Foam Tear Resistance Test Machines

1 . Usage:

Foam Tear Resistance Test Machine is used to test the tensile strength , tearing force , peeling and adhesive force- the physical property of strength resistance .

2 . Theory :

Foam Tear Resistance Test Machine adopts the electronic tensile meter , use the motor to make displacement of the fixture .

Place the fixture with sample between the upper and lower fixture , use a given speed to pull the upper fixture upward , and the upper load cell with sensor the tensile strength , and convert the strength into voltage sign and output to the display screen . And the strength value will be displayed automatically .
