PPS CAS# 15471-17-7
Excellent Thermal and Chemical Stability: PPS maintains stable performance under high temperatures and harsh chemical environments, ensuring reliable use in demanding plating processes.
High Mechanical Strength: It offers strong mechanical properties, contributing to the durability and integrity of the resulting nickel plating layer.
High Purity and Long Service Life: As a brightener, PPS introduces no harmful impurities or salts into the plating bath, extending electrolyte life and maintaining consistent performance.
Superior Brightening and Leveling Performance: When used with saccharin and other additives, PPS produces a highly bright, smooth, and stretchable nickel coating, suitable even for non-flowing electrolytes.
PPS exhibits good thermal stability and chemical stability, as well as excellent mechanical strength. However, its low molecular weight makes it prone to disproportionation and cross-linking reactions.
PPS is a starting material for preparing brighteners; it is a highly efficient brightener (secondary brightener) and leveling agent. Due to its high purity, it does not introduce harmful impurities or salts into the plating solution, has a long service life, and does not cause stretching problems. It is typically used in combination with saccharin, one or more acetylene compounds, and wetting agents. This process results in a particularly bright, level, and stretchable nickel plating layer. It is also suitable for applications where the electrolyte is not flowing.
