Import Alkylated Triphenyl Phosphorothionate — Buy in Bulk from Supplier in China

Alkylated Triphenyl Phosphorothionate, marketed by Hangzhou Bais Chemical Technology under the trade name Runlube 211, is an extreme pressure and antiwear additive for lubricant systems. The product carries CAS number 126019-82-7 and contains 4.3% phosphorus and 4.4% sulphur by elemental analysis. Supplied as a liquid from the company's Hangzhou facility in Zhejiang Province, China, this phosphorothionate is positioned as a functional equivalent to Irgalube 211 with handling advantages over solid triphenyl phosphorothionate (TPPT).

The molecular structure combines an alkylated triphenyl backbone with phosphorothionate functionality, where the P=S bond provides sulphur-derived extreme pressure performance and the phosphorus contributes antiwear film formation on ferrous surfaces. The liquid physical form at ambient temperature distinguishes it from crystalline TPPT, simplifying blending operations and eliminating dissolution or melting steps in lubricant manufacturing. Typical base oils compatible with this additive include Group I, II, and III mineral oils, polyalphaolefins, and certain ester basestocks, though compatibility with specific additive packages should be verified through bench testing before commercial formulation.

Primary applications encompass metalworking fluids, industrial and automotive lubricant oils, lubricating greases, and fuel lubricity enhancement. Buyers include lubricant blenders, metalworking fluid compounders, and additive package manufacturers seeking phosphorus-sulphur synergy without handling solid raw materials. The 4.3% phosphorus content places this material within typical treat rate ranges for medium to high-performance lubricant formulations, though exact treat rates depend on base oil type, application severity, and performance targets such as FZG fail load stage or four-ball weld load.

Hangzhou Bais Chemical Technology Co., Ltd is located at No.118 Dongganglu Road, Yuhang District, Hangzhou, 311100, Zhejiang Province, China. The company holds a harbor trust tier on the platform, though its displayed response rate is 0.00% with zero average response hours, indicating that direct engagement through platform messaging may be unreliable. Prospective buyers should seek alternative contact methods such as the company's direct telephone, email, or trade show presence to ensure effective communication.

The company markets chemical products under the Runlube brand, with Runlube 211 being the specific alkylated triphenyl phosphorothionate grade positioned against the established Irgalube 211 benchmark. No information is provided regarding year of establishment, manufacturing site certifications, production capacity, number of employees, annual revenue, or named client references. Buyers should conduct due diligence on manufacturing quality systems, regulatory compliance capabilities, and supply chain resilience before committing to volume orders.
