1,3,2-Dioxaphosphorinane, 2,2′-oxybis[5,5-dimethyl-, 2,2′-disulfide

1,3,2-Dioxaphosphorinane, 2,2′-oxybis[5,5-dimethyl-, 2,2′-disulfide, also known by CAS 4090-51-1, is a specialized phosphorus-sulfur compound. It is widely utilized as an antioxidant and extreme-pressure additive in various industrial formulations.

This chemical functions by providing both antioxidant stabilization and lubrication performance in demanding processing environments. It is particularly effective in systems requiring high thermal stability and chemical resistance.

In lubricant and metalworking fluid formulations, it acts as an extreme-pressure and anti-wear additive. It protects metal surfaces under high-load conditions, preventing surface damage and reducing friction during heavy industrial operations.

Petroleum and synthetic base oil blenders incorporate this compound to extend fluid service life. By inhibiting oxidative degradation, it ensures that lubricants maintain their viscosity and performance characteristics over longer periods.

In plastics and polymer processing, it functions as a processing stabilizer. It helps prevent thermal oxidation during compounding and extrusion, ensuring the structural integrity of the final polymer product is maintained.

Its dual phosphorus-sulfur functionality makes it relevant for gear oils, hydraulic fluids, and grease formulations. It is ideal for applications where combined antioxidant and extreme-pressure performance is strictly required.

This product is typically supplied as a solid powder or crystalline material for easy handling. It is available in technical grade, which is perfectly suited to industrial lubricant and polymer additive applications.

Packaging is generally offered in kilogram-scale bags or drums depending on specific volume requirements. Our logistics team ensures that all shipments meet the necessary safety standards for industrial chemical distribution.
