Lehvoss LUVOCOM® 1105-8344/EM/GY PEEK unreinforced, easy flowing  (discontinued **)
Categories: Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Unreinforced

Material Notes: Properties/attributes include: Especially suitable for medical parts, superheated steam sterilizable, hydrolysis resistance Highly chemically-resistant parts, non flammable. Inherent flame resistance.

Automotive industry, textile machinery, medical- and precision engineering, aircraft industry.

Processing: During processing, the moisture content should not exceed 0.05%. To avoid internal stresses, a medium to high injection rate should be used. An increase in tool temperature may be helpful. Post-crystallization may lead to warpage at elevated operating temperatures. This can be counteracted by suitable heat treatment. The processing notes provided merely represent a recommendation for general use. Due to the large variety of machines, geometries and volumes of parts, etc., it may be necessary to employ different settings according to the specific application. High-temperature polymers place increased demands on the tool steels employed.
