应用二氯甲烷生产软质聚氨酯泡沫塑料

Application of Methylene Chloride to Producing Flexible Polyurethane Foam

讨论了用二氯甲烷替代一氟三氯甲烷进行软质聚氨酯泡沫塑料的生产。小试结果表明，用二氯甲烷生产各种密度的软质聚氨酯泡沫塑料，确实是较全面的一氟三氯甲烷的代用品。

This article is a study of methylene chloride as a substitute for trichloro-fluoromethane in producing flexible polyurethane foam. The experimental results suggest that methylene chloride ist a good substitute which can instead of trichloro-fluoromethane in the production of different kind of density flexible polyurethane foam.
