TDI Flexible Slabstock Low Emission Additives

Handmix rate of rise comparison tests were performed using the same equipment and process as described for TDI and MDI hand mix foam. The formulations used are listed in Table 1.42 and the rate of rise data reported in Table 1.43. Dabco BLV with Dabco T-9 was used as the industry standard catalyst control for the water blown flexible slabstock foam formulations. The silicone surfactant used in the reported flexible slabstock formulations was DC5160. All water blown formulations were made at densities of 23 kg/m.  

Formulations from Table 1.42 were used in rate of rise catalyst comparisons and the results are summarised in Table 1.43. The data suggests there is no significant change in reactivity when comparing the control formulation (XXXV) to the experimental 

Dabco NE600 in combination with Dabco NE500 or Dabco NE600 as a sole amine catalyst used with increased levels of T-9 provides for equal or improved performance compared to Dabco BLV in all water-blown flexible slabstock foam. In all cases, these catalyst combinations can completely replace Dabco BLV and eliminate amine emissions from the flexible slabstock foam.
