Mapulasitiki osagwiritsa ntchito malawi amapangidwa kuti azitha kuyatsa, kufalikira kwa moto pang'onopang'ono, komanso kuchepetsa utsi, zomwe zimapangitsa kuti zikhale zofunika kwambiri pakugwiritsa ntchito komwe chitetezo chamoto chimakhala chofunikira. Mapulasitikiwa amaphatikiza zinthu zina monga ma halogenated compounds (monga bromine), phosphorous-based agents, kapena ma inorganic fillers ngati aluminiyamu hydroxide. Zikatenthedwa, zowonjezerazi zimatulutsa mpweya woletsa moto, zimapanga zotchingira zoteteza, kapena zimatenga kutentha kuti zichedwetse kuyaka.
Amagwiritsidwa ntchito kwambiri m'mafakitale amagetsi, zomangamanga, ndi zamagalimoto, mapulasitiki osagwira ntchito ndi malawi amakwaniritsa miyezo yolimba yachitetezo (mwachitsanzo, UL94). Mwachitsanzo, amateteza mpanda wamagetsi kumoto wocheperako ndikuwonjezera kulimba kwa zida zomangira. Komabe, zowonjezera zachikhalidwe za halojeni zimadzetsa nkhawa zachilengedwe chifukwa cha mpweya wapoizoni, zomwe zimapangitsa kuti pakhale kufunikira kwa njira zina zokomera zachilengedwe monga kuphatikiza kwa nayitrogeni-phosphorous kapena mayankho a mineral.
Zatsopano zaposachedwa zimayang'ana pa nanotechnology ndi zowonjezera zochokera ku bio. Nanoclays kapena ma carbon nanotubes amathandizira kukana moto popanda kuwononga makina, pomwe ma lignin opangidwa ndi lignin amapereka zosankha zisathe. Zovuta zimakhalabe pakulinganiza kuchedwa kwa moto ndi kusinthasintha kwazinthu komanso kuwononga ndalama.
Pamene malamulo akumangirira komanso mafakitale amaika patsogolo kukhazikika, tsogolo la mapulasitiki oyaka moto ali muzinthu zopanda poizoni, zomwe zimagwira ntchito kwambiri zomwe zimagwirizana ndi mfundo zachuma zozungulira. Kupititsa patsogolo kumeneku kumapangitsa kuti zinthu zikhale zotetezeka komanso zobiriwira pakugwiritsa ntchito masiku ano.
