviousness to UV, high barrier properties,high purity, good mechanical 
and thermomechanical properties.

Main applications of KYNAR FLEX : corrosion protection in the chemical 
industry, coating (painting, coextrusion), off shore, wire and cable.

KYNAR FLEX 2850 is a standard grade of granules less flexible than
the grade KYNAR FLEX 2800 with a higher melting point. For extrusion, wire
and cable constructions which require an UL temperature of 150°C.

Powder form available as KYNAR FLEX 2851.
