Lanphos PS10

Product Category: Anionics

Quick Links

A powerful emulsifier that can be used across a wide range of polymer systems and more importantly is used as a primary emulsifier without the need for a secondary surfactant to stabilise the system. As a versatile emulsifier, this is the first choice for any formulator. As well as providing extremely small particle sizes it has an in-built stabiliser system to prevent re-agglomeration of polymer particles.
