这是一种具有高可塑性的聚氨酯多孔泡沫。
它在结构上分为高密度表层和低密度芯部，在一次操作中同时成型。
聚氨酯自结皮产品广泛应用于体操器械的运动器械座垫、靠背、跪垫、把手、脚踏板、自行车鞍座、运动护圈等；也广泛应用于医疗器械，如一体成型座椅、手术台封边、物品挂架、轮椅手柄等。
自皮产品采用反应注射成型（RIM）一次成型，因此具有坚韧致密的外皮和橘皮组织核心。形成的表皮厚度从零点几毫米到5毫米不等，表皮密度从600到1200公斤/立方米不等，而内核的密度为每立方米数百公斤。
皮层和芯层是一个整体。连续、光滑、柔软的表层可以保护泡沫芯材免受机械损伤。整体PU半硬质泡沫系列根据配方不同，密度和硬度也不同。
聚氨酯的特点是在成型过程中可以与填充材料烧结为一体。这种泡沫的基本特点是：极高的抗冲击性、重量轻、生产率高、硬度和耐磨性可变、弹性持久、表面易着色、全身易着色、可插入增强。
