The tensile strength and tear strength of silicone rubber are two different concepts.
They are related but different. Let's take a look at them together:
1. The overview of the two is different:
a). Overview of tensile strength: It is the critical value of the transition of silicone rubber from uniform plastic deformation to local concentrated plastic deformation, and it is also the maximum load-bearing capacity of silicone rubber under static tensile conditions.
b). Overview of tear strength: It is a term defined in a test method (Elmendorf method) for determining the tear resistance of films or sheets.
2. The properties of the two are different:
a). The nature of tensile strength: the resistance of the material to the maximum uniform plastic deformation.
b). The nature of tear strength: the force required to tear a thin specimen.
3. The units of the two are different:
a). The unit of tensile strength: the unit is MPa.
b). The unit of tear strength: the unit is N.
