Static-Control Kynar ® PVDF CN
(PolyVinyliDene Fluoride) Specifications

GENERAL DESCRIPTION

Kynar ® PVDF has excellent corrosion and chemical resistance and performs in many applications up to 300°F (149°C). It is used extensively in chemical processing applications because of its unique combination of properties. PVDF possesses excellent chemical resistance, is tough and durable, and is easily fabricated into finished parts.

By adding special conductive materials to the resin, the conductivity of PVDF is increased to control static electricity formation or conduction. These additives may be in the form of either carbon fibers (PVDF CN-F) or carbon powder (PVDF CN-P). Some properties of the original PVDF material are modified by the addition of fillers, but chemical resistance, strength, and manufacturability remain generally the same.

Both PVDF CN-F and PVDF CN-P are available in BLACK color only.

( see also Standard PVDF Specifications )
Static Dissipative / Anti-Static (SD) :
Resistivity generally between 10 7 and 10 12 ohms per square.  Initial electrostatic charges are suppressed.

Conductive (CN) :
Resistivity generally between 10 3 and 10 6 ohms per square.  No initial charge, provides path for charge to bleed off.
