Explanation

The ratio, in kN/m, of the maximum tensile force of a right angle vulcanized rubber specimen at a constant temperature (usually 23 ° C) and a constant speed of stretching [(500 ± 50) mm/min] until fracture to the thickness at the right angle of the specimen belongs to the initial type tear test. Generally speaking, tear strength decreases with the increase of test temperature. The tensile speed also has a certain influence on the tear strength of rubber. With the increase of tensile speed, the tear strength decreases. Tearing property is an important physical property of rubber products. Tearing damage of rubber products during use is one of the common damage phenomena of rubber products. Therefore, the tear strength test of rubber is an important physical property test.
