SIS(Styrene-isoprene-styrene block copolymer)
NĀ WAIWAI A ME NĀ PALAPALA ʻO Styrene-isoprene block copolymers (SIS) he leo nui, haʻahaʻa kumu kūʻai thermoplastic elastomers (TPE) i hana ʻia e ola ionic copolymerization ma o ka hoʻokomo ʻana i ka styrene, 2-methyl-1,3-butadiene (isoprene), a me styrene. i loko o ka reactor.ʻOkoʻa ka maʻiʻo styrene ma waena o 15 a 40 pakeneka.Ke hoʻoluʻu ʻia ma lalo o ka helu hoʻoheheʻe, ʻo SIS me kahi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i hoʻokaʻawale ʻia i loko o nā ʻāpana polystyrene nano-nui i hoʻokomo ʻia i loko o kahi ... -
SEBS(Styrene Ethylene Butylene Styrene)
NĀ WAIWAI A ME NA PALAPALA ʻO Styrene-ethylene-butylene-styrene, i kapa ʻia hoʻi ʻo SEBS, he thermoplastic elastomer (TPE) koʻikoʻi e like me ka ʻōpala me ka ʻole o ka vulcanization.Ua hana ia e ka hapa a me ka wae hydrogenating o styrene-butadiene-styrene copolymer (SBS) e hoʻomaikaʻi i ka thermal stability, weathering a me ka aila kū'ē, a hana SEBS mahu sterilisable.Naʻe, hy ... -
SBS (styrene –butadiene block copolymer)
NA WAIWAI A ME NA PALAPALA 'O Styrene-butadiene block copolymers kekahi papa ko'iko'i o na lapepa synthetic.ʻO nā ʻano mea maʻamau ʻelua he linear a me radial triblock copolymers i loaʻa nā poloka waena a me nā poloka hope polystyrene.Hoʻohui nā elastomers SBS i nā waiwai o kahi resins thermoplastic me nā waiwai o ka rubber butadiene.ʻO nā poloka styrene paʻakikī, hāʻawi i ka ikaika mechanical a hoʻomaikaʻi i ka pale ʻana i ka abrasion, aʻo ka pahu waena waena e hāʻawi i ka maʻalahi a me ka paʻakikī.I ka m...
