Rulon Bearings

Lehvoss LUVOCOM® 1850-8023 PBT with carbon fiber
Categories: Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET)

Material Notes: Properties/attributes include: Electrically conductive, suitable for continuous discharging of statically-generated electricity. Strong, stiff parts. Reduced moment of inertia compared with metal parts.

Automotive industry, textile- and office machinery, apparatus- and precision engineering.

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 270°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.
