SEBS(Styrene Ethylene Butylene Styrene)
STYRENE-ETHYLENE-BUTYLENE-STYRENE THERMOPLASTIC ELASTOMER (SEBS)
MEATOTOGA MA FA'AGAGA
Styrene-ethylene-butylene-styrene, lea e taʻua foi o le SEBS, o se elastomer thermoplastic taua (TPE) lea e amio e pei o le paʻu e aunoa ma le faia o le vulcanization.SEBS e malosi ma fetuutuunai, e sili ona lelei le vevela ma le UV tetee ma e faigofie ona faʻagasolo.E gaosia e vaega ma filifili hydrogenating o styrene-butadiene-styrene copolymer (SBS) lea e faaleleia ai le mautu vevela, weathering ma le suauu tetee, ma faia SEBS ausa sterilisable. Ae peitai, hydrogenation faaitiitia foi le faatinoga o masini ma faateleina le tau o le polymer. .
SEBS elastomers e masani ona faʻafefiloi ma isi polymers e faʻaleleia ai a latou gaioiga.O lo'o fa'aaogaina e fai ma suiga o a'afiaga mo fa'ainisinia thermoplastics ma fa'afaileleina / malosi mo polypropylene manino (PP).E masani ona fa'aopoopo le suau'u ma fa'atumu i tau maualalo ma/po'o le toe fa'aleleia atili o meatotino.O fa'aoga taua e aofia ai mea fa'apipi'i ma'ale'ale fa'alili vevela, meata'alo, fa'avae seevae, ma mea fa'apipi'i TPE mo fa'alava o auala ma fa'aoga taualuga.
Styrenics, po'o le styrenic block copolymers e sili ona fa'aoga lautele i TPE uma.Latou te tuʻufaʻatasia lelei ma isi mea faʻapea foʻi ma faʻatumu ma faʻaleleia.SEBS (styrene-ethylene/butylene-styrene) o lo'o fa'ailogaina i vaega malo ma vaivai i totonu o manoa polymer ta'itasi.O poloka pito o styrene tioata ae o poloka ogatotonu o poloka ethylene-butylene vaivai.I le maualuga o le vevela e faamaluluina nei mea ma avea ma vai.A mālūlū, ona fa'atasi lea o manoa i poloka pito styrene e fai ai se feso'ota'iga fa'aletino ma maua ai se pa'u e pei o le elasticity.O le manino ma le faʻamaoniga a le FDA e avea ai le SEBS ma se filifiliga sili ona lelei mo talosaga maualuga.
E mafai e le SEBS ona faʻaleleia le faʻatinoga i le faʻaogaina o le mamafa ma isi mea faʻapipiʻi.O nisi o faʻaoga masani e aofia ai le tele o lipine, faʻailoga, faʻamaʻi, faʻapipiʻi faufale, laʻei faʻafomaʻi, faʻamaufaʻailoga, paʻu ma vali faʻailoga auala.
SEBS e mafai ona tuʻufaʻatasia e maua ai mea e faʻaleleia ai le pipii, lagona, foliga ma le faʻaogaina o faʻaoga eseese.Ta'aloga ma taimi paganoa, meata'alo, tumama, afifiina, ta'avale, ma mea fa'atekinisi fa'ameamea ma fa'ao'o ese o ni fa'ata'ita'iga masani.
SEBS e mafai ona faʻaogaina faʻatasi ma faʻatumu eseese.O le a fa'aopoopoina e fa'aputuga nei mea fa'atumu pe a fa'asili le su'u suau'u, fa'aitiitiga tau, fa'aleleia atili le lagona, po'o le fa'amautu fa'aopoopo e mana'omia ile SEBS mama.
Masalo o le faʻatumu masani mo SEBS o le suauʻu.O nei suauʻu o le a filifilia e faʻatatau i manaʻoga faʻapitoa.O le fa'aopoopoina o le suau'u manogi e fa'amaluluina ai poloka PS e ala i le fa'a'i'ila e fa'aitiitia ai le ma'a'a ma mea fa'aletino.O suau'u e fa'amaluluina ai oloa ma e fai fo'i ma fesoasoani mo le gaosiga.O suauu paraffinic e sili ona lelei ona e sili atu ona fetaui ma le poloka ogatotonu EB.O suau'u manogi e masani ona 'alo'ese ona e a'afia i totonu ma fa'apipi'i le vaega o le polystyrene.
E mafai e le SEBS ona faʻaleleia le faʻaogaina o le styrene maualuga, ata tifaga, ato, ata tifaga ma faʻapipiʻi faʻaaogaina.E mafai ona latou faʻaleleia le faʻatinoga o polyolefins mo le faʻaogaina i le vevela tele, faʻaleleia le manino ma le teteʻe, ma faʻaleleia le elasticity.
