Product Details
Alkyl Fumarate Vinyl Acetate Copolymer (Pour Point Depressant)
Alkyl Fumarate Vinyl Acetate Copolymer (commonly referred to as PPD) is a high-efficiency Pour Point Depressant designed for a wide range of industrial and automotive lubricants. As a critical component in cold-weather performance, this copolymer ensures that lubricants maintain fluidity at low temperatures, protecting machinery during cold starts and extreme environments.
As a leading lubricant additive manufacturer and factory, Chemost provides this additive to help blenders achieve precise low-temperature specifications while maintaining the cost-effectiveness of their formulations.
How It Works: The Science of Pour Point Depression
In paraffinic base oils, wax molecules tend to crystallize as temperatures drop. These crystals form a three-dimensional network that traps the oil, causing it to solidify (reach its "pour point").
Our Alkyl Fumarate Vinyl Acetate Copolymer functions as a wax crystal modifier. At low temperatures, the copolymer molecules are adsorbed onto the surface of the developing wax crystals or co-crystallize with the wax. This intervention:
Changes the growth direction of the wax crystals.
Prevents the formation of a rigid, interlocking lattice.
Maintains the liquid phase of the oil, allowing it to flow freely even when wax is present.
Achieving Low Pour Point: Why Use PPD?
There are three primary industrial routes to achieving a low pour point in lubricants. Understanding these helps in selecting the most economical and efficient production method:
Deep Dewaxing: Physically removing wax from the base oil. While effective, this significantly reduces the oil yield and negatively impacts the Viscosity Index (VI).
Isomerization Dewaxing: Converting linear wax molecules into branched structures. This is a high-performance method but involves extremely high capital and operational costs.
Moderate Dewaxing + PPD (The Chemost Advantage): By performing moderate dewaxing and then adding our Alkyl Fumarate Vinyl Acetate Copolymer, manufacturers can reach the desired pour point without sacrificing yield or VI. This is the most cost-effective solution for modern lubricant production.

Product Applications
Chemost’s Alkyl Fumarate Vinyl Acetate Copolymer is highly versatile and recommended for:
- Engine Oils: Improving cold-cranking properties in multi-grade oils.
- Gear Oils: Ensuring fluid movement in heavy-duty industrial and automotive gearboxes.
- Hydraulic Fluids: Maintaining system responsiveness in outdoor cold-weather operations.
- Base Oil Upgrading: Used by wholesalers and refineries to adjust the specifications of various base stock groups.
Guidance for Use
- Recommended Treat Rate: Generally $0.1\% - 1.0\%$ by weight, depending on the base oil origin and the desired pour point.
- Blending Temperature: It is recommended to blend at temperatures between to ensure uniform dispersion within the base oil.
Compatibility and Synergies
Our PPD is designed for excellent compatibility with other common lubricant additives:
- Viscosity Index Improvers (VII): Works synergistically with OCP and Polymethacrylate (PMA) viscosity modifiers.
- Additive Packages: Can be safely integrated into DI (Detergent-Inhibitor) packages for engine and hydraulic oils without precipitation or interference.
- Base Oils: Highly effective in Group I, Group II, and certain Group III base stocks.
Documentation and Quality Assurance
At Chemost, we understand the stringent requirements of B2B procurement and chemical manufacturing. We provide a complete documentation suite for every batch:
- Technical Data Sheet (TDS): Full performance profiles.
- Material Safety Data Sheet (MSDS): Global GHS compliance for safe handling and transport.
- Certificate of Analysis (COA): Batch-specific testing results ensuring consistency with your order specifications.
Frequently Asked Questions (FAQ)
Q: Does adding more PPD always result in a lower pour point?
A: Not necessarily. There is a "saturation point" beyond which adding more copolymer does not further lower the pour point. We recommend bench testing with your specific base oil to find the optimal treat rate.
Q: Is this product suitable for synthetic base oils?
A: Yes, it shows good performance in various synthetic blends, though the response rate may vary compared to mineral-based oils.
Q: Can you provide customized formulations?
A: As a manufacturer, Chemost can discuss specific molecular weight or viscosity requirements to suit specialized industrial applications.
