TPU Characteristic
Hardness is an indicator of a material's ability to resist deformation, nicks, and scratches.
Hardness of TPU is usually measured by Shore A and Shore D durometer.
Shore A is used for softer TPU and Shore D is used for harder TPU.
Hardness is mainly determined by the content of hard segment in TPU structure.
The higher the content of hard segment, the higher the hardness of TPU will be.
