Germany, Sept. 9 -- With the launch of Ultramid(R) H33 L, BASF is introducing the world's first thermoplastic polyamide with a high water permeability to the market. The unique combination of strength and water permeability makes Ultramid H an innovative material for artificial casings in which sausages can be smoked and then dried.Such casings have so far been made of collagen or cellulose, for instance. 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. Thanks 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 ...
