Ammonium polyphosphate, e bitsoangAPP, ke phosphate e nang le naetrojene e nang le ponahalo ya phofo e tshweu. Ho ya ka tekanyo ya yona ya polymerization, e ka arolwa ka mefuta e meraro: polymerization e tlase, polymerization e mahareng le polymerization e phahameng. Ha tekanyo ya polymerization e le kgolo, ho qhibiliha ha metsi ho ba nyane. Crystalline ammonium polyphosphate ke polyphosphate e sa qhibiliheng metsing le e nang le ketane e telele. Ho na le mefuta e mehlano ho tloha ho I ho isa ho V.

Boemo bo phahameng ba polymerization kristale ea mofuta oa II ammonium polyphosphate e na le melemo e meholo lefapheng la thepa ea polymer ka lebaka la ho se qhibilihe ha metsi hantle, mocheso o phahameng oa ho bola, le ho lumellana hantle le thepa ea polymer. Ha e bapisoa le li-retant tsa malakabe tse nang le halogen, ammonium polyphosphate ea mofuta oa II ea kristale e na le litšobotsi tsa chefo e tlase, mosi o tlase, le inorganic. Ke mofuta o mocha oa retant ea malakabe e sa tloaelehang e sebetsang hantle haholo.

Nalane ea nts'etsopele ea ts'ebeliso
Ka 1857, ammonium polyphosphate e ile ea ithutoa ka lekhetlo la pele.
Ka 1961, e ile ea sebelisoa e le manyolo a nang le mahloriso a mangata.
Ka 1969, ts'ebeliso ea mahlale a macha e ile ea atolosa ts'ebeliso ea eona ho li-retantants tsa malakabe.
Ka 1970, United States e ile ea qala ho hlahisa ammonium polyphosphate e thibelang malakabe.
Ka 1972, Japane e ile ea qala ho hlahisa ammonium polyphosphate e thibelang malakabe.
Lilemong tsa bo-1980, Chaena e ile ea ithuta ammonium polyphosphate e thibelang malakabe.

Likopo tse kentsweng
Ammonium polyphosphate e sebelisoa haholo e le sesebelisoa sa kalafo se thibelang malakabe bakeng sa polasetiki, rabara le likhoele;
E ka boela ea sebelisoa ho lokisa lipekere tse thibelang mollo tse kenang ka hare ho seretse bakeng sa kalafo ea tšireletso ea mollo ea likepe, literene, likhoele le mehaho e melelele, hammoho le lehong le pampiri tse thibelang mollo.
E boetse e sebelisetsoa ho hlahisa li-stima-mollo tsa phofo e ommeng bakeng sa ho tima mollo o moholo masimong a mashala, lilibeng tsa oli le merung;
Ho phaella moo, e ka boela ea sebelisoa e le manyolo.

'Maraka oa lefats'e
Ka ntshetsopele ya di-retant tsa malakabe tsa lefatshe ka bophara ka lehlakoreng la di-halogen-free, di-intumescent flame retant tse sebedisang ammonium polyphosphate e le thepa e tala ya mantlha di fetohile sebaka se chesang indastering, haholoholo tlhokeho ya mofuta wa II-ammonium polyphosphate e nang le tekanyo e phahameng ya polymerization.

Mabapi le kabo ea libaka, Amerika Leboea, Europe Bophirima, Japane le sebaka sa Asia-Pacific (ntle le Japane) ke limmaraka tse 'ne tse kholo tsa ammonium polyphosphate. Tlhoko ea ammonium polyphosphate 'marakeng oa Asia-Pacific e holile haholo' me joale e se e le 'maraka o moholo ka ho fetisisa oa bareki lefatšeng oa ammonium polyphosphate, o ikarabellang bakeng sa 55.0% ka 2018.

Mabapi le tlhahiso, bahlahisi ba di-APP ba lefatshe ka bophara ba shebane haholo Amerika Leboya, Yuropa le Chaena. Mefuta e meholo e kenyeletsa Clariant, ICL, Monsanto ho tloha USA (PhoschekP/30), Hoechst ho tloha Jeremane (Exolit263), Montedison ho tloha Italy (SpinflamMF8), Sumitomo le Nissan ho tloha Japane, jj.
