Flotation frothers
Our POLYFROTH® frother series offers the full spectrum of frother strengths and properties (e.g., selectivity, water solubility, diffusion kinetics) required in mineral and coal flotation applications. Lower VOC levels and reduced flammability are also provided when compared to common alcohol-based frothers. Solutions include the POLYFROTH® 50 frother series, which is recognized as strong; the POLYFROTH® 30 frother series (intermediate); and the POLYFROTH® 20 frother series, which is moderate. Our POLYFROTH® 10 series is the weakest and most selective of the range. 
 
 

POLYFROTH® H15

Generates dry, loose and brittle froths of low to moderate stability.

POLYFROTH® H20

Hydrophobic and produces an open froth structure with fine bubbles and loose, brittle froth. Demonstrates fast flotation kinetics and low froth persistence.

POLYFROTH® W22

Generates fine bubbles of uniform froth structure with good water drainage characteristics. Similar froth and solution characteristics to methyl isobutyl carbinol (MIBC) in some applications. Fast kinetics and offers controlled froth persistence.

POLYFROTH® H23

Provides a close match to the bubble and froth characteristics of MIBC. Highly selective, demonstrates fast flotation kinetics and low froth persistence.

POLYFROTH® H27

Hydrophobic and produces a drier froth with well-defined froth structure, wide bubble size distribution and good froth stability and kinetics.

POLYFROTH® H30

Fine, freely draining froth of an intermediate strength. Offers good selectivity, efficiency and kinetics.

POLYFROTH® W31

Fine, freely draining froth of low to intermediate strength. Offers good selectivity and moderate kinetics.

POLYFROTH® W34

Low to moderate hydrophobicity, producing mobile, fluid froths with well-defined froth structure and bubble size distribution.

POLYFROTH® W53

High froth strength and fast flotation kinetics, whilst remaining fully water-soluble. Produces tight, strong bubbles of good mobility.

POLYFROTH® W55

Stronger frother with moderate hydrophobicity and improved water retention. Demonstrates strong froth generation and froth persistence, producing well-defined bubbles and uniform froth generation down-the-bank.

POLYFROTH® H57

Hydrophobic and produces a strong, drier froth characterized by a fine structure and mobility. Demonstrates fast flotation kinetics.
