| 摘要 |
Halogen-containing polymers, e.g. PVC, exhibit reduced inflammability and reduced fume density when they contain a hydroxylic magnesium aluminosilicate as a flameproofing additive. A secondary flameproofing additive, e.g. CuO, Cu2O or CuSO4, may be present, and may be deposited on the aluminosilicate. |
