Polyether or polyester - What is the difference?

What is the difference between acoustic foams based on polyether and foams based on polyester?

Polyether acoustic foams have the following characteristics:
  • Soft grip
  • Flexible and elastic
  • Fine, porous structure
Polyester acoustic foams have those characteristics:
  • Stable grip
  • Coarsely, open-pore structure
  • Higher absorption rate than polyether products
  • Very steady-going pore structure, compared to polyether-acoustic foams
  • Homogeneous pore structure

aixFOAM acoustic foams  on polyester-basis have a special acoustically modified pore structure. Our decades of experience make the small but significant difference between our products and other foams which are often overhasty declared as “acoustic foams”.

 

 

Note: If you want to combine polyether- and polyester products, please consider that the products have slightly different colours (Polyester usually is a bit darker).

The production of aixFOAM acoustic foam is a highly complex foaming-procedure. All these foams consist of polyurethane with different pore-size (micro porous, heterogeneous structure). Since the pores have different sizes and shapes, colour variations can occur due to light reflections (based on the viewing angle).
