US-based supplier of closure systems for rigid packaging W R Grace group company Grace Davison Materials and Packaging has introduced a rotational rheometer from Malvern Instruments to enhance the development of new food-grade and industrial sealants.
The sealant improves performance of the package, from food and beverage cans through to 55-gallon drums that require a hermetic seal.
The Malvern rheometer is cost-effective, reliable and easy-to-use choice for steady shear and oscillatory testing throughout the product development cycle, reports Azomaterials.
Grace Davison Senior R&D Chemist Salvador Crespo said that the 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.
The rheometer is easy to clean, and simple to switch between different test types for wet or dry samples, aqueous or solvent based systems.
The sealants from Grace Davison support both solvent and water-based cans and provide flexibility to develop products within both technology platforms.
