Chipurasitiki chinhu chemupolymer (macromolecule) iyo inowedzeredzwa nekuwedzera polymerization kana polycondensation reaction nema monomers kunge mbishi zvigadzirwa. Yayo anti-deformation kugona kuri pakati. Icho chiri pakati pefiber uye rubber. Iyo inoumbwa neyakagadzirwa resin uye mafirita, mapurasitiki, uye zvinodzikamisa. Iyo inoumbwa neyekuwedzera senge vamiririri, mafuta ekuzora, uye pigments.
Chinhu chikuru chepurasitiki ibwe. Resin inoreva chinhu chinogadziriswa chemupolymer chisina kusanganiswa nezvakawedzerwa zvakasiyana. Izwi resin raitumidzwa zita rekuti lipids yakavanzika nezvirimwa nemhuka, senge rosin uye shellac. Iyo resin inosvika 40% kusvika 100% yehuremu hwese hwepurasitiki. Izvo zvakakosha zveplastics zvinonyanya kutemerwa nemhando yeiyo resin, asi zvinowedzerwa zvakare zvinoita basa rakakosha. Mamwe mapurasitiki akanyatsogadzirwa nema synthetic resin, pasina kana zvidiki zvekuwedzera, senge plexiglass, polystyrene, nezvimwe.
