High VI PMA

Product Overview

Modern multigrade lubricant formulations require viscosity modifiers that control viscosity-temperature behavior across the intended operating range. Polymethacrylate technology provides formulators with a flexible polymer platform for developing lubricants with targeted viscosity index, rheological, and low-temperature characteristics.

High VI PMA is a Polymethacrylate (PMA) Viscosity Index Improver supplied by SiNDA through qualified international manufacturing partners for automotive and industrial lubricant applications.

High VI PMA is intended for lubricant formulations where higher viscosity-index targets, application-specific rheological characteristics, and formulation flexibility are important considerations. Actual performance and compatibility depend on polymer design, treat rate, base-oil system, additive-package chemistry, and finished-lubricant requirements.

Supported by available technical documentation, commercial shipment traceability, and international supply capability, SiNDA provides High VI PMA for professional lubricant manufacturers worldwide.

Technical Overview

High VI PMA uses polymethacrylate polymer technology to modify the viscosity-temperature behavior of multigrade lubricant formulations.

Its polymer architecture is intended to support viscosity index improvement and application-specific rheological performance in multigrade lubricant formulations. Depending on the specific grade, treat rate, and formulation, PMA technology can provide different combinations of thickening efficiency, shear response, and low-temperature characteristics.

Depending on polymer design and treat rate, High VI PMA may contribute to:

• Higher viscosity index
• Viscosity-temperature modification
• Grade-dependent low-temperature characteristics
• Multigrade viscosity control

• Compatibility with selected base-oil systems

Actual lubricant performance depends on polymer concentration, base-oil chemistry, additive interactions, and finished lubricant formulation.

Performance Characteristics

High Viscosity Index Improvement

High VI PMA is designed to increase the viscosity index of multigrade lubricant formulations, with the magnitude of improvement depending on polymer grade, treat rate, base-oil system, and finished formulation.

Potential formulation benefits include:

• Higher finished-oil viscosity index
• Improved viscosity-temperature performance
• Controlled viscosity-temperature behavior

• Support for multigrade formulation targets

Finished lubricant performance should always be verified according to the applicable industry specifications.

Low-Temperature Performance

Depending on polymer design and finished formulation, High VI PMA may contribute to low-temperature rheological performance.

Performance evaluation may include:

• Cold Cranking Simulator (CCS)
• Mini Rotary Viscometer (MRV)
• Pour Point
• Low-temperature storage stability

Final results depend on the complete lubricant formulation.

Shear Performance

The shear stability of High VI PMA depends on polymer molecular weight, polymer architecture, concentration, and application.

Evaluation may include:

• ASTM D6278
• ASTM D7109
• CEC shear stability procedures
• Application-specific laboratory testing

Published shear performance should always reference the corresponding test method and formulation.

Base Oil Compatibility

Depending on the specific grade and formulation requirements, High VI PMA may be evaluated with lubricant base stocks including:

• API Group I
• API Group II
• API Group III
• PAO-based formulations
• Selected ester-containing synthetic lubricants

Compatibility, solubility, finished-oil stability, and performance should be confirmed in the intended base-oil and additive system through formulation testing.

Selection Guidance

High VI PMA may be suitable for formulators seeking:

• High viscosity-index formulation targets
• Application-specific low-temperature performance
• Multigrade viscosity control
• Defined shear-performance objectives

• Flexible multigrade formulation development

Before commercial production, manufacturers should evaluate:

• Target SAE viscosity grade
• Target finished-oil viscosity index
• Low-temperature requirements
• Shear stability targets
• Polymer treat rate
• Base-oil compatibility
• Finished lubricant specifications

Laboratory validation is recommended prior to commercial implementation.
