TEGOSTAB® B 89120 is a high molecular weight polysiloxane–polyoxyalkylen block-copolymer that can be used for the preparation of mechanically frothed PU foams. It is free of VOC.
Typical Applications
TEGOSTAB® B 89120 can be used as efficient stabilizing additive in froth processes. TEGOSTAB® B 89120 allows for the preparation of fine and regular PU froth foams, which stand out due to a superior stability during processing. It is also suitable for highly filled formulations often used in froth technology.
Benefits at a glance
- Superior stabilization of mechanically frothed PU foams, especially at low densities (down to 150 g/l – depending on filler concentration)
- Formation of fine and homogeneous cell structure
- Low tendency for pine hole formation at the foam surface and hence, good surface properties of the cured foam
- Low VOC profile
