O lenei oloa o le HPMC vasega alamanuia, e masani ona faʻaaogaina e avea ma sui faʻasalalau mo le gaosiga o le PVC mae pei o le fesoasoani autu o loʻo faʻaaogaina i le gaosia o le PVC suspension polymerization, e faʻaaogaina foi e pei o le mafiafia,fa'amautu, emulsifier, mea fa'apitoa, vai fa'atumauina le sui, ma sui fai ata ma isi mea i le gaosiga.petrochemicals, mea faufale, vali vali, vailaʻau faʻatoʻaga, vaitusi,
'ie, keramika,pepa, mea teuteu ma isi oloa.I tulaga o le faʻaaogaina i le resin synthetic, e mafai ona faia le'oloa e fa'amama fa'atasi ma vaega masani, kalave fa'apitoa ma mea lelei fa'agaioiga,lea e toetoe lava suitulaga gelatin ma le polyvinyl ava malosi e pei o dispersant.O le isi faʻaoga o loʻo i totonu o le faʻagasologa o galuega faufale, aemaise lava mo le fausiaina o masini e pei o puipui fale, st.uccoing ma caulking;faʻatasi ai ma le malosi faʻapipiʻi maualuga, e mafai foʻi ona faʻaititia le sima, aemaise lava ile fausiaina o mea teuteumo le faapipiiina o tile, maamora ma palasitika trim.When faaaogaina e avea o se mafiafia i le alamanuia coatings, e mafaifaia le ufiufi susulu ma maaleale, puipuia le malosi mai le uma, ma faʻaleleia le faʻaleleia o meatotino.Pe a faʻaaogaina i le paʻu puipui, paʻu gypsum, gypsum faʻapipiʻi, ma putty e le susu, o lona taofi vaima le malosi faʻapipiʻi o le a matua faʻaleleia. E le gata i lea, e mafai foi ona faʻaaogaina i vaega e pei oceramics galue, metallurgy, mea e ufiufi ai fatu, vaitusi faʻavae, mea teuteu, eletise, lolomi.ma vali, pepa ma isi.
I le taimi o le tapenaga o faiga fa'afuainumera eseese mo lenei oloa, e mafai e le au fa'apitoa a Taixu ona tu'uina atu fa'atalanoaga fa'apitoa, su'esu'ega fa'atekinisi ma fa'ata'ita'iga umi o le faiga o fua fa'atatau.
