Ensinger PEI

(Viewing data as-entered. Click here to return)
Lehmann & Voss LUVOCOM® 1800-8449 PET with carbon fiber
Categories: Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET)

Material Notes: Properties/attributes include: High-strength and stiffness parts with low creep. Electrically conductive, suitable for continuous discharging of statically-generated electricity. For dynamic stress and wear resistance

Automotive industry, textile- and office machinery, apparatus- and precision engineering. Typical uses include: Bearings, sleeves, control disks, gear wheels, cams.

Processing: During processing the moisture level should not exceed 0.02%, otherwise molecular degradation and surface defects (e.g. smearing) may occur. As the material absorbs water very quickly, the predried material should be fed to the processing immediately. Processing temperatures above 300°C may very rapidly cause thermal damage and should therefore be avoided. 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.
