ActivePlastics—Determination of the isomer ratio in toluene diisocyanates for use in the production of polyurethanes
塑料 用于聚氨酯生产的甲苯二异氰酸酯异构比的测定
Application Summary AI generated
This standard specifies a gas chromatography method for determining the ratio of 2,4- and 2,6-toluene diisocyanate (TDI) isomers in raw materials used for polyurethane production. It is applied in quality control laboratories within the chemical and plastics industries to ensure the correct isomer composition of TDI, which directly affects the reactivity and final properties of polyurethane foams, coatings, and elastomers.
