Graphene imathandizira katundu wa pulasitiki pochepetsa kugwiritsa ntchito zinthu zosagwira ntchito ndi 30 peresenti.

Gerdau Graphene, kampani ya nanotechnology yomwe imapereka zidutswa zopitilira m'mafakitale, kulengeza za m'ma polymer ku polima ndalama ku São Paulo, Brazil. Graphene yatsopano-yowonjezera polymeric restin kapangidwe ka ma Propyylene (ma pp) ndi polyethylene (pe) adapangidwanso ndi zida za Brazil, ndipo pakadali pano akukumana ndi mayesero a Graphene a ku Gravil. Zinthu zatsopano za thermoplastic zopangidwa pogwiritsa ntchito izi zimakhala zolimba ndipo zimaperekanso magwiridwe antchito ambiri pomwe ndi yotsika mtengo kupanga ndi kupanga zinyalala pang'ono.
Graphene, adawona chinthu champhamvu kwambiri padziko lapansi, ndi pepala lambiri la kaboni 1 mpaka 10 lomwe limasinthidwa kuti ligwiritsidwe ntchito zosiyanasiyana ndikuwonjezera zida za mafakitale. Kuyambira kuyambira mu 2004, zowonjezera zamankhwala zoopsa, zamagetsi, zamafuta ndi makina achita chidwi ndi mphotho ya Nobel mu chemistry. Graphene imatha kusakanikirana ndi pulasitiki, kupereka mphamvu ya pulasitiki zodabwitsa kwambiri, ndikupanga pulasitiki yophatikizika kwambiri. Kuphatikiza pa kukonza katundu wakuthupi ndi makina, graphene amawonjezera zotchinga zakumwa ndi mpweya, zimateteza ku nyengo, makutidwe, ndi magetsi a uV, ndikusintha mawonekedwe amagetsi komanso kutentha.
