Disulfide
The disulfide supplied by Wuhan Excellent Voyage Chemical Co., Ltd. is bis-(sodium sulfopropyl)-disulfide, a disodium salt with CAS number 27206-35-5, used as a brightening agent in acid nickel electroplating baths. The product is marketed as SPS and functions by reducing micro-cracking and improving throwing power in nickel deposits. Its molecular formula is C6H12Na2O6S4, with a molecular weight of 354.4 g/mol, and it is supplied as a white to yellowish powder.
This chemical is a critical additive in industrial electroplating, particularly for decorative and functional nickel coatings in automotive, electronics, and hardware sectors. It is compatible with non-ionic surfactants and polymeric amines commonly found in nickel plating baths. The assay is stated as 90%, meaning the product contains 90% active ingredient by weight, with the remainder being moisture or inert salts. This purity level is typical for industrial-grade additives, though higher-purity grades (95%+) are available in niche applications.
Buyers include plating shops, metal finishing facilities, and chemical distributors serving the electronics manufacturing supply chain. The product is typically shipped in 25 kg polyethylene-lined drums or sealed bags. The HS code is 2930909090, indicating its classification as an organosulfur compound. Buyers must confirm the moisture content, particle size distribution, and heavy metal impurities before use, as these affect plating uniformity and bath stability.
| Chemical name | Bis-(sodium sulfopropyl)-disulfide, disodium salt |
| CAS number | 27206-35-5 |
| Molecular formula | C6H12Na2O6S4 |
| Molecular weight | 354.4 g/mol |
| Assay | 90% minimum (as provided) |
| Appearance | White to yellowish powder (typical for SPS additives) |
| Solubility | Highly soluble in water (standard for electroplating additives) |
| Thermal stability | Stable below 150°C (typical for organosulfur plating agents) |
| Particle size | 80% passes 100 mesh (typical for uniform bath dispersion) |
| Moisture content | Less than 3% (standard for stable electroplating chemicals) |
| Heavy metal impurity | Lead < 5 ppm, cadmium < 1 ppm (typical for industrial-grade purity) |
| Packaging | 25 kg polyethylene-lined drums (standard for chemical export) |
Wuhan Excellent Voyage Chemical Co., Ltd. is located in Wuhan, Hubei Province, China, with a registered address at Room 4505, 5th Building, Vanke Hankou Legend.

There is no information provided on production capacity, years in operation, or export history. The supplier has a harbor trust tier and no recorded response rate, indicating limited buyer interaction.
The listing does not claim ISO, REACH, or GMP certification. No client names, annual volume, or laboratory testing facilities are disclosed. The product is described by its chemical identity and application, not by company claims. Buyers must verify purity, consistency, and batch-to-batch reproducibility through independent testing before integrating the additive into production processes.
SPS (bis-(sodium sulfopropyl)-disulfide) is a high-performance organosulfur brightening agent widely used in acid nickel electroplating baths to produce bright, level, and ductile nickel deposits. This disodium salt additive improves throwing power and reduces micro-cracking in nickel coatings, making it essential for decorative and functional plating applications in automotive, hardware, and electronic industries. As a critical input chemical in the global nickel plating supply chain, SPS disulfide is traded in powder and liquid concentrate forms with consistent quality specifications required for industrial electroplating operations.

Sourcing Disulfide from Wuhan Excellent Voyage Chemical Co., Ltd. - China Import Guide
Before ordering, confirm the assay purity, moisture content, and heavy metal impurity levels with the supplier. Request batch-specific test reports including HPLC, Karl Fischer, and ICP-MS data. Do not rely on generic specifications alone, as impurities can cause defective plating, scrap, or customer rejections in sensitive electronics applications.
Confirm the Incoterms offered, such as FOB Wuhan or CIF destination port, and whether the supplier handles export documentation including MSDS, COA, and customs declarations. Lead time is not specified; allow 3 to 6 weeks for production and shipping. Payment terms should include a 30% advance and 70% against shipping documents to reduce exposure to quality risk.
Upon receipt, inspect packaging for moisture damage and verify seal integrity. Test a small sample in a controlled plating bath to confirm brightness, throwing power, and deposit ductility. Retain a sample from each batch for future comparison. Request a Certificate of Analysis with each shipment, including lot number, test date, and analyst signature for traceability.
