BASF has introduced Ultramid® H33 L, the world’s first thermoplastic polyamide with high water permeability. This breakthrough combines mechanical strength with controlled permeability, opening up new applications previously beyond the reach of thermoplastic materials.
Transforming Sausage Casing Production
BASF designed the innovative polyamide for artificial casings in sausage production. Traditionally, manufacturers used collagen or cellulose for such casings. With Ultramid H, they can now produce significantly thinner walls without compromising strength, making it an attractive and efficient alternative.
Its hydrophilic properties allow smoke aromas to penetrate seamlessly through the casing during the smoking process, while its high water permeability enables direct drying of sausages inside the casing—streamlining the production process.
Easy Integration into Existing Processes
“Ultramid H opens up new fields of application for thermoplastic polyamides that once exceeded technical capabilities and stands unique among thermoplastics,” said Dr. Rolf Minkwitz, BASF’s Polyamide Product Development Lead. He emphasized that customers can process Ultramid H like any other polyamide and integrate it into existing production lines without making modifications.
Setting New Standards in Polyamide Research
With the launch of Ultramid® H33 L, BASF is setting new benchmarks in polyamide research and application development. As per company press release, by combining high strength with permeability, the material not only expands the functionality of thermoplastics but also offers food manufacturers a sustainable, efficient, and high-performance solution.
