O le Propylene glycol methyl ether acetate o se ituaiga o solvent fa'aonaponei. O lona molecule e aofia ai le ether bond ma le carbonyl group, ma o le carbonyl group e fausia ai le fausaga o le ester ma e aofia ai le alkyl group. I le molecule lava e tasi, e iai vaega e le o ni polar ma vaega polar, ma o vaega fa'atino o nei vaega e lua e le gata ina fa'atapula'aina ma tete'e le tasi i le isi, ae fa'atino fo'i a latou matafaioi totino. O le mea lea, e iai sona solubility fa'apitoa mo mea e le o ni polar ma mea polar. O le Propylene glycol methyl ether acetate na fa'aputuina e ala i le esterification o le propylene glycol methyl ether ma le glacial acetic acid e fa'aaoga ai le concentrated sulfuric acid o se catalyst. O se solvent fa'apisinisi fa'aonaponei e sili ona lelei ma maualalo le oona, e malosi lona gafatia e fa'ata'ape'ape ai mea polar ma mea e le o ni polar, e talafeagai mo ufiufi maualuga, solvents vaitusi o polymers eseese, e aofia ai le aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin ma nitrocelluloses. O nisi o ia mea. O le propylene glycol methyl ether propionate o le vailaʻau sili lea ona lelei mo vali ma vaitusi, e talafeagai mo le unsaturated polyester, polyurethane resin, acrylic resin, epoxy resin ma isi mea faapena.

E tusa ai ma le "2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report" na tuʻuina mai e le Xinsijie Industry Research Center, i le taimi nei, ua faasolosolo malie ona faʻaleleia le tekinolosi gaosiga o le propanediol methyl ether acetate a Saina, ua faasolosolo malie ona faʻaleleia lona faʻatinoga atoatoa, ua faasolosolo malie ona faʻalauteleina lona fanua faʻaoga, ma ua faasolosolo malie ona atiaʻe i semiconductor, photoresist substrate, copper clad plate ma isi maketi. O loʻo faʻatupulaʻia malie le manaʻoga o le maketi. I lalo o lenei talaaga, o le tele o maketi o le propylene glycol methyl ether acetate i Saina o loʻo faʻaalia ai se aga faʻateleina i lea tausaga ma lea tausaga. Mai le 2015 i le 2022, o le tele o le maketi o le propylene glycol methyl ether acetate i Saina na faʻateleina mai le 2.261 piliona yuan i le 3.397 piliona yuan, faʻatasi ai ma le fua faʻatatau o le tuputupu aʻe faʻaletausaga o le 5.99%. I totonu oi latou, o le maketi kemikolo a Tianyin na mafua ai le tele o le vaega, e oʻo atu i le 25.7%; sosoo ai ma le Hualun Chemical, e 13.8% o le maketi; O le tulaga tolu o le Jida Chemical, faatasi ai ma le sea maketi e 10.4%. Faatasi ai ma le atinaeina pea o le alamanuia propylene glycol methyl ether acetate a Saina, ua faasolosolo malie ona faaleleia atili le fausaga o le gafatia, ua faasolosolo malie ona aveesea le gafatia gaosiga tuai, ma ua faamoemoeina o le a faateleina atili lona taulaiga i maketi i le lumanai.

I le aso 19 o Oketopa, o le tau o le propylene glycol methyl ether acetate i totonu o le atunuu e 9800 yuan/tone. O faʻamatalaga auiliili o le propylene glycol methyl ether acetate: 200 kg/paelo 99.9% o loʻo iai le tulaga faʻaleatunuu. E aoga le ofo mo le 1 aso. O le kamupani e tuʻuina atu le tau: Xiamen Xiangde Supreme Chemical Products Co., LTD.

I le taimi nei, faatasi ai ma le atinaʻeina o le valiina, vaitusi, lolomi ma le valiina, ie ma isi alamanuia i Saina, o loʻo faʻatupulaʻia le manaʻoga o le maketi mo le alamanuia o le propylene glycol methyl ether acetate a Saina, ma o loʻo faʻateleina pea le fua faatatau o le gaosiga i totonu o le atunuʻu o le propylene glycol methyl ether acetate alamanuia. Peitaʻi, o le tekinolosi gaosiga o le eletise ma e oʻo lava i le semiconductor grade propylene glycol methyl ether acetate e fai si faigata. I le taimi nei, o pisinisi a Saina i le lotoifale o le propylene glycol methyl ether acetate e tele atu le avanoa e sui ai maketi faʻaulufale mai i lenei matata. O le eletise grade propylene glycol methyl ether ma le propylene glycol methyl ether acetate e mafai ona faʻaaogaina o se vai faʻamama, vai faʻamama poʻo se vai e aveese ai le vali mo le gaosiga o vaega eletise e aofia ai semiconductors, substrates photoresist, ipu uʻamea, vai tioata ma isi matata. Talu ai nei na faʻalauiloa mai ai e Saina ni fuafuaga "sefulu ma le fa" e faʻamalosia ai le atinaʻeina o semiconductor ma isi alamanuia o mea faʻatekonolosi maualuga, o le alamanuia propylene glycol methyl ether acetate a Saina poʻo le a mafai ona ave le matagi sasaʻe o le faiga faʻavae, faʻateleina le atinaʻeina ma le faʻalauteleina o le eletise propylene glycol methyl ether acetate, faʻatasi ai ma le faʻateleina o le suiga o oloa faʻaulufale mai i totonu o le atunuʻu i le lumanaʻi, o le a faʻatupuina e le alamanuia eletise propylene glycol methyl ether acetate a Saina le tele o avanoa mo tupe mama mo le alamanuia, faʻatasi ai ma le taua tele o tupe teufaafaigaluega.
