1. What is polyurethane?
Polyurethane, also referred to as PU is a synthetic, foamed material that is made up of two components: polyol and isocyanate. They are mixed at a temperature of approximately 50°C in order to eventually form a polymer with air bubbles.
The combination of both a soft and a hard component forms the basis for PU's double properties: flexible as well as strong and durable.
2. How are Bekina boots made?
Polyurethane boots are made through injection on a carousel. A conical screw injects the material into a mould.
The production of polyurethane boots is quite complex and delicate. In order to obtain a foamed polyurethane, several chemical reactions occur at the same time a few seconds apart. Several factors determine the success of the chemical reaction:
- the right choice of components
- the correct dose and temperature
- the carousel's rotation speed
- ...
That is why Bekina is proud to be one of the few companies in the world to have mastered this high-tech process.
