METHOD FOR PRODUCING FOAM PADS FROM AT LEAST TWO FOAMS, ESPECIALLY POLYURETHANE FOAMS, DIFFERENT ELASTICITY OR. HARD EDUCATIONAL, FLOWABLE, ACCORDINGLY DIFFERENT REACTION MIXTURES

摘要

In order to make foam upholstery having zones of different elasticity or hardness with less expenditure on the mould and at the same time improved reproducibility and resistance to unusual loads, the reaction mixtures are introduced into the mould cavity, only once they have reached a creamy, already viscous state.
