LANXESS offers a variety of Addovate^® multi-purpose silicon-free surfactants which can be used in the production of ester-based flexible and rigid foams as well as cellular hot cast elastomers, e. g. based on NDI-technology.

Addovate^® surfactants act mainly as emulisifiers and foam stabilizers:

• enable a proper emulsification / dispersion of formulation components, resulting in a homogeneous foaming mixture.
• stabilize the foam structure during rising and prevent foam from collapsing
• inhibit coalescence of gas bubbles, control cell size and structure, regulate cell opening and foam porosity (airflow)
  
  Addovate^® surfactants are silicon-free and can thus be used in critical applications, where use of silicon-based products is undesirable.
  This can be especially advantageous in clickable foams due to improved die-cutability.
  
  Products made with Addovate^® surfactants are used in a wide range of applications, such as:

• technical and textile foams
• automotive moulded foams
• auxiliary dampeners
• buffers for construction industry and many others
