Operational Applications

High VI OCP is designed for lubricant manufacturers developing formulations that require a high viscosity index and stable viscosity performance across a broad operating temperature range.

Typical applications include:

• Passenger Car Motor Oils (PCMO)
• Heavy-Duty Diesel Engine Oils (HDEO)
• Multigrade Engine Oils
• Hydraulic Oils

• Industrial Gear Oils
• Compressor Oils
• General Industrial Lubricants

Application suitability should be verified through formulation development and finished lubricant performance testing.

Technical Overview

High VI OCP is an ethylene–propylene olefin copolymer viscosity index improver engineered to maximize viscosity index enhancement while maintaining reliable thickening performance and formulation stability.

The polymer modifies the viscosity-temperature relationship of the lubricant by reducing the rate at which viscosity decreases as operating temperature increases. This enables lubricant manufacturers to formulate multigrade oils with improved viscosity stability over a wide temperature range.

Different OCP technologies are optimized for different formulation priorities. High VI OCP is intended for applications where maximizing viscosity index is the primary formulation objective. Unlike High Molecular Weight OCP, which emphasizes thickening efficiency, or High Shear Stable OCP, which prioritizes resistance to permanent mechanical shear, High VI OCP is specifically optimized for achieving higher finished-oil viscosity index values.

Final lubricant performance depends on the selected base oil, additive package, polymer concentration and target viscosity grade.

Performance Characteristics

Superior Viscosity Index Improvement

The polymer is designed to maximize viscosity index enhancement, allowing lubricants to maintain more consistent viscosity across low and high operating temperatures.

Benefits include:

• Higher finished-oil viscosity index
• Improved viscosity-temperature characteristics
• Better multigrade performance
• Enhanced formulation flexibility
• Stable lubricant performance over a wide temperature range

Reliable Temperature-Viscosity Performance

High VI OCP contributes to maintaining lubricant viscosity under varying operating temperatures.

This supports:

• Improved cold-start viscosity behavior
• Stable operating viscosity at elevated temperatures
• Consistent lubricant performance
• Reliable viscosity control throughout the operating range

Final performance should always be confirmed by finished-oil laboratory testing.

Balanced Thickening Performance

The product provides effective viscosity building while prioritizing viscosity index improvement.

Actual thickening efficiency depends on:

• Base oil viscosity
• Polymer concentration
• Finished viscosity grade
• Formulation design

Treat rate should be optimized during formulation development.

Reliable Blending Performance

High VI OCP is supplied as an oil-based polymer concentrate suitable for conventional lubricant manufacturing.

Under recommended blending conditions it provides:

• Uniform polymer dissolution
• Consistent production batches
• Reliable formulation repeatability
• Stable blending performance

Complete dissolution should be confirmed before adding temperature-sensitive additives.

Base Oil Compatibility

High VI OCP is compatible with:

• Group I Base Oils
• Group II Base Oils
• Group III Base Oils

Compatibility should be verified when formulating with synthetic base stocks or highly paraffinic Group III oils.

Recommended validation includes:

• Polymer dissolution
• Finished oil clarity
• Storage stability
• Filterability
• Low-temperature properties
• Finished-oil viscosity index

Compatibility and Limitations

High VI OCP is intended for lubricant formulations where maximizing viscosity index is the primary objective.

Performance depends on:

• Base oil selection
• Polymer treat rate
• Additive package compatibility
• Target SAE viscosity grade
• Low-temperature performance
• High-temperature viscosity requirements

Although the product significantly improves viscosity index, final lubricant properties—including shear stability, HTHS viscosity and oxidation performance—must be validated in the finished formulation.

Selection Guidance

High VI OCP is recommended for lubricant manufacturers seeking:

• Maximum viscosity index improvement
• Multigrade engine oils requiring a high viscosity index
• Improved viscosity-temperature behavior
• Flexible formulation design
• Stable viscosity across wide operating temperatures
• Automotive and industrial lubricant applications

If the primary objective is maximum thickening efficiency, High Molecular Weight OCP may be more suitable. If the formulation requires exceptional resistance to permanent mechanical shear, High Shear Stable OCP should be considered.

Product selection should balance:

• Viscosity index improvement
• Thickening efficiency
• Shear stability
• Low-temperature performance
• Base oil compatibility
• Finished lubricant requirements

Frequently Asked Questions

What is High VI OCP?

High VI OCP is an olefin copolymer viscosity index improver developed to maximize the viscosity index of automotive and industrial lubricants.

What is its primary advantage?

Its primary advantage is maximizing viscosity index improvement, enabling lubricants to maintain more stable viscosity across a broad operating temperature range.

Is it suitable for modern engine oils?

Yes. It is suitable for PCMO, HDEO and other multigrade engine oils where high viscosity index is an important formulation objective.

Which base oils are compatible?

The product is compatible with Group I, Group II and Group III base oils. Compatibility with synthetic-rich formulations should be confirmed during development.

Does High VI OCP provide the highest shear stability?

Not necessarily. It is optimized for viscosity index improvement rather than maximum shear stability. Products specifically designed for shear stability may provide better viscosity retention under severe mechanical shear.

How is the recommended treat rate determined?

Treat rate depends on the base oil, target viscosity grade, desired viscosity index and overall formulation. Laboratory formulation trials are recommended.
