How Does Pour Point Depressant Work？
PPD is a polymer or condensate whose molecules generally comprise a chemical composition similar in polarity to a polar group (or aromatic core) and a paraffin alkyl chain. Usually a small amount of addition can significantly reduce the apparent viscosity of the oil and the freezing point of the yield value, thereby achieving improved oil and low temperature fluidity. Therefore, it is also referred to as PPD of a low temperature flow improver. The pour point depressant can quickly reduce the freezing point of the oil, effectively refine the wax crystal, reduce the cold filter point and further improve the low temperature fluidity of the oil, and is a new generation of high-tech products.
