- polymethacrylimide foams represent sensitive systems and are difficult to optimize in terms of the foaming behavior.
- flame retardant stabilizers in such foam formulations reduce or prevent the foamability.
- Flame retardants some of which contain antimony oxides, can also be used phosphorus-containing compounds. Phosphorus compounds are preferred because of lower smoke toxicity in case of fire.
- Phosphorus compounds include phosphines
- Phosphine oxides Phosphine oxides, phosphonium compounds, phosphonates,
- Phosphites and / or phosphates may be organic and / or inorganic in nature. To date, however, no flame retardant is described in the prior art, with respect to comparable
- methacrylic acrylonitrile foams can be stabilized according to CN 101 544 720 with chlorinated flame retardants.
- chlorinated systems are not preferred for various reasons, especially in connection with flame retardancy or for reasons of health protection.
