摘要： Molded, soft composite articles such as seat cushions are made by (a) applying a composition which forms a soft elastomer to all interior walls of an open mold, (b) introducing a composition which will react to form a low density, high resiliency, flexible foam under molding conditions into the mold in a manner such that the foam-forming composition will be substantially completely within the elastomer-forming composition; (c) closing the mold (i) prior to introduction of the foam-forming composition or (ii) at some point during or subsequent to introduction of the foam-forming mixture but before foam formation is completed and (d) allowing the foam-forming mixture to form a foam. The composite articles produced by this simple one-step process are characterized by good cushioning characteristics, good abrasion resistance and good mold reproducibility. This molding process generates less waste and requires less labor and equipment than current commercial processes.
摘要翻译：通过（a）将形成软质弹性体的组合物施加到开放模具的所有内壁上，（b）引入将反应以形成低密度，高回弹性的组合物，在模塑条件下将柔性泡沫以使得泡沫形成组合物基本上完全在弹性体形成组合物内的方式加入到模具中; （c）在引入泡沫形成组合物之前关闭模具（i），或（ii）在引入泡沫形成混合物期间或之后的某个时间点，但在泡沫形成完成之前，以及（d）形成混合物以形成泡沫。通过这种简单的一步法生产的复合制品的特征在于具有良好的缓冲特性，良好的耐磨性和良好的模具再现性。与目前的商业流程相比，这种成型过程产生的废物少，劳动力和设备要少。
