Epoxidized Polybutadiene (EPB)
O le EPB o se vaega epoxy ua fa'aofiina i totonu o le filifili molecular PB, lea e iai ona lelei o le tete'e atu i le suāuu, tete'e atu i le matua, manino lelei, maualalo le fa'atinoga o le vevela, ma isi mea fa'apena. O le vaega epoxy i le filifili molecular o se vaega tali atu, lea e mafai ona fa'amalolo i le tele o isocyanates ma epoxy curing agents.
O le polymer ua fa'amālōlōina e iai ona meatotino fa'aletino ma fa'akemikolo lelei, malosi tele le pipii i u'amea ma tioata ma isi mea e le o ni u'amea, meatotino dielectric lelei, fua fa'atatau maualalo o le fa'aitiitia, ma'a'a maualuga, mautu i le alkali ma le tele o voluma, lea e mafai ona fa'aleleia atili ai meatotino fa'amasini, malosi le pipii ma le tete'e atu i le vevela o mea polyurethane.
E faʻaleleia e vaega polar ia meatotino faʻapipiʻi o le oloa ma mea uʻamea ma mea e le o ni uʻamea; E mafai ona faʻaaogaina i mea faʻapipiʻi, faʻamaufaʻailoga, ufiufi, faʻamalosi epoxy resin, polyurethane elastomers, ma isi.
Fa'aputuina i le 50kg/talipalau, 170kg/talipalau, O le vaitaimi e teu ai e 1 tausaga.
Fa'atonuga mo le saogalemu:
E tatau ona teuina i se nofoaga malūlū, mago ma lelei mo le ea. O le tulaga sili ona lelei o le -20 ~ 38℃. E 12 masina le umi e teu ai, afai e uma le aso, e mafai ona faʻaaogaina pe afai e tusa ai ma tulaga masani ma toe faia se suʻega. A o felauaiga e tatau ona ʻaloʻese mai le timu ma le susulu o le la. Aua neʻi faʻafefiloi ma se vailaʻau faʻaola malosi.
