What is the typical Shore hardness of fluororubber

The Shore hardness of fluororubber is generally between 65 and 90 Shore A, while the hardness of raw rubber itself is between 68 and 75 Shore A

How to measure the hardness of fluororubber

Make fluorine rubber into products (or vulcanize with basic formula) and test the Shore A hardness of rubber according to the standard

Hardness of fluorine rubber sealing ring: between 50 and 90 degrees (Shore A)

Shore hardness refers to the reading of the value measured by a Shore hardness tester, which is measured in degrees. The description method is divided into two types: A and D, representing different hardness ranges. Those below 90 degrees are tested with a Shore A hardness tester and the data is obtained. Those above 90 degrees are tested with a Shore D hardness tester and the data is obtained. Therefore, generally speaking, for a rubber or plastic A D
