Abstract: A bead foam is made of thermoplastic polyurethane, a styrene polymer, and an impact modifier. Moldings can be produced from the bead foam and processes for the production of the bead foams and moldings can be utilized. The moldings can be used for shoe intermediate soles, shoe insoles, shoe combisoles, cushioning elements for shoes, bicycle saddles, bicycle tires, damping elements, cushioning, mattresses, underlays, grips, protective films, in components in the automobile-interior sector or automobile-exterior sector, balls and sports equipment, or as floorcovering.

Abstract: Foam particles that have a bulk density below 300 kg/m3 and are based on polyamides, including 85% to 100% by weight of at least one copolyamide obtainable by polymerizing the following components:



(A) 15% to 84% by weight of at least one lactam,
(B) 16% to 85% by weight of a monomer mixture (M) including the following components:

(B1) at least one C32-C40 dimer acid and
(B2) at least one C4-C12 diamine,
wherein the monomer mixture (M) includes in the range from 45 to 55 mol % of component (B1) and in the range from 45 to 55 mol % of component (B2), based on the total molar amount of the monomer mixture (M), and the sum total of the components of (A) and (B) is 100% by weight, and processes for production thereof.

Abstract: Foamed pellets contain a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition (IC), containing at least one aliphatic diisocyanate having a number-average molecular weight of less than 200 g/mol, at least one chain extender (CE1), and a polyol composition (PC). A process can be used for the production of such foamed pellets. The foamed pellets can be used for the production of a molded body.
