Uses |
It mainly used for the raw materials of TDI and polyether initiator. TDA as a polyether initiator made the polyether, The foam being made of this polyether have uniformity and meticulous properties, and can improve the foam’s performance of heat insulation and it’s the measurement of low-temperature performance.
It is used as chemical intermediate in order to epoxy resin curing agent, dye intermediates.
