KetaSpire® KT-820

PEEK made by Solvay 

KetaSpire KT-820 is a natural color, standard pellet of low flow, unreinforced polyetheretherketone (PEEK) that can be used in extrusion or injection molding applications. The pellet nature of this grade make it unsuitable for compression molding, however, powder and fine powder grades are also available for compression molding and compounding applications. KT-820 contains a lubrication package to help molded parts release from molds and to aid product conveyance in plastic processing equipment.  A non-lubricated product is also available.

KetaSpire PEEK is one of the highest performing materials in the thermoplastic market and is known for exceptional performance at elevated temperatures and excellent chemical resistance making it a true ultra polymer.
