Graphene imawonjezera mphamvu za pulasitiki pamene imachepetsa kugwiritsa ntchito zinthu zopangira ndi 30 peresenti.

Gerdau Graphene, kampani ya nanotechnology yomwe imapereka zipangizo zamakono zogwiritsidwa ntchito m'mafakitale, yalengeza kuti yapanga mapulasitiki atsopano opangidwa ndi graphene kuti agwiritsidwe ntchito m'mafakitale ku Center for Advanced Materials yomwe imathandizidwa ndi boma la Brazil ku São Paulo, Brazil. Fomula yatsopano ya graphene-enhanced polymeric resin masterbatch formulation ya propylene (PP) ndi polyethylene (PE) idapangidwa mogwirizana ndi gawo la Brazilian EMBRAPI SENAI/SP Advanced Materials, ndipo pakadali pano ikuyesedwa kangapo pakugwiritsa ntchito mafakitale ku Gerdau Graphene facility. Zinthu zatsopano za thermoplastic zopangidwa pogwiritsa ntchito njirazi zidzakhala zolimba komanso zimapereka magwiridwe antchito abwino pomwe zimakhala zotsika mtengo kupanga ndikupanga zinyalala zochepa kwambiri mu unyolo wonse wamtengo wapatali.
Graphene, yomwe imaonedwa kuti ndi chinthu champhamvu kwambiri padziko lapansi, ndi pepala lolimba la kaboni lokhala ndi maatomu 1 mpaka 10 okhuthala lomwe lingasinthidwe kuti ligwiritsidwe ntchito mosiyanasiyana ndikuwonjezeredwa kuzinthu zamafakitale. Kuyambira pomwe idapezeka mu 2004, mphamvu zodabwitsa za graphene zamakemikolo, zakuthupi, zamagetsi, kutentha ndi zamakanika zakopa chidwi padziko lonse lapansi, ndipo wopezayo wapatsidwa Mphoto ya Nobel mu Chemistry. Graphene ikhoza kusakanikirana ndi mapulasitiki, kupatsa pulasitiki ya masterbatch mphamvu yodabwitsa, kupangitsa pulasitiki yophatikizidwa kukhala yolimba kwambiri. Kuphatikiza pa kukonza mphamvu zakuthupi ndi zamakanika, graphene imakulitsa mphamvu zotchinga zakumwa ndi mpweya, imateteza ku nyengo, kukhuthala, ndi kuwala kwa UV, komanso imawongolera kuyendetsa magetsi ndi kutentha.
