Silicone Surfactant
|
L-3100 and L-3200 are two new silicones developed
specifically for TDI HR molded |
Systems in which the right combination of shear stability,
cell structure and foam openness is difficult to achieve.
Silicone L-3100 is designed to provide open foam with
good bulk stability, whereas silicone L-3200 provides
good cell structure and shear stability.
By blending silicones L-3100 and L-3200, OSi Specialties
can customer-design a silicone to precisely meet a broad
range of customer needs for the right balance of cell-opening,
bulk stability and shear stability.
L-3150 is one such blend. Other combinations yield blends
that will show properties that tend to be closer to those
of the major component.
