POLYETHERKETONE POLYMERS AND COPOLYMERS  

Ketonex proprietary processes are used to produce a wide range of polyetherketone polymers and copolymers. Thermal and mechanical property modifications are achieved by the introduction of both in-chain and end-chain functionality. In addition, melt viscosity is controlled and easily adjusted. Materials may be amorphous or semi-crystalline, in which case the rate of crystallisation and ultimate degree of crystallinity may be modified.  

Materials can be produced directly, without further processing, in the form of      

• Powder – suitable for selective laser sintering, 40 – 100 µm diameter -          
• Flake – which may be converted to strand for fused deposition modelling  

Ketonex materials exhibit properties such as          

• High operating temperatures, with Tg 70 – 200 °C          
• Comparatively low melting temperatures with manageable processing temperatures          
• High purity        
• Controlled degree of crystallinity          
• Excellent thermal stability         
• Excellent mechanical properties        
• Good adhesion to carbon fibre and aluminium,

in addition to other properties characteristic of polyetherketones such as low toxicity, chemical resistance, electrical insulation, fire retardency and low smoke emission.
