HOW FRIENDLY ARE BIO-BASED GREASES WITH OTHER GREASES?

Dr. Anoop Kumar and Bill Mallory

Royal Mfg Co. LP, USA

Presented at NLGI's 79th Annual Meeting, June, 2012, Palm Beach, Florida, USA

1.     Introduction

The applications of lubricants based on vegetable oils/animal fats were known to mankind since our ancient past and continued to be used until the 19th century when they were suddenly replaced by mineral oil, and to a lesser extent, by synthetic oil based lubricants and greases [1-2]. These mineral oil based and/or synthetic oil based greases have continued to dominate even today. The NLGI 2010 Grease Production Survey indicates over 2.3 billion lbs. of total worldwide grease volume were mineral oil based greases which dominated by about 93%, followed by synthetic and semi-synthetic oil based greases, or about 3% each. Biobased greases found their entry for the first time in this survey, though only about a 1% market share [3].

OVERBASED CALCIUM SULFONATE GREASES FOR EXTREME ENVIRONMENT

Dr. Anoop Kumar, Steve Humphreys and Bill Mallory

Royal Mfg Co. LP

Published by: Greasetech India Vol XIV, No. 3 January  - 1 March 31, 2012

Abstract:

There are number of grease thickeners available for making lubricating greases. However, each one of them possesses its own strengths and weaknesses.

Calcium sulfonate complex greases, not new to the industry, are known for over six decades and have been improved over times by various people to make suitable grease for different applications. This class of grease is known for having excellent high temperature, extreme pressure and rust protection characteristics. The down side of its performance is poor pumpability, poor low temperature properties and higher cost compared to lithium greases.
