HT-9756 Computer Servo Control Hardness Tester For Compounded Foam
Computer Servo Control Hardness Tester For Compounded Foam
Among the seats for motorcycle or automobile, the quality of the compounded foam inside matters so much if the passenger is comfortable sitting on it.
This is to press first 75 % of the sample thickness, release and then press 25% still for 20 seconds and then record its force. That would be the hardness of the compounded foam.
