Arkema is now offering Kynar® 3312C, an innovative and flexible conductive PVDF grade for use in applications where flammable liquids are handled, mainly in automotive and chemical applications. This new grade limits the generation of electrostatic discharge, and offers improved flexibility for sophisticated designs of fuel lines and chemical systems.
Kynar® 3312C displays excellent flexibility and ductility while retaining high melting point and extreme chemical resistance. This new grade is complementary to Kynar® 340, the first conductive PVDF grade commercialized by Arkema. Kynar® 3312C shows improved processability for the extrusion of flexible tube and for injection molding. The following table presents the new range of conductive Kynar® PVDF grades offered by Arkema.
Kynar® 340 Kynar® 3312C
Resistivity (ohm.cm) < 10 000 < 10 000
Flexural modulus (MPa) 1600 1080
Melt viscosity (Pa.s) 2500 2050
Elongation at break (%) >20 >150
Like other Kynar® PVDF fluoropolymers, this new grade is highly resistant to chemical corrosion (acids, halogens and solvents,) abrasion, and UVs, and offers thermal resistance up to 150ºC. Its exceptional UV resistance and weatherability make it an excellent material for outdoor applications.
