Ultramid H marries polyamide strength with water permeability for sausage casings

BASF is bringing the first thermoplastic polyamide with a high water permeability to the market with the introduction of Ultramid H33 L. Ultramid H is a novel material for artificial casings that allow sausages to be smoked and then dried because of its strength and water permeability.

Collagen or cellulose have been used to make such casings. The new polyamide is a substitute for traditional materials since it can be utilised to create artificial casings with thinner walls because of its strength.

Ultramid H’s hydrophilic qualities allow the intended smoke scents to permeate the banger goods’ artificial, pure polyamide casing and enter during the smoking process. Direct drying within the casing is made possible by the high water permeability.

“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.

With the development of this innovative material, BASF is setting new standards for both polyamide research and its applications and will present Ultramid H for the first time at the world’s largest plastics trade fair “K”, which will take place in Düsseldorf from October 8 to 15.

Experts will be available at the BASF stand in hall 5, C21/D21 to answer questions about the product’s properties and will discuss initial application experiences with the customer PODANFOL S. A. on October 9 at 3 pm.
