PPD (Pour Point Depressants)

PPD (Pour Point Depressants)Pour Point Depressants (PPD) are critical components that prevent wax fractions in the base oil from forming large crystal networks which inhibit lubricant flow at cold temperatures. Lubrizol offers a range of PPDs based on Polymethacrylate (PMA) and Styrene Ester chemistries that can meet the needs of virtually any lubricant formulation. These include products optimized for Group I and the latest Group II and III base oils which dominate engine and driveline lubricant formulations.
