Advancements in Foam Porosity Measurement

Image
The first version of IDM Instruments’ Foam Porosity Tester F0016 was designed and released in the 1980s, in accordance with global industry standards, and was used to determine the ease with which air passed through a cellular structure, namely foam, by comparing the relationship between pressure and flow when subjected to different foam samples. It used vacuum chambers with manometers and was controllable via a manual dial to fine tune flow. This version was purely analogue and required fine use of the dial and flow tubes to be able to give accurate test results. Due to the purely analog design, it was difficult to achieve accurate yet repeatable test results. After more design and upgrades, the second version Foam Porosity Tester F0023 was released in late 2001. Once again improving the accuracy of foam porosity testing. This model boasted variable flow ranges, allowing for more ranges of conditions of testing foam porosities. A huge feature of this model was...

MINIFLEX CLD Why measure foam hardness?   All foamers measure the density of their product. Not all foamers, however, measure foam hardness. Foam hardness has a major influence on the comfort factor of the furniture, bedding or automotive product in which it is used. Variation in hardness is one of the most common complaints from customers. Trying to judge the hardness of a foam sample by hand-feel is almost impossible. Every person will have a different opinion. To ensure consistent Quality Control of foam production, it is necessary to have an industry recognised foam hardness test procedure that will give an accurate, recordable value. The foam industry measures foam hardness by various different tests. These can be grouped as either ILD (Indentation Load Deflection) or CLD (Compression Load Deflection) type tests. The test procedure first measures the thickness of the foam sample (pre-load). It is then compressed 3 times to 30% of its origin...
