Aluminium Phosphide
Formulations based on aluminium phosphide (AlP) are the mostly used products for the control of pests in storages, as well for rodents and other outdoor vertebrates. Aluminium phosphide is created by the fusion of aluminium und red or yellow phosphorus. In contact with ambient air and humidity the very efficient phosphine gas is developed and released.
Pellets
Pellets contain of 56-57% aluminium phosphide as active substance and 43-44% inert components, mainly ammonium carbamate amongst others, that facilitate controlled outgassing of phosphine.
One pellet has a weight of 0.6 g and releases 0.2 g phosphine gas.
Round Tablets
Round Tablets contain of 56-57% aluminium phosphide as active substance and 43-44% inert components, mainly ammonium carbamate amongst others, that facilitate controlled outgassing of phosphine.
One round tablet has a weight of 3 g and releases 1 g phosphine gas.
Bags
Bag products contain of 57% aluminium phosphide as the active substance and inert components that facilitate controlled outgassing of phosphine. This formulation does not contain ammonium carbamate.
The formulation has been integrated in a special bag material (Tyvek) characterized by high levels of strength and elasticity. The Tyvek bag is only permeable to water vapour and phosphine and is practically impermeable to water in the liquid state.
One bag weighs 34 g and releases 11.3 g phosphine gas (see packaging for further information).
