Толуолдиизоцианат (ТДИ)

ТДИ представляет собой бесцветную или бледно-желтую жидкость с температурой плавления около 22 °C и характерным едким запахом. Из-за температуры плавления близкой к комнатной, ТДИ часто застывает в бочках при транспортировке, поэтому их нужно выдерживать на складе при повышенной температуре для возможности дальнейшего использования.
