甲苯二异氰酸酯(TDI)90％以上的世界消费量用于家具、建筑物和运输等的柔软聚氨酯泡沫生产中。较小的应用是硬泡沫材料、粘合剂、油漆、混凝土密封剂尼龙6的交联剂以及作为制取聚氨酯涂料与聚氨酯弹性体的中间体等。全球80％的二苯甲烷二异氰酸酯(MDI)用于生产聚氨酯泡沫,聚氨酯泡沫多数用于建筑,也用于冷冻、包装和保温。硬泡沫用于隔热,软泡沫用作家具、床垫和
Toluene diisocyanate (TDI) World consumption of more than 90% Used in the production of flexible polyurethane foams for furniture, buildings and transport. Smaller applications are rigid foams, adhesives, paints, concrete sealants and crosslinking agents for nylon 6 as well as intermediates for the preparation of polyurethane coatings and polyurethane elastomers. 80% of the world’s diphenylmethane diisocyanate (MDI) is used in the production of polyurethane foams, most of which are used in construction as well as in freezing, packaging and insulation. Hard foam is used for thermal insulation, soft foam is used for furniture, mattresses and
