Yayin da yake inganta aikin tasiri, ba shi da tasiri sosai akan sauran kaddarorin resin, kamar ƙarfin tauri da tsawaitawa a lokacin karyewa. MBS yana da tsada kuma galibi ana amfani da shi tare da wasu masu gyara tasiri kamar EAV, CPE, SBS, da sauransu. MBS yana da ƙarancin juriyar zafi da juriyar yanayi, wanda hakan ya sa bai dace da amfani da shi a waje na dogon lokaci ba. Ba a amfani da shi gabaɗaya azaman mai gyara tasirin tasiri wajen samar da bayanan ƙofofi da tagogi na filastik.
(4) SBS
SBS wani nau'in roba ne mai kama da styrene, butadiene, da styrene, wanda kuma aka sani da robar thermoplastic styrene butadiene. Yana cikin robar thermoplastic elastomers kuma tsarinsa za a iya raba shi zuwa nau'i biyu: siffar tauraro da layi. Rabon styrene da butadiene a cikin SBS galibi shine 30/70, 40/60, 28/72, da 48/52. Ana amfani da shi galibi azaman mai gyara tasirin HDPE, PP, da PS, tare da adadin sassa 5-15. Babban aikin SBS shine inganta juriyarsa ga tasirin zafi mai ƙarancin zafi. SBS yana da mummunan juriya ga yanayi kuma bai dace da samfuran amfani da waje na dogon lokaci ba.
(5) ABS
ABS wani nau'in copolymer ne na styrene (40% -50%), butadiene (25% -30%), da acrylonitrile (25% -30%), wanda galibi ana amfani da shi azaman robobi na injiniya kuma ana amfani da shi don gyaran tasirin PVC, tare da kyakkyawan tasirin gyaran tasirin zafi mai ƙarancin zafi. Lokacin da adadin ABS da aka ƙara ya kai sassa 50, ƙarfin tasirin PVC na iya zama daidai da na ABS mai tsabta. Adadin ABS da aka ƙara gabaɗaya sassa 5-20 ne. ABS ba shi da juriya ga yanayi kuma bai dace da amfani da shi a waje na dogon lokaci a cikin samfura ba. Ba a amfani da shi azaman mai gyara tasiri wajen samar da bayanan ƙofofi da taga na filastik.
(6) EVA
EVA copolymer ne na ethylene da vinyl acetate, kuma gabatar da vinyl acetate yana canza yanayin lu'ulu'u na polyethylene. Abubuwan da ke cikin vinyl acetate sun bambanta sosai, kuma ma'aunin refractive na EVA da PVC ya bambanta, wanda hakan ke sa ya yi wuya a sami samfuran da ba su da haske. Saboda haka, ana amfani da EVA sau da yawa tare da sauran resins masu jure wa tasiri. Adadin EVA da aka ƙara bai wuce sassa 10 ba.
