PPS

Excellent Thermal and Chemical Stability
PPS demonstrates strong resistance to heat and chemical environments, maintaining stable performance during demanding electroplating processes and ensuring reliable long-term operation.

Outstanding Mechanical Performance
With excellent mechanical strength and structural stability, PPS contributes to the formation of durable and high-quality nickel plating layers with improved surface properties.

High Purity and Efficient Bath Performance
As a highly effective plating additive, PPS introduces minimal impurities into the electrolyte system, helping maintain plating solution stability, extend bath life, and improve process consistency.

Superior Brightening and Leveling Effect
PPS functions as an efficient secondary brightener and leveling agent. When combined with saccharin, acetylene compounds, and wetting agents, it helps produce nickel coatings with excellent brightness, smoothness, uniformity, and flexibility, even in non-circulating electrolyte systems.

Product Description

PPS (CAS No. 15471-17-7) is an important intermediate used in the preparation of nickel electroplating brighteners. It features excellent thermal stability, chemical resistance, and mechanical properties, making it a valuable additive in advanced plating formulations.

Due to its high purity and effective brightening performance, PPS can enhance the appearance and quality of nickel coatings without introducing undesirable impurities or excessive salts into the plating bath. It also helps improve coating leveling, surface gloss, and ductility while maintaining stable electrolyte performance.

In practical electroplating applications, PPS is commonly used together with saccharin, acetylene-based compounds, and other auxiliary additives to achieve highly bright, smooth, and uniform nickel deposits. It is suitable for both conventional and low-flow electrolyte systems, providing reliable performance for precision plating processes.
