AU (Polyester urethane elastomer)

Grade of TPU. Grades are not interchangeable.

Polyester urethane rubber, ASTM AU. It is stored under the existing TPU family so polyurethane is not opened as a second material. AU does not mean every TPU grade is a polyester urethane elastomer. This entry identifies the family only. It does not state hardness, dimensions, stock, a certificate, or a lead time.
