SIS(Styrene-isoprene-styrene block copolymer)
ZINTHU NDI NTCHITO Styrene-isoprene block copolymers (SIS) ndi voliyumu yayikulu, yotsika mtengo yamalonda ya thermoplastic elastomers (TPE) yomwe imapangidwa ndi moyo ionic copolymerization poyambitsa sequentially styrene, 2-methyl-1,3-butadiene (isoprene), ndi styrene. mu riyakitala.Zomwe zili mu styrene nthawi zambiri zimasiyana pakati pa 15 ndi 40 peresenti.Ikazizira pansi pa malo osungunuka, ma SIS okhala ndi ma styrene otsika pang'ono-osiyanitsidwa kukhala ma nano-size polystyrene spheres ophatikizidwa mu ... -
SEBS(Styrene Ethylene Butylene Styrene)
ZOCHITIKA NDI ZOTHANDIZA Styrene-ethylene-butylene-styrene, yomwe imadziwikanso kuti SEBS, ndi yofunika kwambiri ya thermoplastic elastomer (TPE) yomwe imakhala ngati mphira popanda vulcanization.SEBS ndi yamphamvu komanso yosinthika, imakhala ndi kutentha kwambiri komanso kukana kwa UV ndipo ndi yosavuta kuikonza.Imapangidwa ndi hydrogenating pang'ono komanso yosankha ya styrene-butadiene-styrene copolymer (SBS) yomwe imathandizira kukhazikika kwamafuta, kutentha kwanyengo komanso kukana kwamafuta, ndikupangitsa kuti SEBS ikhale yosakhazikika. -
SBS(styrene-butadiene block copolymer)
ZINTHU NDI NTCHITO Styrene-butadiene block copolymers ndi gulu lofunika la mphira kupanga.Mitundu iwiri yodziwika kwambiri ndi ma linear ndi ma radial triblock copolymers okhala ndi midadada pakati pa mphira ndi midadada yomaliza ya polystyrene.Ma elastomer a SBS amaphatikiza zinthu za utomoni wa thermoplastic ndi wa rabara wa butadiene.Mipiringidzo yolimba, yagalasi ya styrene imapereka mphamvu zamakina ndikuwongolera kukana kwa abrasion, pomwe mphira wapakati pa block amapereka kusinthasintha komanso kulimba.Mu m...
