  • Publication number: 20250002718
    Abstract: A foamed article is synthesized from a blend of homogenously mixed polyether amide and thermoplastic polyurethane. A method for preparing the foamed article includes providing a polyether block amide and a thermoplastic polyurethane, compounding the polyether block amide and the thermoplastic polyurethane and forming a blend, shaping the blend and forming a preform, and foaming the preform and obtaining the foamed article.

  • Publication number: 20240084086
    Abstract: A polymeric blend contains a polyether block amide and a thermoplastic polymer, where the polyether block amide is based on a subunit 1 and a subunit 2. Subunit 1 is composed of at least one linear aliphatic diamine containing 5 to 15 carbon atoms and at least one linear aliphatic dicarboxylic acid containing 6 to 16 carbon atoms. Subunit 2 is composed of at least one polyether diol containing at least 3 carbon atoms per ether oxygen and primary OH groups at the chain ends. The sum total of the carbon atoms from diamine and dicarboxylic acid is an odd number and is 19 or 21 carbon atoms. The number-average molar mass of the subunit 2 is 200 to 900 g/mol. The thermoplastic polymer is selected from an ethylene/vinylene acetate, a thermoplastic polyester elastomer, a polyolefin elastomer, thermoplastic polyurethane, or any mixture thereof.

  • Publication number: 20240034855
    Abstract: Nanoparticle compositions contain a graphene-based material. A preparation process involves providing several components and milling a mixture. The nanoparticle compositions can be used as a lubricant additive to improve tribological performance, in particular to improve anti-friction and anti-wear performance on metal parts. A corresponding lubricant composition contains these nanoparticle compositions.
