Malvern rheometer helps Materials and Packaging company bring new food-grade sealants to market

Malvern rheometer

Rotational Rheometer to help accelerate the development of new food-grade and industrial sealants

Grazia Materiali Davison e Packaging Technologies, un gruppo di prodotti di WR Grace & Co., un fornitore leader di state-of-the-art sistemi di chiusura per imballaggi rigidi, utilizza un reometro rotazionale da Malvern Instruments per accelerare lo sviluppo di nuovi alimentare e Sigillanti industriali. La reologia dei sigillanti è un attributo critico per l'attuazione del pacchetto, da alimenti e bevande lattine sui tamburi 55 galloni che richiedono una tenuta ermetica. Reometro Malvern ha dimostrato di essere una scelta conveniente, affidabile e facile da usare per taglio costante e test oscillatorio tutto il ciclo di sviluppo.

“Using the rheometer shortens research times – a major gain,” remarks Salvador Crespo, Senior R&D Chemist, Grace Davison. “The bench top Malvern data provides predictive modelling of liquid and dry flow properties, which are used as a screen to advance new developments into the pilot testing stage. We can get very close to an optimal formulation through small scale rheological testing. The rheometer is easy to clean, and it’s simple to switch between different test types for wet or dry samples, aqueous or solvent based systems. Malvern has given us great support to optimise our testing procedures. We are developing a broad line of products to satisfy our customers’ needs with state-of-the-art research equipment”.

Grace Davison uniquely supplies the industry with both solvent- and water-based can sealants. The Malvern equipment provides flexibility to develop products within both technology platforms. Continuous innovation enables Grace Davison to bring new high performance products to market.

The rheometer combines steady shear and oscillatory testing capability with excellent temperature control. Measuring viscosity as a function of shear rate, and of temperature, enables Grace Davison to optimise raw material choice and formulation composition to reach performance targets. Particularly challenging is the development of stable, highly-filled, high-solids dispersions. Here degradation studies and analysis of the visco-elastic response as a function of time provide the information to formulate products that maintain stable performance under simulated commercial handling conditions.
