The most important application in this field is the use of surfactants for the production of plastics and polymer dispersions by emulsion polymerisation. Surfactants have an important role in the emulsion polymerization processes; formation of micelles, stabilising the monomer droplets and the polymerized latex particles.
Unger UFAPOL range is composed of high quality anionic emulsifiers with specifications particularly accommodated for the high requirements of the emulsion polymerisation industry. The UFAPOL range is characterised by low levels of electrolyte and non-reacted material, very low levels of bi-products, consistent and well-defined raw material sources, light colour, pH and electrolyte tolerance and they are readily biodegradable.
Anionic emulsifiers like alkyl sulphates are distinguished by particularly good polymerisation behaviour and by the formation of fine-particle polymer dispersions. Alkyl ether sulphates are more soluble in water and are largely unaffected by water hardness. The growing preference for non-aromatic emulsifiers is leading increasingly to the replacement of alkyl phenol ether sulphates by alkyl ether sulphates.
