Product Details
Polymethacrylate (PMA) Pour Point Depressant
Product Category: Lubricant Additive Component
Chemical Name: Polymethacrylate
Abbreviation: PMA
CAS Number: [Insert relevant CAS, commonly 9011-14-7 depending on specific monomer]
Availability: Bulk Supply (Drums/IBC/Flexibags)
Product Overview
Chemost offers high-grade Polymethacrylate (PMA), a premier lubricant additive designed to serve dual functions: as a highly effective Pour Point Depressant (PPD) and as a Viscosity Index Improver (VII).
Designed for lubricant manufacturers and blending plants, our PMA series ensures optimal oil fluidity in cold environments. It is engineered to meet the rigorous demands of modern engine oils, gear oils, and hydraulic fluids, ensuring equipment protection during cold starts and operation in freezing climates.
Availability Note: We provide complete regulatory and technical documentation for global commerce, including
- TDS (Technical Data Sheet)
- MSDS (Material Safety Data Sheet)
- COA (Certificate of Analysis)
Mechanism of Action: How It Works
To understand the efficacy of our PMA additive, it is essential to understand the crystallization process of waxy crude oils:
Wax Crystallization: At low temperatures, paraffin waxes in base oils crystallize. Without treatment, these crystals grow and interlock to form a rigid 3D network, preventing the oil from flowing.
PMA Interference: As a Pour Point Depressant, the PMA molecule possesses a comb-like structure. It functions by adsorbing onto the surface of nascent wax crystals or co-crystallizing with the wax.
Crystal Modification: This interaction changes the direction of crystal growth and prevents the crystals from agglomerating into a network. The result is smaller, separate crystals that allow the oil to remain fluid at significantly lower temperatures.
Technical Concepts: Pour Point vs. Solidification Point
In the formulation of lubricants, distinct temperature metrics define performance. Our PMA additives are tested against strict industry standards to optimize both:
Pour Point (The Critical Metric): This is the lowest temperature at which the lubricant retains the ability to flow. In practical applications, the Pour Point is the most accurate indicator of the lubricant's actual minimum operating temperature.
Solidification Point : This is the highest temperature at which the lubricant loses its fluidity (stops flowing) when cooled under specific conditions.
Chemost PMA additives significantly lower the Pour Point, extending the operational range of your finished lubricants well below standard base oil limits.
Applications & Usage Guidelines
Our Polymethacrylate PPD is versatile and suitable for formulating various lubricant types:
1. Internal Combustion Engine Oils:
Used to improve cold crank viscosity (CCS) and ensure oil pumpability during cold starts.
2. Gear Oils & Transmission Fluids:
Provides necessary low-temperature fluidity to protect gears before the system reaches operating temperature.
3. Hydraulic Fluids:
Essential for outdoor hydraulic equipment operating in winter conditions to prevent pump cavitation.
Recommended Treat Rate
The optimal dosage depends on the base oil type (Group I, II, III, or PAO) and the wax content.
General Dosage Range: 0.1% – 1.0% (wt)
Note: Over-dosing usually does not yield better results and may lead to "reversion." We recommend optimization testing (ladder study) in your specific base oil.
Compatibility & Handling
Synergy and Compatibility:
Base Oils: Excellent solubility in Group I, II, and III mineral oils, as well as PAO (Polyalphaolefins).
Additive Packages: Fully compatible with standard detergent/dispersant packages, ZDDP, and other functional additives.
Reversion Warning: Care should be taken when using PMA with other types of PPDs (such as Alkyl Naphthalene) to avoid antagonistic effects.
Storage:
Store in a dry, cool, and well-ventilated area. The recommended maximum handling temperature is 60°C. Shelf life is typically 24 months when stored properly in unopened containers.
Frequently Asked Questions (FAQ)
Q: Can this PMA additive serve as a Viscosity Index Improver (VII) as well?
A: Yes. Polymethacrylates (PMA) are unique because they naturally possess high Viscosity Index improving capabilities. While primarily used for pour point depression, they simultaneously improve the viscosity-temperature relationship of the oil.
Q: Do you offer samples for lab testing?
A: Yes. As a partner to lubricant manufacturers, we understand the need for pilot testing. Please contact our sales team to request a sample for your lab.
Q: What is the difference between PMA and other PPD chemistries like Naphthalene?
A: PMA generally offers better performance in modern Group II and Group III base oils compared to traditional Naphthalene-based PPDs. PMA also offers the secondary benefit of VI improvement, which Naphthalene types do not.
Q: Are documents like TDS, MSDS, and COA provided with the shipment?
A: Absolutely. A Certificate of Analysis (COA) accompanies every shipment. TDS and MSDS are available for download or via email upon inquiry.
