Weband MDI, TDI and HDI account for more than 95% of this total volume. Since there are no suitable alternatives for the majority of the uses, the use is not expected to decline in near future. Also consumers may be exposed to diisocyanates from products containing diisocyanates, particularly glues. WebISO-CHEK® is the only filter-based sampling system that simultaneously traps and separates both monomers and oligomers at the point of collection for highly sensitive physical and chemical characterizations of diisocyanates including HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI.
