Diizocyaniany

Diizocyjaniany is the Polish term for diisocyanates. Diisocyanates are organic compounds containing two isocyanate functional groups (-N=C=O). These chemicals are highly reactive and are primarily used in the production of polyurethanes. Polyurethanes are a versatile class of polymers found in a wide range of products including foams, coatings, adhesives, elastomers, and fibers.

The most common diisocyanates are toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI). TDI is typically used in the production of flexible polyurethane foams, often found in furniture and bedding. MDI is used for both rigid and flexible foams, as well as in applications like insulation and automotive parts. Other diisocyanates include hexamethylene diisocyanate (HDI), used in coatings and elastomers, and isophorone diisocyanate (IPDI), known for its good weathering resistance.

Due to their reactivity, diisocyanates can pose health risks. Exposure can occur through inhalation of vapors or dust, or through skin contact. Respiratory sensitization is a significant concern, leading to asthma-like symptoms. Skin irritation and sensitization can also occur. Therefore, strict safety precautions, including proper ventilation and personal protective equipment, are essential when handling these chemicals. Regulatory bodies often set exposure limits to protect workers and the public.
