Résumé : |
Commonly used and state-of-the-art pilot fa-cilities to execute substantial polymer development in the field of linear polyester or gradual polymer modification are
- expensive, complicated, deeply involved in chemistry and analysis, step by step disappearing and uneconomical.
The polyester industry is matured and has changed to large capacity bulk production units. Development is mainly focused on capacity growth and cost saving at the expense of flexibility.
The polyester recycling industry is still vitally growing. Targets are to increase the product range and profitability. The material input properties mainly from fiber and bottle waste are quite limited. A broader range of polymer adaptation and modification is required to generate products of added value.
A suggested solution is polyester modification and material development by a simplified process existing of bse polymer modification by acidolysis, glycolysis and subsequent re-polycondensation.
Combination of conventional equipment and process simplification are offered as a pilot facility by the newly developed configuration consisting of Gneuss MRS vacuum extrusion and JUMP polycondensation with the option of reaction/residence time extension by adding a simple stirring autoclave.
The new pilot equipment is suitable for development, trial production and market introduction. |
