Low density Polyethylene Film Grade QLT04 QLF39
Low-density polyethylene (LDPE) o se resini gaosia e fa'aogaina ai le fa'agasologa o le mamafa e ala i le polymerization free radical o le ethylene ma o lea e ta'ua ai fo'i o le "high-pressure polyethylene".Talu ai ona o lona filifili mole e tele lala uumi ma pupuu, o le LDPE e itiiti ifo le tioata nai lo le polyethylene maualuga (HDPE) ma o lona mamafa e maualalo.O lo'o fa'aalia ai le mama, fetu'utu'una'i, lelei le fa'a'aisa ma le a'afiaga.LDPE e mautu fa'a kemikolo.E lelei le tete'e atu i acids (vagana ai le malosi oxidizing acids), alkali, masima, mea e sili ona lelei insulation eletise.E maualalo lona sao i totonu.LDPE e maualuga le suavai ma lelei le fa'agaioiina.E talafeagai mo le faʻaaogaina i ituaiga uma o faʻagasologa o le thermoplastic, e pei o le tui tui, faʻapipiʻiina, faʻafefeteina, rotomolding, faʻapipiʻiina, faʻafefe, thermoforming, vevela-jet uelo ma le faʻafefe.
Fa'atatauga
O le LDPE ata tifaga e masani ona faʻaaogaina i le gaosiga o le faʻapipiʻiina o ata tifaga, ata faʻatoʻaga ma e mafai ona faʻafefiloi ma le laina maualalo-density polyethylene (LLDPE) e maua ai le PE ua suia.E le gata i lea, e mafai ona faʻaaogaina mo le vevela faʻafefete faʻapipiʻi ata, laminated film, freezing film, medical packaging, multi-layer coextrusion film, mamafa-tiute afifiina ata, paipa paipa, cable sheathing, lining and high-end chemical foaming.
O le LDPE (QLT04/QLF39) o se mea e sili ona lelei le fa'apipi'iina o ata.

Paketi, Teuina ma Felauaiga
O le resini o lo'o fa'apipi'iina i totonu o taga lalaga polypropylene e fa'apipi'iina ata.Ole mamafa ole 25Kg/pe.O le resini e tatau ona teuina i totonu o se fale teu oloa matutu ma mamao ese mai le afi ma le susulu o le la.E le tatau ona faaputuputu i luga o le ea.I le taimi o felauaiga, e le tatau ona faʻaalia le oloa ile susulu malosi o le la poʻo le timu ma e le tatau ona feaveaʻi faʻatasi ma le oneone, palapala, uamea, koale poʻo tioata.O felauaiga faʻatasi ma mea oona, pala ma mu e matua faʻasaina.
