| Résumé : |
The properties of polyvinyl chloride are adjusted using plasticizers for many applications. Phthalate-free plasticizers can keep pace here with conventional versions containing phthalates in many technical fields. This article demonstrates that based on a comparative study. |

- Hardness and volatility
- Fogging behavior and viscosity
- Polymerization and processing
- FIGURES : 1. The comparison of the shore A hardness shows that PETV is most efficient compared to the other test candidates - 2. Volatility of the softeners. Since the additives have a significant influence on the characteristics of PVC, their amount should remain constant during the entire lifespan of the material - 3. Fogging test according to DIN 75201-A on an automotive film (700g/m2, 75 phr). The reflectometer value was determined on a glass plate. Here the phthalate-free plasticizer trioctyl trimellitate (TOTM) was tested in addition - 4. The viscosity comparison shows that the softener DINCH keeps the plastisol constant over a long period of time, and is therefore well suited for delayed processing - 5. The rheology of the three test candidates shows that plastisol formulation with PETV proceeds more quickly and at lower temperatures - 6. The absorption diagram shows the time in which phthalate-free plasticizers are absorbed in suspension PVC
- TABLES : 1. The initial formulation of the plastisol in which each of the three plasticizers was tested - 2. Processing temperature and time in which the plasticized PVC respectively reach the desired degree of elongation |
