본 기술은 (a) 가요성 포움 영역 및 (b) 비-포움 영역을 포함하는 일체화 물품에 관한 것이다. 가요성 포움 영역 및 비-포움 영역은 각각 폴리우레탄 조성물로 제조된다. 일부 구체예에서, 가요성 포움 영역은 중창이고, 비-포움 영역은 바깥창이다. 가요성 포움 영역은 가요성 폴리우레탄 사출 성형된 포움으로부터 제조된다. 비-포움 영역은, 압출되거나 열성형될 수 있는 비-발포된 폴리우레탄으로부터 제조된다. 본 발명은 일체화 물품뿐만 아니라 이를 제조하고 사용하는 방법에 관한 것이다. This technology relates to an integrated article that includes (a) a flexible foam region and (b) a non-foam region. The flexible foam region and the non-foam region are each made of a polyurethane composition. In some embodiments, the flexible foam region is a midsole, and wherein the non-foam region is an outsole. The flexible foam region is made from a flexible polyurethane injection molded foam. The non-foam region is made from a non-foamed polyurethane, which may be extruded or thermoformed. The invention relates to this integrated article, as well as the methods of making and using the same.
