Description
Polymethacrylate PMA PPD is a high effective light yellow or colorless transparent liquid. It shows good pour point depression ability and low temperature performance, meanwhile, it can improve viscosity index and it has some effect on the viscosity.
Application
Polymethacrylate PMA PPD is used to make aviation hydraulic oil, hydraulic transmission oil, gear oil, low freezing point hydraulic oil, multigrade internal- combustion engine oil, etc.
Reference Dosage
The dosage is from 0.1% to 1.0%.
