A manufacturer of lubricants has developed a fully synthetic, high-viscosity grease for the lubrication of plastic parts inside cars. Klüber Lubrication says its Klübersynth RA 44-702 does not contain any silicone and mechanically dampens and reduces noise of slowly moving parts. The grease, which has no odor, can be used for both plastic/plastic and plastic/metal material pairings.
