ʻO ka ʻenekinia plastics he pūʻulu o nā mea ʻilika i ʻoi aku ka maikaʻi o ka mīkini a/a i ʻole nā ​​mea wela ma mua o nā plastik waiwai i hoʻohana nui ʻia (e like me ka polystyrene, PVC, polypropylene a me polyethylene).

ʻOi aku ke kumukūʻai, hana ʻia nā plastik ʻenekinia ma ka liʻiliʻi a hoʻohana ʻia no nā mea liʻiliʻi a i ʻole nā ​​noi haʻahaʻa haʻahaʻa (e like me nā ʻāpana mechanical), ma mua o ka nui a me nā hopena kiʻekiʻe (e like me nā ipu a me ka pahu).
ʻO ka huaʻōlelo maʻamau e pili ana i nā mea thermoplastic ma mua o nā mea thermosetting.ʻO nā hiʻohiʻona o nā plastik ʻenekinia he acrylonitrile butadiene styrene (ABS), i hoʻohana ʻia no nā bumper kaʻa, ʻoki dashboard a me nā pōhaku Lego;polycarbonates, hoʻohana ʻia i nā mahiole kaʻa a me nā disc optical;a me nā polyamides (nylons), i hoʻohana ʻia no ka ski a me nā kāmaʻa ski.

Ua hoʻololi mālie nā ʻenekinia i nā mea ʻenekinia kuʻuna e like me ka lāʻau a i ʻole metala i nā noi he nui.Ma waho aʻe o ka hoʻohālikelike ʻana a i ʻole ka hoʻonui ʻana iā lākou i ke kaumaha/ikaika a me nā waiwai ʻē aʻe, ʻoi aku ka maʻalahi o ka hana ʻana i nā plastics engineering, ʻoi aku ka paʻakikī.
