多亚甲基多异氰酸酯 (CAS No.9016-87-9)
- 物化性质
- 浅黄色至褐色粘稠液体,有刺激性气味。相对密度(20℃/20℃)1.2,燃点218℃,凝固点<10℃,黏度(25℃)200~1000mPa·s。升温时能发生自聚作用。溶于氯苯、邻二氯苯、甲苯等。蒸气压低,仅为TDI的百分之一,故毒性很低,空气中容许浓度0.2mg/m3。PAPI实际上是由50%MDI与50%官能度大于2以上的多异氰酸酯组成的混合物。存储需远离火源,保持容器密封。

English description(英文原文,共 1098 字符)
Product Name:Polymethylene polyphenyl polyisocyanate
English Name:Polymethylene polyphenyl polyisocyanate
CAS No.:9016-87-9
Aliases:PAPI, Polymeric MDI, PMDI
Molecular Formula:C8H7NO2
Physical Properties:Light yellow to brown viscous liquid with a pungent odor. Relative density (20°C/20°C): 1.2. Fire point: 218°C. Freezing point: <10°C. Viscosity (25°C): 200–1000 mPa·s. It can undergo self-polymerization upon heating. Soluble in chlorobenzene, o-dichlorobenzene, toluene, etc. Low vapor pressure, only 1% of TDI, hence low toxicity. Permissible concentration in air: 0.2 mg/m³. PAPI is actually a mixture of 50% MDI and 50% polyisocyanates with functionality greater than 2. Store away from fire sources and keep container sealed.
Uses:Used for manufacturing polyurethane materials, foams, and adhesives. The products are widely applied in construction, automotive, and electrical industries as thermal insulation materials or cushions.
