A Detailed Explanation of PMA Pour Point Depressant--- The Hero behind Antifreeze Lubricating Oil
The mechanism of action of PMA pour point depressant is mainly based on the following two points:
- Inhibit the formation of wax crystals
At low temperatures, the paraffin components in lubricating oil will crystallize and precipitate, causing the oil to thicken or even solidify. PMA molecules can adsorb onto the surface of wax crystals, preventing their further growth and aggregation, thereby maintaining the fluidity of lubricating oil.
- Improve low-temperature pumpability
Even if the lubricating oil has not completely solidified, the presence of wax crystals may clog the filter or oil passage. PMA pour point depressant can reduce the size of wax crystals, ensuring that the oil can still be smoothly pumped to key parts at low temperatures.
The advantages of PMA pour point depressant:
High-efficiency pour point reduction: Significantly lowers the pour point of lubricating oil, adapting to extreme environments of -30℃ or even lower.
Strong compatibility: It has good compatibility with various base oils (mineral oil, synthetic oil) and other additives (such as viscosity index improvers).
High stability: Heat-resistant, oxidation-resistant, and not prone to decomposition or failure even after long-term use.
Environmental protection and safety: Complies with modern environmental protection standards and does not release any harmful substances.
