Pour Point Depressants (PPD) are polymers which lowers the temperature to suppress the precipitation of hydrocarbons present in oil. Pour Point Depressants are also known as paraffin inhibitors. Pour point depressants interlocks the waxy materials or paraffin by co-crystallization and modify the shape of crystals to increase the fluidity of oil or fluid. Good quality pour point depressants lowers the pour point up to 400C. However, poly methacrylate and alkyl aromatic ... Read more
