HPMC E 50
Ko te EipponCellHPMC E 50 Hydroxypropyl methylcellulose he momo marara nui e whakamahia ana i roto i te umanga polyvinyl chloride (PVC).Ka whakamahia i te wa o te polymerization whakatārewatanga o te vinyl chloride ki te whakaiti i te awangawanga atanga i waenga i te vinyl chloride monomer (VCM) me te wai.Ko te whakahekenga o te taumahatanga ka awhina i te whakamararatanga o te VCM ki roto i te kaupapa wai.I tua atu, he awhina ki te aukati i te hanumitanga o nga maturuturunga iho o te VCM i te tiimatanga o te tukanga polymerization me te aukati i te whakakotahitanga i waenga i nga matūriki polymer i roto i nga waahanga takawaenga me o muri mai.I roto i te punaha polymerization whakatārewatanga, ko te EipponCellHPMC E 50 Hydroxypropyl methylcellulose he kaupapa rua mo te whakamararatanga me te whakamarumaru.

HPMC F 50
Ko te EipponCellHPMC F 50, he hydroxypropyl methyl cellulose, e mahi ana hei dispersant i roto i te ahumahi PVC.I roto i te tukanga polymerization whakatārewatanga o vinyl pūhaumāota, te nuinga whakamahia dispersants ngā pūhui waerau pērā i polyvinyl waipiro me te cellulose etera.I te wa e whakakorikoria ana, ka ngawari te hanga o nga pata me nga rahi e tika ana.Ko tenei kaha ka kiia ko te kaha marara o te dispersant.I tua atu, ka whakauruhia te dispersant ki runga i te mata o te vinyl chloride monomer droplets, ka hanga he paparanga whakamarumaru hei aukati i te whakahiatotanga o te maturuturu me te whakapumau.E mohiotia ana tenei paanga ko te kaha pupuri colloid o te dispersant.
