HARTDUR 115 (NDI)

Common Name: NDI
Similar Name: 1,5-Naphthalene diisocyanate
Molecular Formula:C12H6N2O2
CASNumber:3173-72-6
 

HARTDUR 115 (NDI), formally known as 1,5-naphthalene diisocyanate, represents a distinctive class of aromatic isocyanates, setting itself apart from conventional varieties such as methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI) through its enhanced structural rigidity and elevated melting point. When integrated into polyurethane (PU) formulations, HARTDUR 115 significantly augments the structural integrity and longevity of the end products, offering superior resistance to wear and high temperatures. This attribute renders it particularly suitable for the fabrication of high-quality, durable mechanical components. Furthermore, HARTDUR 115 is utilized as a versatile chemical intermediate in the synthesis of advanced agricultural chemicals and pharmaceutical compounds.

HARTDUR 115 (NDI) is pure naphthylene -1,5- diisocyanate (NDI) and is supplied in the form of fine white crystalline flakes. Its vapor pressure at room temperature is below 10-4mbar. Permissible in the air at working places according to the Federal Republic of Germany is 0.02 ppm = 0.18 mg/m3. This value is not allowed to exceed even for short periods. Being exceptionally reactive, NDI must be treated as a dangerous material and it must be handled with care. The potential risks of HARTDUR 115 (NDI) depend mainly on the extent to which isocyanate dust, vapors, or aerosols are formed during the processing of this product. The circumstances and operations in which workers may be exposed to HARTDUR 115 (NDI) in any of these forms are as follows: dust may rise from the solid material while it is being weighed or batch feeding into reaction vessels; vapors and aerosols are formed in the cross linking of hot prepolymer batches containing an excess of NDI and in the production of castings (the aerosols owe their formation to the cooling and condensation of hot isocyanate vapors).

Storage  Caution:

HARTDUR 115(NDI) is sensitive to moisture. Water reacts with all diisocyanates to form insoluble urea derivatives. HARTDUR 115(NDI) should be stored in tightly sealed containers in cool and dry conditions. After using, the lid must be sealed immediately in case of dysfunction.
