SIS (Styrene-isoprene-styrene block copolymer)
Baling Petrochemical SIS bụ styrene - isoprene block copolymer n'ụdị nke ọcha porous urughuru ma ọ bụ translucent kọmpat urughuru, na atụmatụ nke ọma thermo-plasticity, elu elasticity, ọma gbazee fluidity, ezi ndakọrịta na tackifying resin, nchekwa na-adịghị egbu egbu.Enwere ike itinye ya na nrapado na-ekpo ọkụ na-agbaze, simenti ihe mgbaze, mpempe akwụkwọ na-agbanwe agbanwe, plastik na mgbanwe asphalt, ọ bụkwa ezigbo ngwa ngwa nke adhesives eji emepụta akpa nkwakọba, ihe ndozi, teepu nrapado nwere akụkụ abụọ na akara. .
ALA NA ngwa
Styrene-isoprene block copolymers (SIS) bụ nnukwu olu, ọnụ ala azụmahịa thermoplastic elastomers (TPE) nke a na-emepụta site na ndụ ionic copolymerization site n'usoro ewebata styrene, 2-methyl-1,3-butadiene (isoprene), na styrene n'ime reactor. .Ọdịnaya styrene na-adịkarị n'etiti 15 na 40 pasent.Mgbe ọ dị jụụ n'okpuru ebe mgbaze, SIS nwere obere ọdịnaya styrene dị ala-iche n'ime oghere polystyrene nwere nano nke etinyere na matriks isoprene ebe mmụba nke ọdịnaya styrene na-eduga na cylindrical wee banye n'ihe owuwu lamellar.Ngalaba styrene siri ike na-arụ ọrụ dị ka crosslinks anụ ahụ nke na-enye ike arụ ọrụ ma melite nguzogide abrasion, ebe matriks roba isoprene na-enye mgbanwe na ike.Njirimara igwe nke SIS elastomers nwere ọdịnaya styrene dị ala yiri nke rọba vulcanized.Agbanyeghị, n'adịghị ka rọba vulcanized, SIS elastomers nwere ike iji akụrụngwa eji arụpụta polymers thermoplastic.
A na-ejikọta SIS ngọngọ copolymers na tackifier resins, mmanụ na ihe ndị na-ejuputa, nke na-enye ohere maka mgbanwe mgbanwe nke ngwaahịa ngwaahịa ma ọ bụ tinye ha na polymers thermoplastic ndị ọzọ iji kwalite arụmọrụ ha.
A na-eji SIS copolymer eme ihe n'ọtụtụ ebe na nrapado hotmelt, ihe mkpuchi, ihe gasket, eriri rọba, ngwaahịa ihe egwuregwu ụmụaka, akpụkpọ ụkwụ akpụkpọ ụkwụ na ngwaahịa bitumen maka ịkwanye okporo ụzọ na ngwa mkpuchi ụlọ.A na-ejikwa ha dị ka ndị na-eme mgbanwe mmetụta na ndị na-esi ike na plastik na (nhazi) nrapado.
