【Performance and Application】
1. As low foam detergent or defoamer
2. L61, L64 for preparing low foam, high cleaning power synthetic detergents;
3, L61 is used as defoamer in paper or fermentation industry;
4, Polyethers are useful antistatic agents, L44 provides long-lasting static protection for synthetic fibers.
5, Polyethers are used as dispersants in emulsion paints. L62, L64 can be used as emulsifiers for pesticides, and as coolants and lubricants in metal cutting and grinding. They are also used as lubricants during rubber vulcanization.
6, Polyether can be used as crude oil demulsifier, L64 can effectively prevent the formation of hard scale in oil pipelines, and can be used for the recovery of secondary oil.
