SEBS(Styrene Ethylene Butylene Styrene)
STYRENE-ETHYLENE-BUTYLENE-STYRENE THERMOPLASTIC ELASTOMER (SEBS)
NA WAIWAI A ME NA PONO
ʻO Styrene-ethylene-butylene-styrene, ka mea i kapa ʻia ʻo SEBS, he mea koʻikoʻi thermoplastic elastomer (TPE) e hana like me ka ʻōpala me ka ʻole o ka vulcanization.Hana ʻia ia e ka hydrogenating hapa a me ka koho o styrene-butadiene-styrene copolymer (SBS) e hoʻomaikaʻi ai i ka paʻa ʻana o ka wela, ka wā a me ka pale ʻana i ka aila, a hana i ka SEBS steam sterilisable. .
Hoʻohui pinepine ʻia nā elastomers SEBS me nā polymers ʻē aʻe e hoʻomaikaʻi i kā lākou hana.Hoʻohana ʻia lākou e like me ka hoʻololi ʻana i ka hopena no ka ʻenehana thermoplastics a ma ke ʻano he flexibilizers / tougheners no ka polypropylene māmā (PP).Hoʻohui pinepine ʻia ka aila a me nā mea hoʻopiha i ke kumukūʻai haʻahaʻa a / a i ʻole e hoʻololi hou i nā waiwai.ʻO nā noi koʻikoʻi e pili ana i nā mea hoʻopili wela wela, nā mea pāʻani, nā kapuaʻi kāmaʻa, a me nā huahana bitumen i hoʻololi ʻia e TPE no ka paʻi alanui a me nā noi hale.
ʻO Styrenics, a i ʻole styrenic block copolymers ka mea hoʻohana nui loa o nā TPE āpau.Hoʻohui maikaʻi lākou me nā mea'ē aʻe e like me nā mea hoʻopihapiha a me nā mea hoʻololi.Hōʻike ʻia ʻo SEBS (styrene-ethylene/butylene-styrene) e nā kikowaena paʻakikī a palupalu i loko o nā kaula polimer pākahi.ʻO nā poloka hope he styrene crystalline aʻo ka waena waena he mau poloka ethylene-butylene palupalu.Ma nā mahana kiʻekiʻe, palupalu kēia mau mea a lilo i wai.Ke hooluolu, hui na kaula i na poloka hope styrene e hana ana i kea kino a hoolako i ka laau e like me ka elasticity.ʻO ka Clarity a me ka ʻae FDA e hana iā SEBS i koho maikaʻi loa no nā noi kiʻekiʻe.
Hiki i ka SEBS ke hoʻomaikaʻi i ka hana ma nā mea paʻakikī a me nā mea hoʻopili ʻē aʻe.ʻO kekahi o nā noi maʻamau e pili ana i nā ʻano lipine like ʻole, nā lepili, nā plasters, nā mea hoʻopili kūkulu, nā lole lapaʻau, nā mea hoʻopaʻa, nā uhi a me nā pena hōʻailona alanui.
Hiki ke hoʻohui ʻia ʻo SEBS e hana i nā mea e hoʻomaikaʻi ai i ka paʻa, ka manaʻo, ka helehelena a me ka ʻoluʻolu o nā noi like ʻole.ʻO nā haʻuki a me nā leʻaleʻa, nā mea pāʻani, ka maʻemaʻe, ka paʻi ʻana, nā kaʻa, a me nā mea ʻenehana i hoʻoheheʻe ʻia a hoʻopau ʻia kekahi mau hiʻohiʻona maʻamau.
Hiki ke hoʻohana pū ʻia ka SEBS me nā mea hoʻopihapiha like ʻole.E hoʻohui nā mea hoʻohui i kēia mau mea hoʻopihapiha inā hoʻonui ʻia ka ʻaila ʻaila, hoʻemi ʻia ke kumu kūʻai, hoʻomaikaʻi ʻia ka manaʻo o ka ʻili, a i ʻole ka hoʻopaʻa hou ʻana ma luna o SEBS maʻemaʻe.
ʻO ka mea hoʻopihapiha maʻamau no SEBS he ʻaila.E koho ʻia kēia mau ʻaila ma muli o nā koi noi kikoʻī.ʻO ka hoʻohui ʻana i ka aila ʻala e hoʻopalupalu i nā poloka PS ma ka plasticizing e hoʻemi ana i ka paʻakikī a me nā waiwai kino.ʻO nā aila e ʻoi aku ka palupalu o nā huahana a hana pū me nā mea kōkua hoʻoponopono.ʻOi aku ka maikaʻi o nā aila paraffinic no ka mea ʻoi aku ka maikaʻi me ka poloka kikowaena EB.ʻAʻole ʻae ʻia nā ʻaila ʻala no ka mea ua komo lākou i loko a hoʻopaʻa i nā kāʻei polystyrene.
Hiki i ka SEBS ke hoʻonui i nā noi styrene kiʻekiʻe, nā kiʻiʻoniʻoni, nā ʻeke, nā kiʻi ʻoniʻoni a me ka hoʻopili ʻana.Hiki iā lākou ke hoʻomaikaʻi i ka hana o nā polyolefins no ka hoʻohana ʻana i nā mahana wela, hoʻomaikaʻi i ka mālamalama a me ka pale ʻana, a hoʻonui i ka elasticity.
