Greene Tweed WR™ 300 PEEK, Carbon Filled
Categories:	Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Carbon Fiber Filled
Material Notes:	WR®300 is a carbon-fiber reinforced compression molded PEEK often selected by pump manufacturers and users for pump bushings and case or impeller wear rings. Maximum service life is achieved in clean, lubricated and/or moist environments. WR300 allows the pump user to increase pump efficiency by running tighter wear ring clearances while decreasing potential pump damage when pumps are cavitated or experience radial bearing failures. Information provided by Greene Tweed.
Vendors:	Ensinger TECAPEEK™ shapes are manufactured exclusively with Victrex™ PEEK polymer. The Ensinger process and Victrex resins ensure reliability, consistency, dimensional stability, and high temperature mechanical performance.
