Exolit

Flexible polyester foam (slabstock foams)
Advantages of Exolit:
> No emissions
(e.g. low fogging and VOC-values)
> Solid easily dispersible in polyol
(Exolit AP)
> Usable in conventional production
facilities by adding directly into the
mixing head (Exolit OP)
Products
> Highly effective
> Only slight influence on
mechanical properties
> No contribution to corrosive
gases in the case of fire
> Reduced foam dripping
in the case of fire (Exolit AP)

The addition rate to achieve a specific fire classification depends heavily on the polyol, blowing agent and foam density.
