The present invention relates to a method of manufacturing a foamed thermoplastic elastomer particles gaseous medium captures, said method following steps a) impregnation step,
Here, the gaseous medium has an impregnation temperature T
a, the absolute pressure of the gaseous medium is higher than the ambient pressure,
Blowing agent is dissolved in the thermoplastic elastomer particles,
b) foaming process,
Here, the thermoplastic elastomer particles, in a first foaming temperature T
b, exposed to reduced pressure and foaming,
c) optionally, the fusion process,
Here, the foamed thermoplastic elastomer particles, a fusion temperature T
c, are fused together to form at least one molded part,
It includes,
It said thermoplastic elastomer particles, amorphous thermoplastic elastomers, partially crystalline thermoplastic elastomers, or consist of a mixture thereof, the impregnation temperature T
a, the first foaming temperature T
b and the fusion temperature T
c is, Depending on the nature of the thermoplastic elastomer, about it,
i. When the thermoplastic elastomer is amorphous, the impregnation temperature T
a, the first foaming temperature T
b and the fusion temperature T
c is higher than the first limit temperature
T G-40, the first limit temperature T
G -40, DIN EN ISO of the non-impregnated thermoplastic elastomer particles 11357-2: 2013-09 40 ℃ lower than the glass transition temperature
T G by,
