FKM rubber sheets are high-performance sealing materials based on fluororubber,and their outstanding properties make them widely used in many industrial fields.The hardness of fluororubber sheets is usually expressed by Shore hardness,generally ranging from 70 to 80 Shore A.This hardness range ensures the best performance of fluororubber sheets in various applications.
The hardness of fluororubber sheets has a significant impact on their physical properties.Higher hardness means better wear resistance and load-bearing capacity,which is particularly crucial for applications requiring high durability and reliability.For instance,in industries such as aerospace and petrochemicals,equipment often operates under extreme temperatures and pressures.Using fluororubber sheets with moderate hardness can effectively prevent seal failure due to wear or deformation.
The heat resistance of fluororubber sheets is also closely related to their hardness.Experimental data shows that after special heat treatment,the hardness change rate of fluororubber sheets does not exceed 5%even after temperature cycling tests from-40°C to 250°C.This indicates that fluororubber sheets can maintain stable performance in long-term high-temperature environments and are less likely to experience hardness changes,thus ensuring reliable sealing effects under various harsh conditions.

Hardness testing is one of the important steps to ensure the quality of fluororubber sheets.By using professional hardness testing instruments to test the hardness of fluororubber sheets,their load-bearing capacity and wear resistance can be accurately evaluated.Such strict testing procedures not only guarantee product quality but also help manufacturers provide customized solutions based on different customer needs.
In addition to hardness,other physical parameters of fluororubber sheets are also worth noting.For example,the specific gravity of fluororubber sheets is approximately 2.0,the tensile strength is 7 MPa,and the elongation is around 350%.These parameters collectively determine the mechanical properties of fluororubber sheets,enabling them to perform well in practical applications.Good tensile strength and ductility allow fluororubber sheets to maintain their shape and function when subjected to external tensile forces,and they are less likely to break or deform.
FKM rubber sheets are widely used in various demanding industries,including aerospace,mechanical manufacturing,and petrochemicals.In these fields,fluororubber sheets not only need to have high-temperature resistance,oil resistance,acid and alkali resistance,and ozone resistance,but also excellent flame retardancy.They can operate stably within a temperature range of-20°C to+230°C and are suitable for air,oil-based media,and 30%concentration of acid and alkali environments.Therefore,choosing the appropriate hardness is crucial for ensuring the success of fluororubber sheets in specific applications.
