Molding compound containing polyether block amide (PEBA)

A molding compound contains polyether block amide (PEBA) based on a subunit 1 made of at least one linear aliphatic diamine having 5 to 15 C atoms and at least one linear aliphatic or aromatic dicarboxylic acid having 6 to 16 C atoms. The PEBA also contains a subunit 2 made of at least one polyether...

Beschreibung
Zusammenfassung:	A molding compound contains polyether block amide (PEBA) based on a subunit 1 made of at least one linear aliphatic diamine having 5 to 15 C atoms and at least one linear aliphatic or aromatic dicarboxylic acid having 6 to 16 C atoms. The PEBA also contains a subunit 2 made of at least one polyether diol having at least 3 C atoms per ether oxygen and primary OH groups at the chain ends. The sum of the C atoms of diamine and dicarboxylic acid is odd and is 19 or 21, and the number-average molar mass of the subunit 2 is 200 to 900 g/mol. A molded object can be created from the molding compound, which can be a molded part, a film, a bristle, a fiber, or a foam.
