① Ọtụtụ plastik bụ ìhè na arọ, chemically kwụsiri ike, na agaghị nchara;
② Mmetụta mmetụta dị mma;
③Ọ nwere ezigbo nghọta na iyi mgbochi;
④ Ihe mkpuchi dị mma na ikuku okpomọkụ dị ala;
⑤ General formability, ezigbo colorability, obere nhazi ego;
⑥ Ọtụtụ plastics nwere ogbenye okpomọkụ na-eguzogide, elu thermal mgbasa ọnụego na mfe ọkụ;
⑦ Nkwụsi ike akụkụ na-adịghị mma na nrụrụ dị mfe;
⑧ Ọtụtụ plastik na-enwe mmetụta na-adịghị mma nke na-adịghị ala ala ma na-agbaji na obere okpomọkụ;
⑨ Mfe afọ;
⑩ Ụfọdụ plastik na-adị mfe mgbaze na ihe mgbaze.
Enwere ike kewaa plastik ụzọ abụọ: thermosetting na thermoplastic. Enweghị ike ịmegharị nke mbụ ma jiri ya mee ihe, enwere ike ịmepụta nke ikpeazụ ugboro ugboro. E nwere ụdị abụọ nke ihe owuwu nke polymers plastik:
Nke mbụ bụ usoro nhazi, na ngwakọta polymer nwere ihe owuwu a ka a na-akpọ ogige polymer linear;
Nke abụọ bụ ụdị ụdị ahụ, na ngwakọta polymer nwere ihe owuwu a ka a na-akpọ ogige ahụ ụdị ahụ.
Ụfọdụ ndị polymer nwere eriri alaka, nke a na-akpọ polymers alaka, nke bụ nke usoro ahịrị. Ọ bụ ezie na ụfọdụ polymers nwere njikọ dị n’etiti ụmụ irighiri ihe, ha na-enwechaghị njikọ, nke a na-akpọ nhazi netwọk ma bụrụ nke usoro ahụ. Ihe owuwu abụọ dị iche iche, na-egosi ihe abụọ dị iche. Usoro ahịrị ahịrị (gụnyere alaka alaka) polymers nwere njirimara nke ngbanwe na plasticity n’ihi ịdị adị nke ụmụ irighiri ihe ndị nwere onwe ha, nke nwere ike ịgbaze na ihe mgbaze, nwere ike ịgbaze site na kpo oku, ma nwee obere ike na brittleness. Ebe ọ bụ na enweghị macromolecules nọọrọ onwe ya, polymer nke yiri ahụ enweghị ike na-agbanwe agbanwe na plasticity, enweghị ike igbari ma gbazee, mana ọ nwere ike ịza, ma nwee nnukwu ike na brittleness. Plastics nwere ihe owuwu abụọ nke polymers, thermoplastics emere nke polymers linear, na plastik thermosetting nke ejiri nnukwu polymers mee.
