This aluminum phosphite composite uses 460–490°C and 550–580°C decomposition peaks for staged ignition and secondary-combustion protection.
Dual-peak aluminum phosphite decomposition supports earlier and sustained flame protection.
Mixtures of aluminum phosphite with sparingly soluble salts enhance polymer flame retardancy through template-free synthesis.
Hydrolyzing P4O6 with a homogeneous Brønsted acid catalyst at controlled pH levels to produce concentrated phosphorous acid.
Thermally stable pyrophosphonic acid salts provide effective flame retardation in polymer compositions without impacting physical properties.
