Aromatic Isocyanates (TDI & MDI) Information
What are Aromatic Isocyanates:
Aromatic Isocyanates are isocyanates where the NCO group is directly attached to an aromatic ring. Aromatic Isocyanates like TDI (toluenediisocyanate) and MDI (methylenediphenyl diisocyanate) represent the largest market for diisocyanate monomers. They are used in applications where color stability and UV resistance are not necessary. These isocyanates are used in polyurethane and polyurea foams, elastomers, adhesives, and coatings. Under catalyzed conditions, aromatic isocyanates are extremely fast in reacting with polyols.
Exposure to chemicals with low vapor pressures, like aromatic isocyanates, can occur though skin contact with contaminated solvents or surfaces. Aromatic isocyanates also present a respiratory sensitization hazard.
Measuring Aromatic Isocyanates: What type of Aromatic Isocyanate component are you looking for?
All sensors require a yearly calibration to ensure your gas measurements are accurate and performing within manufacturer standards. This page is desiccated to the individual manufacturers we represent and their specific calibration procedures.
Calibration costs do vary, see below to get an estimate:
Calibration Fee: $150
Analyzer Calibration Fee: $300
PM Calibration Sensor Fee: $330
Genie Calibration Fee: $265
ATI Calibration Fee: $205
