Glycol Ether Frother (DF-250 Analogue)
Glycol ether frothers of the DF-250 type are propylene glycol-based poly-ether frothers producing a narrow, controllable bubble size distribution and moderate froth persistence. They are widely employed in copper, molybdenum, and coal flotation as a substitute for brand-name frothers, offering comparable performance at competitive cost. These reagents provide consistent bubble nucleation and froth transport characteristics essential for reliable metallurgical performance.
Technical Specifications
