BASF launches world’s first TPA for sausage artificial casings

BASF is launching Ultramid H33 L, the world’s first thermoplastic polyamide with a high water permeability. Ultramid H33 L features a unique combination of strength and water permeability that made for artificial casings in which sausages can be smoked and then dried.

BASF launches Ultramid H33 L which is ideal for producing artificial casings for smoked sausages.

The artificial casings for sausages have so far been made of collagen or cellulose. As the new polyamide can be used to produce artificial casings with significantly thinner walls due to its strength, it is an attractive alternative to these materials.

Due to the hydrophilic properties of Ultramid H, the desired smoke aromas pass through the artificial casing made of pure polyamide into the sausage products during the smoking process. The high water permeability allows subsequent drying directly in the casing.

“Ultramid H opens up new fields of application for thermoplastic polyamides that were previously beyond technical capabilities and is unique among thermoplastics. It can be processed like any other polyamide, enabling our customers to incorporate Ultramid H into their production processes without making any adjustments,” explained Dr. Rolf Minkwitz, who is responsible for polyamide product development at BASF.

Ultramid H will be presented for the first time at K 2025. Experts will be available at the stand to answer questions about the product’s properties and will discuss initial application experiences with the customer PODANFOL S. A., an artificial sausage casing supplier in Poland, on October 9 at 3 pm.
