pvc resin k tau aogā 57,
PVC Resin K Taua 57-58 Fa'aaogaina mo le gaosia o le PVC Foam Board，PVC S700,
K -57 grade resin e masani ona faʻaaogaina mo tui tui ona;ona o lona umi filifili maualalo (molecular mamafa) e maualalo lona viscosity nai lo resins tau maualuga K.E maualuga atu le fulafula o le mate nai lo le K-67 resin e fesoasoani e fa'atumu ai le pa'u ma fa'afeiloa'i le susulu mai luga o le limu i le oloa.
O le Polyvinyl Chloride, e taʻua o le PVC, o se tasi o ituaiga palasitika gaosi oloa, o le gaosiga o loʻo i ai nei e lona lua i le polyethylene.Polyvinyl chloride ua faʻaaogaina lautele i alamanuia, faʻatoʻaga ma le olaga i aso uma.O le Polyvinyl chloride o se polymer compound polymerized e vinyl chloride.E vevela.Pa'epa'e po'o le pa'epa'e samasama malamalama. E solu i ketones, esters, tetrahydrofurans ma chlorinated hydrocarbons.Fa'agata fa'ama'i sili.Le lelei le mautu vevela ma le malamalama tetee, sili atu i le 100 ℃ poʻo le umi o le faʻaalia i le susulu o le la na amata ona faʻaleagaina le hydrogen chloride, e manaʻomia e le gaosiga o palasitika le faʻamautu.E lelei le insulation eletise, e le mu.
Vasega S-700e masani lava ona faʻaaogaina e gaosia ai laupepa manino, ma e mafai ona taʻavale i pepa malo ma semi-malosi mo afifi, mea fola, ata malo mo le faʻalava (mo lole afifi pepa poʻo sikaleti ata tifaga), ma isi. E mafai foi ona extruded i malo pe ata tifaga semi-malosi, laupepa, po'o se pa e le masani ona fai mo afifi.Pe mafai foi ona tui e fai sooga, valve, vaega eletise, mea faʻaoga taavale ma vaʻa.
