As an elastomer, TPU is a material between rubber and plastic. This can be seen from its rigidity. The rigidity of TPU can be measured by its elastic modulus.

The elastic modulus of rubber is usually 1-10MPa, TPU is 10-1000MPa, and plastic (nylon, ABS, polycarbonate, polyoxymethylene) is 1000-10000MPa.

The hardness range of TPU is quite wide, from Shore A60 to Shore D80, and it has high elasticity in the entire hardness range; TPU is flexible in a wide temperature range (-40～120℃) without plasticizer; TPU has good resistance to oils (mineral oil, animal and vegetable fats and lubricants) and many solvents; TPU also has good weather resistance and excellent resistance to high-energy rays. The well-known wear resistance, tear resistance, and flexural strength are all excellent; high tensile strength, high elongation at break, long-term compression and low permanent change rate are all the significant advantages of TPU.
