Taking into account the circular economy guidelines and results of life cycle analyses of various materials, it was proposed to use a blackcurrant pomace filler in the production process of viscoelastic polyurethane (PUR) foams intended for application as mattresses, pillows, or elements for orthopedics. Open-cell viscoelastic PUR foams containing 10-60 per hundred polyols (php) blackcurrant pomace were prepared. It was found that after introducing the filler to the PUR foam formulation, the speed of the first stage of the foaming process significantly decreases, the maximum temperature achieved during the synthesis drops (by 30 °C for the foam containing 40 php of filler compared to unfilled foam), and the maximum pressure achieved during the synthesis of foam containing 20 php is reduced by approximately 57% compared to the foam without filler. The growth time of the foams increases with increasing the amount of introduced filler; for the foam containing 60 php, the time is extended even by about 24%. The effect of the filler on the physical, morphological, mechanical, and functional performances of PUR foam composites has been analyzed. The use of 60 php as the filler reduced the hardness of the foams by approximately 30% and increased their comfort factor from 3 to 5.
考虑到循环经济准则以及各种材料的生命周期分析结果，有人提议在用于制造床垫、枕头或骨科用品的粘弹性聚氨酯（PUR）泡沫生产过程中使用黑加仑果渣填料。制备了含有10 - 60每百多元醇（php）黑加仑果渣的开孔粘弹性PUR泡沫。结果发现，在将填料引入PUR泡沫配方后，发泡过程第一阶段的速度显著降低，合成过程中达到的最高温度下降（与未填充泡沫相比，含40 php填料的泡沫下降30°C），含20 php填料的泡沫合成过程中达到的最大压力与未填充泡沫相比降低了约57%。泡沫的生长时间随着引入填料量的增加而增加；对于含60 php填料的泡沫，时间甚至延长了约24%。分析了填料对PUR泡沫复合材料的物理、形态、机械和功能性能的影响。使用60 php作为填料使泡沫硬度降低了约30%，并使其舒适系数从3提高到5。
