For emulsion polymer applications, it’s crucial to select an emulsifier with the right properties—water solubility, molecular charge and critical micelle concentration (CMC) are all important factors to consider.
Innospec offer a broad range of additives to choose from when designing an emulsion polymer formulation. The breadth of choice allows formulators to have control over every step of the process, from initial droplet size to the stability of the final resin.
In addition to the functionalities which traditionally feature in emulsion polymers, Innospec’s portfolio also features:
- Sulfates: Widely used emulsifiers, characterised by good particle size control and excellent regulatory compliance.
- Ether sulfates: APE-free emulsifiers with excellent particle size control, with the ability to make emulsions with a very small particle size.
- Sulfonates: Emulsifiers which are highly suited for use with hydrophobic monomers. Excellent thermal and hydrolytic stability, even at extreme pH conditions.
- Sulfosuccinates: Primary and secondary emulsifiers used for both emulsion & suspension polymerisation. Exceptional wetting agents.
- Phosphate esters: Excellent emulsifiers for polymerisation, imparting low water sensitivity and excellent electrolyte tolerance.
- Specialty products: A selection of solvents, monomers, dispersants and chelating agents which show strength in their respective applications.
