Lubricating grease production in North America increased 4.6 percent in 2017, according to the National Lubricating Grease Institutes yearly survey, which was released last week. Production of greases made with aluminum soap, calcium soap and lithium soap thickeners showed growth, while those made with polyurea experienced a decline.
The 45 North American grease plants that participated in the survey produced about 473.9 million pounds of grease last year, or 18.3 percent of the global total of 2.6 billion pounds.
Officials with the United States-based NLGI emphasize that grand totals should not be used year-to-year comparisons of data because the pool of reporting companies can shift.
Comparative data for consistently reporting companies in North America showed an increase of 4.6 percent in total grease production from 2016 to 2017.
The percentage of greases made with conventional lithium soap thickener accounted for 25.3 percent of grease production in the region in 2017, down from 27.2 percent in 2016. The percentage made with lithium complex soap thickeners made up 42.2 percent of the regions demand in 2017, compared to 41.1 percent in 2016.
Calcium soap grease production accounted for 11 percent of the regions grease production last year, up from 10.4 percent in 2016. Aluminum soap greases made up 11 percent of the regions production in 2017, up from 6.2 percent in 2016.
Aluminum soap grease production increased 25.9 percent from 2016. Calcium soap grease production in North America was up 10.3 percent in 2017. Total lithium soap production in North America was up 3.5 percent from 2016. Polyurea grease production was down 7.6 percent from 2016.
Caribbean, Central and South America
In the Caribbean, Central and South America, 14 grease plants participating in the survey produced 80.7 million pounds of grease in 2017, accounting for 3.1 percent of the 2.6 billion pounds of global production. Comparative data wasnt available for the region.
The percentage of greases made with conventional lithium soap thickener accounted for 73.2 percent of such production in the region in 2017. Grease made with lithium complex soap thickeners made up 15 percent of the regions production in 2017. Production of grease made with calcium soap accounted for 9.2 percent, while grease made with sodium soap thickener made up 2 percent of the regions grand total.
The full 30-page report of 2017 grease production includes prior-year data going back to 2014, and will be available to download by the end of June at www.nlgi.org. NLGI member companies can obtain a free copy, and nonmembers may purchase the report, which contains data categorized by geographic region, thickener type, base oil type and year.
