Description

What is Liquid Triphenyl Thiophosphate PSAIL 2320?

PSAIL 2320 is a specialized ashless organosulfur additive belonging to the chemical class of thiophosphate esters. Its specific composition is liquid triphenyl thiophosphate (CAS 192268-65-8). This molecular structure strategically incorporates both phosphorus and sulfur, making it a highly effective dual-functional agent. It offers extreme pressure (EP) and anti-wear properties, and is free of metals (i.e. "ashless"), thereby avoiding the catalytic decomposition of lubricants and minimizing the formation of deposits. It can be used as a substitute for IRGALUBE 232.

Features of Liquid Triphenyl Thiophosphate PSAIL 2320:

Advanced Dual-Active Chemistry: Combines phosphorus (for anti-wear) and sulfur (for extreme pressure) in a single, balanced molecule.

Superior Material Compatibility: Non-corrosive to yellow metals (copper, brass) and ferrous metals, a critical advantage over many traditional sulfur-based EP agents.

Excellent Solubility Profile: A liquid product with outstanding solubility across a broad spectrum of base oils, including mineral oils, polyalphaolefins (PAOs), and synthetic esters.

Enhanced Stability: Exhibits good hydrolysis stability, resisting breakdown in the presence of moisture, which contributes to longer fluid life.

Ashless and Clean: Leaves no metallic ash or solid residues upon thermal decomposition, helping to keep systems clean and maintain oil filterability.

Easy Handling: Supplied as a low-viscosity liquid, it is easy to pump, meter, and blend into formulations at room temperature.

Functions of Liquid Triphenyl Thiophosphate PSAIL 2320:

Extreme Pressure (EP) Protection: The sulfur component activates under conditions of high load and shock to form a protective iron sulfide film on metal surfaces, preventing welding, scuffing, and seizure.

Anti-Wear (AW) Performance: The phosphorus component forms a protective boundary film (e.g., iron phosphates) under moderate loads and temperatures, minimizing surface wear and friction.

Friction Reduction: Helps lower the coefficient of friction in the boundary lubrication regime, contributing to improved efficiency and energy savings.

Oxidation Stability Support: Its stable nature helps protect the lubricant from premature oxidative degradation, indirectly extending oil drain intervals.

System Cleanliness: Its ashless nature and non-corrosive properties help prevent sludge, varnish, and corrosion-related deposits, protecting system components.

Applications of Liquid Triphenyl Thiophosphate PSAIL 2320:

Metalworking Fluids (MWF): A premier choice for neat cutting oils, grinding fluids, and drawing oils, especially for severe operations on ferrous metals where copper corrosion is a concern (e.g., machining parts with brass fittings).

Engine Oils: Used as an effective secondary anti-wear/EP additive in certain heavy-duty diesel engine oils and specialized formulations to enhance valve train and gear protection.

Industrial Oils:

Hydraulic Oils: For high-pressure systems requiring enhanced anti-wear protection (exceeding standard zinc dialkyldithiophosphate levels).

Air Compressor Oils: Protects vital components in rotary screw and reciprocating compressors from wear under high-pressure conditions.

Gear Oils & Circulation Oils: Provides supplemental EP/AW performance.

Greases: Imparts high-load carrying capacity and wear protection to greases used in heavy-duty bearings, joints, and industrial applications.

General Industrial Lubricants: For any application requiring a balanced, ashless, and non-corrosive EP/AW additive.

Recommended Dosage: The typical treat rate is 0.5% to 2.0% in finished formulations for engine oils, industrial oils, and greases. Specific dosage should be optimized based on the base oil, other additive components, and the final performance requirements.
