- Component Al-1 (125 g) was weighed in a 500 mL paper cup together with components Bl-1, B2-1 and C-1 and premixed with a high-speed stirrer for 10 seconds. This was followed by the addition of the component Bl -2 and a mixing of 10 seconds at the same stirring speed. Finally, component D-1 was added to this mixture, mixed for 7 seconds, and the mixture was transferred to a prepared 20 cm x 20 cm x 15 cm paper box.
- the height of the flexible polyurethane foam blocks was about 14-15 cm.
- the finished flexible polyurethane foam was stored in the paper box for about 20-24 hours before this Test was sawn into test specimens.
- the compression hardness and the bulk density of the flexible polyurethane foams was determined in accordance with DIN EN ISO 3386-1-98.
