Isophorone Diisocyanate (IPDI), (CAS # 4098-71-9), also known as 5-Isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane.
HMDI and IPDI are intermediate materials used in the production of Polyurethane (PU), a versatile material having the advantages of both rubber and plastic. Wanhua Chemical America’s HMDI and IPDI commercial grade products are marketed as specific intermediate materials to the global PU manufacturing sector. HMDI and IPDI are both aliphatic diisocyanate (ADI) which are specialty intermediate chemicals used primarily to make durable coatings, adhesives, sealants, elastomers, and textiles, among other products. They will be imported in similar conditions as separate chemicals, not part of a mixture
