LESSON 27: HOW TO MEASURE TDI INDEX IN YOUR FORMULATION FOR FOAMING PROCESS.

In this presentation, you will notice that especially in Nigeria when foam is hard it become a quality foam therefore , the mentality is been built in people mind and some foamers are trying to increase the TDI index beyond certain range to harden the foam. checking this index to ensure that is far lesser than the one measure using the formula seen. This is the European standard that will use ensure the safety of the factory. TDI should be well manage in term of control and restriction. In Nigeria, NAFDAC is doing well in monitoring the industrial consumption and the personnel. The Global safety exposure limits per 8hours is 0.005ppm. The stoichiometric balance for TDI in foaming process is 100 , below the 100 is rich with polyol with less crosslinking as well as slow curing process and above 100 is rich with TDI and has effective crosslinking. watch the video presentation.
