A-33 imparts a high level of activity and good
physical properties to flexible foam systems. |
Optimum performance of this catalyst can be achieved when
it is used in conjunction with A-1 or A-10 in flexible
foam formulations.

| ¢ºPerformance Evaluation |
| |
A-33 was evaluated using bench foam
techniques. The effects of varying tin
at constant |
|
| amine and varying amine at constant tin
were both evaluated. The ranges of tin and
amine concentrations were well within the
"operating range" of each. The dependent
variables measured were: reactivity, top collapse,
height of rise, breathability, density, cell
count, and foam hardness(IFDs). Top and bottom
gradients for breathability and density were
defined. |
