How is the hardness of Nomex Braided Sleeve measured?

In daily life, how do we know the hardness of Nomex Braided Sleeve, and how to express the hardness of Nomex Braided Sleeve, Xiaobian will answer for you.

The hardness of Nomex Braided Sleeve is expressed by Shore hardness, which refers to the reading of the value measured by Shore hardness meter, and its unit is "degree". Its description method is divided into two types, A and D, which represent different hardness ranges respectively. The hardness below 90 degrees is tested by the Shore A hardness tester, and the data is obtained, and the data is obtained by the Shore D hardness tester for 90 degrees and above, Therefore, generally speaking, for a silicone or plastic product, during the test, the tester can make a prediction before the test based on experience, so as to decide whether to use the Shore A hardness tester or the Shore D hardness tester for testing.
Generally, for products with relatively large elasticity or softness, testers can directly judge them with the Shore A hardness tester, such as: stationery glue bottles, TPU, TPR, plastic film bags and other products. If the hand feels basically inelastic or hard, it can be tested with a Shore D hardness tester, such as PC, ABS, PP and other products. If the degree is Shore Axx, the hardness is relatively low, and if it is Shore Dxx, the hardness is relatively high.
In addition, Shaw's units are not comprehensive enough:
1. The unit expression of type A is: HA
2. The expression of D-type unit is: HD.
