“Polypropylene – a Novel Thickener Technology with Many Surprises”

“Polypropylene – a Novel Thickener Technology with Many Surprises,” by Johan Leckner and René Westbroek received ELGI and NLGI Best Paper Awards.

Within this paper, you’ll find topics covering:

• The lubricating mechanism of polypropylene thickened greases in rolling element bearings differ significantly from that of soap based greases.
• These differences give rise to lower self-induced running temperatures, seven times longer grease life and a very effective replenishment mechanism.
• The differences presented in additive response, low temperature lubricity and behaviour when subjected to high temperature and oxidation promoting conditions.
