O-mama EPDM 70shore-A FDA food grade
O-mama EPDM 70shore-A FDA food grade
● I le tulaga lautele, o le EPDM o-mama e iloa lelei le tetee atu i le ozone, susulu o le la, ma le tau, ma e lelei tele le fetuutuunai i le maualalo o le vevela, lelei le tetee atu i kemikolo (tele faʻamaʻi faʻamaʻi ma alkalis faʻapea foʻi ma polar solvents), ma le lelei o le eletise eletise.
● O-mama EPDM e mafai foi ona oʻo mai i se uʻamea e mafai ona iloa suiga aʻo faʻatumauina uiga tutusa e pei o le EPDM o-mama lautele.EPDM o-mama e masani ona lanu uliuli, faʻatasi ai ma se faʻaola umi. Faiga Faʻamalolo: Peroxide-Cured Standard EPDM o-mama faʻapipiʻi e masani ona faʻamalolo le sulfur.
● Sulfur-cured compounds ofo atu mea e sili atu ona fetuutuunai ae e sili atu ona faigofie i le faʻamaʻaʻaina ma maua ai se faʻapipiʻi maualalo faʻapipiʻi ma le maualuga o le vevela.Peroxide-cured EPDM o-mama faʻapipiʻi e sili atu le vevela vevela ma se seti faʻapipiʻi maualalo. E ogatasi ma le faʻaaogaina umi, aemaise lava mo faʻaoga faʻapipiʻi i le fale faufale, ae e sili atu le taugata ma sili atu ona faigata mo le gaosiga o le EMsulfur.
● Mo nisi faʻamatalaga i le EPDM cure systems, faʻamolemole faʻafesoʻotaʻi matou mo faʻamatalaga faʻamatalaga.
● EPDM O-Ring Temperature Range: Standard Low Temp: -55°C (-67°F)
● Tulaga Maualuluga Temp: 125°C (257°F) Fa'atino Lelei I totonu: Alcohols Suavai taofi ta'avale Ketones Fa'amama vai ma alkali Suau'u sili ma ga'o Ausa e o'o i le 204.4ºC (400ºF) Suavai Fosfat ester fa'avae sua oona Osone, matua, ma le tau.
● o le a le isi mea, EPM o se Copolymer o ethylene ma propylene. O le EPDM o se terpolymer o le ethylene ma le propylene ma sina vaega itiiti o le tolu monomer (e masani lava o le diolefin) e faʻatagaina ai le faʻamaʻiina i le sulfur.
● E masani lava o le Ethylene Propylene Rubber o loʻo i ai le teteʻe lelei i le osone, susulu o le la ma le tau, ma e lelei tele le fetuutuunai i le maualalo o le vevela, lelei le faʻamaʻiina o vailaʻau (tele acids dilute, alkalis & polar solvents), ma mea lelei faʻamalo eletise.
● Shore-A:Mai le 30-90 matafaga-A soʻo se lanu e mafai ona fai.
● LAITI:AS-568 lapopoa uma.
