Izinto eziqhelekileyo zeplastiki:
Iplastiki esetyenziswa ngokuqhelekileyo ayiyonxalenye enye, yenziwe kwizinto ezininzi.Phakathi kwazo, iipolymers eziphezulu ze-molecular (okanye i-synthetic resins) zizinto eziphambili zeeplastiki.Ukongezelela, ukwenzela ukuba kuphuculwe ukusebenza kweeplastiki, izinto ezahlukeneyo ezincedisayo, ezifana nokuzalisa, iiplastiki, i-lubricant, kunye nezizinzi, kufuneka zongezwe kwii-molecular compounds., Imibala, i-antistatic agents, njl., ingaba yiplastiki kunye nokusebenza kakuhle.
Izongezo zePlastiki, ezikwabizwa ngokuba zizongezo zeplastiki, ziikhompawundi ekufuneka zongezwe ukuphucula ukusebenza kwepolymer (synthetic resin) okanye ukuphucula ukusebenza kweresin ngokwayo xa i-polymer (synthetic resin) isenziwa.Ngokomzekelo, ukwenzela ukunciphisa ukushisa kwe-polyvinyl chloride resin, i-plasticizer yongezwa ukwenza imveliso ithambile;omnye umzekelo kukongeza i-agent ekhupha ugwebu ukulungiselela ukulungiswa kwe-lightweight, i-vibration-resistant, i-heat-insulating, kunye ne-foam-insulating-insulating;Iqondo lokushisa lokubola lisondele kakhulu kwiqondo lokushisa lokubumba, kwaye ukubumba akunakufezekiswa ngaphandle kokongeza izinzisi zokushisa.Ke ngoko, izongezo zeplastiki zithatha indawo ebaluleke kakhulu ekusetyenzweni kweplastiki.
Iiplastiki ziikhompawundi zepolymer (i-macromolecules), ezaziwa ngokuba ziiplastiki okanye iintlaka, ezipholima zii-monomers njengezinto ezikrwada ngokudibanisa i-polymerization okanye i-polycondensation reactions.Ukubunjwa kunye nokumila kunokutshintshwa ngokukhululekileyo.Iqulethwe ngeerasi zokwenziwa kunye nezihluzi.I-Plasticizer, i-stabilizer, i-lubricant, i-pigment kunye nezinye izongezo.
