Viscoplex 14-520 Jun 2026

The low SSI of 15 indicates that Viscoplex 14-520 loses very little thickening power even under extreme mechanical shear. This is a standout feature compared to many OCP (olefin copolymer) modifiers which may have SSIs of 30-50.

Viscoplex 14-520 is frequently used in industrial and automotive lubricant formulations where foam control is vital, including: and circulating oils. Compressor Oils . Automotive Transmission Fluids . Biodegradable Fluids and engine oils.

Viscoplex 14-520 belongs to the polymethacrylate (PMA) family. Specifically, it is a . The "non-dispersant" designation is critical: it means the additive does not contain polar groups designed to suspend sludge or contaminants. This specialization allows Viscoplex 14-520 to focus exclusively on viscosity-temperature relationships without altering the detergency or dispersancy profile of the final lubricant.

VISCOPLEX® 14-520 is a high-performance additive developed by Evonik Industries primarily designed for foam control air release

Specialized for use in biodegradable fluids where traditional additives may not be compatible. If you'd like, let me know: The low SSI of 15 indicates that Viscoplex

Adding Viscoplex 14-520 to a lubricant blend is straightforward, but best practices should be followed:

| Component | Percentage | Function | |-----------|------------|----------| | API Group II base oil (viscosity 12 cSt @ 40°C) | 88.0% | Base fluid | | Viscoplex 14-520 | 7.5% | Viscosity index improver | | Anti-wear additive (ZDDP type) | 1.0% | Wear protection | | Antioxidant package | 0.5% | Oxidation resistance | | Corrosion inhibitor | 0.5% | Rust prevention | | Demulsifier | 0.1% | Water separation | | Antifoam agent | 0.1% | Foam control | Compressor Oils

For technical formulators, specifications are non-negotiable. Here are the typical properties of Viscoplex 14-520 as delivered:

Viscoplex 14-520 is a high-molecular-weight, non-dispersant polymethacrylate (PMA) viscosity index improver. It is designed specifically for mineral oils and synthetic base stocks used in hydraulic fluids, gear oils, compressor oils, and specialized industrial lubricants. Unlike many standard viscosity modifiers, Viscoplex 14-520 is engineered to provide exceptional thickening efficiency with minimal impact on the oil's shear stability index (SSI).
