between 3.0 and 95.0 wt. % of a poly-ε-caprolactone polymer, wherein the poly-ε-caprolactone polymer has a number average molecular weight Mn of at least 50.000 g/mole and of maximum 90.000 g/mole, and

at least 5.0 wt. % of at least one second thermoplastic polymer material with a melting temperature of between 40 and 85° C., wherein the at least one second thermoplastic polymer material is one or more of a thermoplastic polyalkenamer or a thermoplastic linear polyurethane based on a poly-ε-caprolactone polyol or a polyester polyol;

wherein the poly-ε-caprolactone polymer and the second thermoplastic polymer material are cross-linked.

16. A method for producing an immobilization device, wherein a template according to claim 1 is heated to a temperature between 40 and 85° C., positioned on a body part that needs to be positioned, mobilized or immobilized, shaped to conform to the contours of the body part, and left to cool.
