Foaming polyurethane systems

Main category >Polyurethane resins >Foaming polyurethane systems

As with other crosslinking resin systems, foaming polyurethane systems undergo product formation and formation simultaneously. This process is typical for the production of various polyurethane foams, both of extremely variable hardness and in their appearance.

They can be grouped according to several aspects:

  • Chemical structure
  • Hardness
  • Reactivity
  • Manufacturing technology
  • Area of ​​application

Their foaming can be characterized by the following parameters:

Mixing time: time for mixing components
Start time / cream time: time from the start of mixing to the increase in viscosity of the reaction mixture
Curing time: time from the start of mixing to the cessation of flowability
Rise time: time from the start of mixing to the end of the foam rise
Adhesion (tack) time: time from the start of mixing to the cessation of tack

Our range includes hard, flexible and integral foams, foam systems for both machine and manual use.

 

They fall into the following subcategories:

  • Block foams, blocks (closed cell)
  • Molded foams (open cell, closed cell)
  • Molded foams (closed cell)
  • Sprayed foams (open cell, closed cell)
