What is the composition of pour point depressant(PPD)?
Pour point depressants (PPDs) are additives used in lubricants and fuels to lower the pour point, which is the temperature at which the fluid becomes too thick to flow freely. By reducing the pour point, these additives help maintain fluidity and pumpability at lower temperatures, especially in cold climates. The specific composition of pour point…
