thermoplastic polyurethane(TPU)or polyurethane elastomers (PUEs)

Degradation of polyurethane elastomers (PUEs) and their stabilizers

Thermal oxygen degradation of polyurethane elastomers (PUEs) and its stabilizers Thermo-oxidative degradation is a free radical chain process initiated by atmospheric oxygen. For thermal oxygen degradation, polyester-based polyurethane elastomers (PUEs) are more stable than polyether-based polyurethane elastomers (PUEs) due to that the cohesive energy of the ester group is greater
