Shore Hardness - Introduction to Shore Hardness

For products with high elasticity or soft texture, testers can directly use a Shore A hardness tester for testing, such as stationery bottles, TPU TPR plastic film bags, and other products. For products with little elasticity or hardness, a Shore D hardness tester can be used for testing, such as PC, ABS, PP, and other products. If the degree is Shore Axx, it indicates relatively low hardness, while if it is Shore Dxx, it indicates relatively high hardness.

Addendum:

Shaw Brothers' units are not diverse enough:

The unit expression of type A is: HA

The expression of D-type unit is: HD
