Arkema Inc. (King of Prussia, PA, US) announced April 9 that new Kynar PVDF and Kepstan PEKK based filaments are now available in 1.75mm and 2.85mm diameters from 3DXTech (Byron Center, MI, US) and are marketed under the Firewire trademark. 

Kynar PVDF has been trusted for decades in the most demanding industrial applications, requiring resistance to a wide range of aggressive chemicals. PVDF exhibits high thermal stability up to 150°C and extreme durability in direct sunlight exposure.

Kepstan PEKK is an extreme performance thermoplastic with a highly stable chemical backbone.  Its semicrystalline structure offers a combination of mechanical and thermal strength together with chemical and fire resistance.  The Kepstan PEKK filaments offer both ease of printability and the highest performance of any thermoplastic material currently available.
