analog paper burst Mullen tester

Determination of bursting strength of 70 KPa-- 1400 KPa single layer or multi-layer sheet of paper. Not apply to the determination of composite materials (such as corrugated cardboard sheet or liner)

Principle:

The sample is placed on the elastic rubber membrane, tightly grip the surrounding, sample and membrane freely together with the protrusion, when the hydraulic fluid is pumped at a steady rate, until the sample is broken when the membrane protrusion, the applied the maximum pressure is bursting value of the sample.

Technical parameters:

1. Measuring range: 0 ~ 1000kpa

2. Upper plate inner dia.: 30.5 ± 0.05 mm

3. Under plate inner dia: 33.1 ± 0.05 mm

4. Compression speed: 95 ± mL / min

5. Membrane Thickness: 0.8 to 0.9 mm

6. Upper /under plate concentricity: no more than 0.25 mm
