Polypropylene Glycol Frother (PPG Type)
CAS Number: 25322-69-4
Polypropylene Glycol (PPG) frothers are polymeric surfactants that produce persistent, fine-bubble froths suitable for flotation of fine particles and slimes. Their molecular weight and degree of propoxylation can be tailored to control froth stability, bubble size, and selectivity for specific ore applications. PPG frothers are particularly effective in fine coal flotation and in circuits where fine-particle recovery is a priority.
