Njirimara nke Plastics

Plastics na-abụkarị ihe siri ike.Ha nwere ike ịbụ amorphous, crystalline, ma ọ bụ ọkara kristal siri ike (crystallites).
Plastics na-abụkarị ndị na-eduzi ọkụ na ọkụ adịghị mma.Ọtụtụ bụ ndị insulators dielectrically siri ike.
Ndị polima nwere iko na-esikarị ike (dịka ọmụmaatụ, polystyrene).N'aka nke ọzọ, enwere ike iji mpempe akwụkwọ dị nro nke polymers dị ka ihe nkiri (dịka ọmụmaatụ, polyethylene).
Mgbe nrụgide siri ike, ihe fọrọ nke nta ka ọ bụrụ plastik niile na-egosipụta elongation nke na-adịghị agbake mgbe ewepụrụ nrụgide ahụ.A na-akpọ nke a "creep."
Plastics na-adịte aka ma na-eweda ya obere oge.
