How much is IDM automatic foam permeability tester

F0031IDM automatic foam permeability tester, used to monitor the air permeability of polyurethane foam materials. The principle of the machine is to test the difficulty of air passing through the honeycomb structure in foam. The final permeability value is an indirect test value to determine the performance of the honeycomb structure in foam.

F0031IDM automatic foam permeability tester，Designed according to current international standards, it is specially used to test polyurethane foam materials. The test port is 50 * 50 * 25mm, and after placing the sample, a vacuum is formed insideRoom, automatically apply continuous air pressure after the experiment begins. Before the experiment begins, users can set the pressure value on the touch screen. After the experiment begins, the breathability tester passes a certain rate toAchieve the set pressure value and automatically complete the test.

Scope of application:

The sponge permeability tester can be used to measure the permeability of viscous foam (memory foam), sponge and other polyurethane materials.

The size or difficulty of airflow when air passes through the honeycomb structure of a material, that is, the breathability of the material, can ultimately be expressed as a specific measurement value, which indicates the breathability of the material.

When testing, place the sample in the sample placement port of the instrument, and set the air pressure value inside the instrument through the touch screen and maintain it constant. The air flow rate passing through at this air pressure value is the permeability of the sample.

Applicable standards:

AS-2282.14; ASTM-D3574-TestG ; ISO-7231 BS-EN-ISO-7231; DIN-EN-ISO-7231; EN-ISO -7231； JIS K6400。

Equipment principle:

Place the cut sample at the sample placement port of the device, adjust the selected air pressure (pressure difference inside and outside the device placement port) through the touch screen, and maintain a constant air pressure during the testing process. The value obtained after the test is the flow rate of air passing through the sample, that is, the air permeability of the sample.

Main components of the equipment:

1. Air flow meter

2. Pressure gauge

3. Vacuum motor

4. Touch screen control system

Sample preparation:

Size: 51.0 ± 0.3mm X 51.0 ± 0.3mm X 25.0 ± 0.5mm

Quantity: Take a total of 3 samples from different positions and directions (front and back) of the test object

Tool: Use sponge cutting band saw

Note: The size of the sample cutting should conform to the size of the "sample placement port" to avoid affecting the test results. Try to avoid damaging the honeycomb structure inside the material during cutting.

Note: Due to technological advancements, information may be changed without prior notice. The actual product in the future shall prevail.
