The special feature of this type of plastic is that, in contrast to thermoplastics, it remains dimensionally stable when the temperature rises and thus can not be deformed. In the production of polyurethane products, the polymer-producing polymer reaction takes place in a form designed for it, which at the same time determines the product shape and properties.

There are three basic ways to recycle polyurethane foam, where only a chemical process can produce a product that can be traced back to the original application without sacrificing quality. Below we present the most important recycling methods:

The chemical recycling of polyurethane is to break the long polymer molecule into shorter segments by a chemical reaction and attach to each of them reactive hydroxyl OH groups. This creates a special type of polyol that can be incorporated into a new polymer chain.

Reusing precious raw materials such as PET gives companies the opportunity to fully exploit the financial investment made in these plastics.
The synthesis of polyester polyols for the production of polyurethane plastics is very widespread and the process is numerous described in the literature. It offers a great advantage over the process used to make polyether polyols.
