Excellent Abrasion and Heat Resistance with PEKK Coated Discs

PEKK (Polyetherketoneketone) is a linear, aromatic, semi-crystalline thermoplastic, widely regarded as one of the highest performing thermoplastic materials in the world.

PEKK (Polyetherketoneketone) is a linear, aromatic, semi-crystalline thermoplastic, widely regarded as one of the highest performing thermoplastic materials in the world. Applied to the disc surface of Desponia® and Desponia® plus, it offers a cost-saving and long-term reliable solution for specific industrial applications, where high corrosion, abrasion and heat resistance are required.

Thanks to its outstanding properties, PEKK coated discs are ideal for use in:

– Discharge of filtered solids and slurries in chemical processes
– Slurry handling processes in the mining industry
– Flue gas desulphurization units in power generation plants
– Oil & Gas specific applications.

Typical configurations of Desponia® and Desponia® plus butterfly valves with PEKK coated discs cover combinations with Flucast® liners for abrasive applications and FPM liners for high temperature and aggressive applications.
