Pour Point Depressant
Pour Point Depressant (PPd) are petroleum additives blended into lubricants to lower the minimum temperature at which the lubricant or fuel will flow. PPd are used to improve fuel and lubricant performance in cold weather and although all lubricants possess a pour point, the addition of PPd may cause the pour point to be significantly…

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…
