Izinto zokusetshenziswa zepulasitiki ziqinile noma i-elastomeric ezingeni lokushisa legumbi, futhi izinto zokusetshenziswa ziyashisiswa ngesikhathi sokucubungula ukuze zibe uketshezi oluncibilikisiwe. Amapulasitiki angahlukaniswa abe "thermoplastics" kanye "nama-thermosets" ngokusho kwezici zabo zokucubungula.
"I-Thermoplastics" ingashiswa futhi yenziwe izikhathi eziningi futhi ingaphinda isetshenziswe kabusha. Ziwuketshezi njenge-slime futhi zinesimo sokuncibilika kancane. Ama-thermoplastic asetshenziswa kakhulu yi-PE, PP, PVC, ABS, njll. Ama-thermosets aqina unomphela lapho ishiswa futhi selehlile. Iketango lamangqamuzana lakha izibopho zamakhemikhali futhi liba isakhiwo esizinzile, ngakho ngisho noma liphinde lishiswe, alikwazi ukufinyelela esimweni soketshezi oluncibilikisiwe. Ama-epoxies nama-rubber ayizibonelo zamapulasitiki we-thermoset.
Okulandelayo ezinye izinhlobo ezivamile kanye nemininingwane yezinqubo zokucutshungulwa kwepulasitiki: ukubunjwa kwepulasitiki (ukubunjwa kokuwisa, ukubumba ukubumbana, ukubumba okujikelezayo), ukubunjwa kokushaywa, i-plastic extrusion, i-plastic thermoforming (i-compression molding, i-vacuum forming), ukubumba umjovo wepulasitiki, i-plastic Welding (ukungqubuzana i-welding, i-laser welding), i-plastic foaming
