Usage

General Description

(Bibenzyl-4,4'-diyl)diisocyanate is a chemical compound that is primarily used as a building block in the synthesis of polyurethane polymers. It consists of two isocyanate functional groups attached to a bibenzyl backbone, and its structure allows it to react with polyols to form polyurethane materials with varying properties such as flexibility, durability, and chemical resistance. However, (Bibenzyl-4,4'-diyl)diisocyanate is known to be a potent respiratory sensitizer and can cause allergic reactions in people who are exposed to it, therefore it must be handled with appropriate safety precautions. Its versatility and linkage to the production of polyurethanes makes it an important chemical in the manufacturing industry.
