PU PROCESS

Coagulated Polyurethane vs Reactive Polyurethane

1 · Coagulated PU

- Stage 1. Coagulating Line

- Stage 2. Casting Line

On a molecular level, coagulated PU has great levels of carbon groups and ester. These compounds are very unstable with humidity and heat due to the high moisture absorption rate of the lower cells. This causes structural hydrolysis resulting in the peeling on the surface.

There is a need of solvents in the production of this material.

The machinery is long and complex resulting in unstable materials.

2 · Reactive Poliurethane: High System

Using high quality PU (polyether) which has a much stronger molecular structure that does not allow for carbodiimide hydration thus avoiding prior problems. We achieve this through the introdu ction of reactive polyurethane (A+B, polyol+isocianite) in the production, giving us a high resistance product with 10 year antihydrolysis resistance.

This is a short and fast production process at low temperatures and without solvents, that allows for different types of finishing such as FR, anti-bacterial, easy clean, etc.
