Polymethacrylates (PMAs) are among the most versatile viscosity modifier chemistries available to lubricant formulators. PMA technology can provide viscosity index improvement, excellent permanent shear stability, low-temperature performance, dispersancy, and compatibility across petroleum, synthetic, and bio-based fluids. This versatility makes PMAs particularly useful when finished-fluid requirements extend beyond simple thickening.
The versatility of PMA chemistry also means that product selection matters. Functional Products works with formulators to identify the appropriate PMA technology for the required viscosity profile, shear stability, low-temperature properties, base oil system, and overall formulation objectives, the required viscosity profile, shear stability, low-temperature properties, base oil system, and formulation economics.
Functional Products manufactures a broad range of PMA technologies for different lubricant applications:
- FUNCTIONAL MH | Hydraulic Grades: PMA viscosity modifiers offering a range of thickening efficiencies and shear stabilities for high-VI and multigrade hydraulic fluids.
- FUNCTIONAL MG | Gear Grades: Shear-stable PMAs designed for multigrade gear oils and other applications requiring excellent viscosity retention under mechanical shear.
- FUNCTIONAL MB | Synthetic Base Stocks: Low-molecular-weight PMA technology combining viscosity and viscosity index contribution with excellent permanent shear stability.
- FUNCTIONAL MN | Naphthenic-Based Grades: PMA viscosity modifiers supplied in naphthenic carrier oils for formulations requiring the properties and compatibility of a naphthenic oil system.
- FUNCTIONAL MD | Dispersant PMAs: Functionalized viscosity modifiers combining viscosity index improvement with dispersant properties for applications such as tractor fluids, automatic transmission fluids, and other long-life lubricants.
Functional Products also manufactures proprietary pour point depressants (FUNCTIONAL PD) for mineral, biobased, and synthetic fluids.
