Polymethylene polyphenyl polyisocyanate

Dangerous Goods

CAS number:9016-87-9    molecular formula:[-C6H3(NCO)CH2-]n

overview

compound introduction

产品介绍: PMDI是单体(2-环)与聚合(3- 环或更高)二苯基甲烷二异氰酸酯的棕色混合物,在室温下为液 体。较高的PMDI粘度表明其成分中单体物含量较低,多环芳烃 物含量较高,即随着PMDI粘度增加,异氰酸酯的官能度越强。 Product Describtion: A solvent-free product based on 4,4'-diphenylmethane diisocyanate (MDI) containing oligomers of high functionality and isomers.
