HomeTechnology Characteristics of Hose Elastomers

Typical prosperity of hose elastomers

Common characteristics of hose elastomers are shown below. Their characteristics will change when the compound changes to meet specified applications. When you select suction hose or other flexible rubber hoses, consult with this table and then you will be a little clear about the material of the hose.

The table below lists the common elastomers properties including flame resistance, oil resistance, ozone & weather resistance and performances of standing with extreme temperatures. Each material has its unique performance and none is excellent from A to Z. Depending on specific application, correct combination should be made to satisfy the application.
