The latest results of the Placard project presented at the EuPC premises on 8 and 9 July show that very good progress is being made. The project aims at producing a new bio-based plasticizer for soft PVC, with a focus on applications in construction.

The technology involves the chemical modification of cardanol, an industrial grade yellow oil obtained by vacuum distillation of cashew nut shell liquid. By using a by-product such as cashew nut shells, the Placard plasticizer is not in competition with food resources.

Production of the Placard plasticizer was carried out at Serichim premises on a pilot scale; tests were conducted by Università di Salento that compared properties from different high/low molecular weight phthalates and non-phthalates plasticizers. Placard results showed better plasticizing efficiency than DEHP and DOTP enabling raw material saving. Processability and an energy cost reduction were other parameters that demonstrated better performance compared to selected commercial plasticisers. Remaining tested parameters were comparable with other selected plasticisers and showed good stability of properties over time.

Additional results, such as ability to facilitate recycling, will be further investigated and quantified. They will be presented in internal meetings and at targeted conferences by EuPC that is in charge of the dissemination activities as well as by Kommi, the project leader.(KL)
