Project Description

Rubber Tensile Testing Machine

Rubber Tensile Strength Testing Equipment Manufacturer

Rubber Tensile Testing Machine is the most popular testing machine intended to measure the tensile strength of rubber or elastomer and conduct compression, bending, shear, tear, peel, and other tests by means of various jigs.

The tensile strength of rubber or elastomer refers to the maximum uniform plasticity stress produced by the material and the ultimate ability of the material to resist tensile damage.

Tensile performance is one of the important indexes of rubber materials. The service life of the rubber is related to its tensile strength. When inspecting the quality of the finished product, designing the rubber formula, arranging the production process, and determining the rubber aging and liquid resistance properties, the tensile property usually has to be tested for identification. Therefore, the tensile property is one of the essential and routine testing items for rubber. The load per unit thickness when the sample is torn is the tearing strength.

Test Standards

ISO 37, DIN 53504, ASTM D412, ASTM D624, ASTM D638, JIS K6301, ISO 34-1 ISO34-2, etc.

Test Principle

A sample is positioned between two clamps, one is a moving gripper, and the other is a stationary gripper. Under the movement of the moving clamp, the specimen mounted on the both clamps is pulled up or compressed under a certain force. Through the force value sensor and the built-in displacement sensor of the machine, the force value change and the displacement change during the test are collected in real time by the data acquisition system. The test results can be automatically calculated by the system and presented via a monitor, and the test results are editable and can be stored by users.
