MBS n'onwe ya nwere ezigbo arụmọrụ mmetụta, nghọta dị mma, na nnyefe nke ihe karịrị 90%. Ọ bụ ezie na ọ na-eme ka arụmọrụ mmetụta dịkwuo mma, ọ naghị enwe mmetụta dị ukwuu na ihe ndị ọzọ nke resin, dị ka ike nrụgide na ogologo oge na nkwụsị. MBS dị oke ọnụ ma a na-ejikarị ya na njikọta ya na ihe ndị ọzọ na-agbanwe mmetụta dịka EAV, CPE, SBS, wdg. MBS enweghị ike iguzogide okpomọkụ na iguzogide ihu igwe, na-eme ka ọ ghara ịdị mma maka ojiji n'èzí ogologo oge. A naghị eji ya eme ihe dị ka ihe na-agbanwe mmetụta n'imepụta profaịlụ ọnụ ụzọ plastik na windo.
(4) SBS
SBS bụ otu n'ime ihe ndị na-eme ka ihe dị n'ime sterrene, butadiene, na styrene, nke a makwaara dịka thermoplastic styrene butadiene roba. Ọ bụ nke thermoplastic elastomers, a pụkwara ikewa nhazi ya n'ụdị abụọ: nke yiri kpakpando na nke dị larịị. Oke nke styrene na butadiene na SBS bụkarị 30/70, 40/60, 28/72, na 48/52. A na-ejikarị ya eme ihe dị ka ihe na-agbanwe mmetụta maka HDPE, PP, na PS, yana usoro nke akụkụ 5-15. Isi ọrụ nke SBS bụ ime ka ihe na-eguzogide mmetụta ya dị ala. SBS enweghị ike iguzogide ihu igwe nke ọma, ọ dịghịkwa mma maka ngwaahịa ojiji n'èzí ogologo oge.
(5) ABS
ABS bụ ternary copolymer nke styrene (40% -50%), butadiene (25% -30%), na acrylonitrile (25% -30%), nke a na-ejikarị eme ihe dị ka plastik injinia ma a na-ejikwa ya eme ihe maka mgbanwe mmetụta PVC, yana ezigbo mmetụta mgbanwe mmetụta okpomọkụ dị ala. Mgbe ọnụọgụ ABS agbakwunyere ruru akụkụ 50, ike mmetụta nke PVC nwere ike ịdị ka nke ABS dị ọcha. Ọnụọgụ ABS agbakwunyere na-abụkarị akụkụ 5-20. ABS enweghị ike iguzogide ihu igwe na-adịghị mma ma ọ dabara adaba maka ojiji n'èzí ogologo oge na ngwaahịa. A naghị eji ya dị ka ihe na-agbanwe mmetụta na mmepụta nke profaịlụ ọnụ ụzọ na windo plastik.
