MBS ke copolymer ea li-monomers tse tharo: methyl methacrylate, butadiene, le styrene. The solubility parameter ea MBS e pakeng tsa 94 le 9.5, e leng haufi le parameter ea solubility ea PVC. Ka hona, e lumellana hantle le PVC. Ntho ea eona e kholo ka ho fetisisa ke hore ka mor'a ho eketsa PVC, e ka etsoa sehlahisoa se hlakileng. Ka kakaretso, ho kenyelletsa likarolo tse 10-17 ho PVC ho ka eketsa matla a eona a ts'usumetso ka makhetlo a 6-15. Leha ho le joalo, ha palo ea MBS e ekelitsoeng e feta likarolo tse 30, matla a tšusumetso ea PVC a hlile a fokotseha. MBS ka boeona e na le ts'ebetso e ntle ea ts'ebetso, ponaletso e ntle, le phetisetso e fetang 90%. Ha e ntse e ntlafatsa ts'ebetso ea ts'ebetso, e na le phello e fokolang ho thepa e 'ngoe ea resin, joalo ka matla a thata le bolelele nakong ea khefu. MBS e theko e boima 'me e atisa ho sebelisoa hammoho le liphetoho tse ling tsa tšusumetso tse kang EAV, CPE, SBS, joalo-joalo MBS e na le mocheso o fokolang oa mocheso le ho hanyetsa boemo ba leholimo, ho etsa hore e se ke ea tšoaneleha bakeng sa tšebeliso ea nako e telele ea ka ntle. Ka kakaretso ha e sebelisoe e le phetoho ea tšusumetso tlhahisong ea li-profiles tsa mamati a polasetiki le lifensetere.
(4) SBS
SBS ke ternary block copolymer ea styrene, butadiene, le styrene, e tsejoang hape e le rabara ea thermoplastic styrene butadiene. Ke ea li-elastomers tsa thermoplastic mme sebopeho sa eona se ka aroloa ka mefuta e 'meli: sebopeho sa naleli le mola. Karolelano ea styrene ho butadiene ho SBS ke haholo-holo 30/70, 40/60, 28/72, le 48/52. Haholo-holo e sebelisoa e le phetoho ea tšusumetso bakeng sa HDPE, PP, le PS, e nang le litekanyetso tsa likarolo tse 5-15. Mosebetsi o ka sehloohong oa SBS ke ho ntlafatsa matla a eona a ho hanyetsa mocheso o tlase. SBS e na le khanyetso e mpe ea boemo ba leholimo 'me ha e loketse lihlahisoa tsa nako e telele tsa ts'ebeliso ea kantle.
(5) ABS
ABS ke ternary copolymer ea styrene (40% -50%), butadiene (25% -30%), le acrylonitrile (25% -30%), haholo-holo e sebelisoang e le lipolasetiki tsa boenjiniere 'me e boetse e sebelisoa bakeng sa phetoho ea tšusumetso ea PVC, ka tlaase e ntle. - liphello tsa phetoho ea mocheso. Ha palo ea ABS e ekelitsoeng e fihla likarolong tse 50, matla a PVC a ka lekana le a ABS e hloekileng. Palo ea ABS e kenyellelitsoeng hangata ke likarolo tse 5-20. ABS e na le khanyetso e mpe ea boemo ba leholimo 'me ha ea lokela ho sebelisoa ka ntle nako e telele lihlahisoa. Ka kakaretso ha e sebelisoe e le phetoho ea tšusumetso tlhahisong ea li-profiles tsa mamati a polasetiki le lifensetere.
(6) EVA
EVA ke copolymer ea ethylene le vinyl acetate, 'me kenyelletso ea vinyl acetate e fetola crystallinity ea polyethylene. Likahare tsa vinyl acetate li fapane haholo, 'me index ea refractive ea EVA le PVC e fapane, e etsa hore ho be thata ho fumana lihlahisoa tse pepeneneng. Ka hona, hangata EVA e sebelisoa hammoho le li-resin tse ling tse hanyetsanang le tšusumetso. Palo ea EVA e kenyellelitsoeng e ka tlase ho likarolo tse 10.
