Tribology of polypropylene and Li-complex greases with ZDDP and MoDTC additives [PDF]
, 2017 The influence of thickener and additive interactions on grease lubricating performance is examined. Polypropylene and lithium complex thickened (Li-complex) greases were tested both as neat greases and with a 2 wt% addition of ZDDP and/or MoDTC.
