Ester foams

Ester foams


Polyester foams have a more uniform cell structure than polyether foams and are conditionally resistant to oil and grease. They sport many applications, among other as sound absorbers, or where resistance to oil is needed.

Customer benefits

  • very soft and springy
  • good resistance to hydrolysis 
  • good restoring force
  • sound absorbing 
  • physiologically harmless
  • temperature resistant from – 30 to + 100 
  • conditionally resistant to chemicals and ageing 

Field of application

This polyurethane foam belongs to the polyester class of foams. Its excellent working properties render it useful in many fields of application.

Especially where density and optimal foam combinations are demanded, such as suitably shaped spacers, or all types of dampening, acoustic decoupling and sealing.
