Computerized sponge compression strength testing machine

1. introductions

The microcomputer-controlled sponge pressure testing machine is equipped with a compression platen, which can be used to test the compression properties of thermal insulation sponge, thermal insulation sponge, sound-absorbing sponge, sound insulation sponge, sponge scouring pad, fire-retardant sponge, sofa sponge and other products, such as compressive strength, the compressive stress and compressive elastic modulus at 10% deformation, the tensile properties of the material can also be tested when equip with tensile test fixtures.
