Ibikoresho bya polypropylene ikoreshwa mu gushushanya indorerwamo ni ibikoresho bya pulasitiki byahinduwe. Polypropylene ikoreshwa mu gushushanya indorerwamo ikoreshwa mu gushushanya indorerwamo muri rusange ni inkingi y'uduce dufite uburebure bwa mm 12 cyangwa mm 25 n'umurambararo wa mm 3. Muri utu duce, fiberglass ifite uburebure bumwe n'uduce, ingano y'uduce tw'ikirahure ishobora gutandukana kuva kuri 20% kugeza kuri 70% kandi ibara ry'uduce rishobora guhuzwa n'ibyo umukiriya akeneye. Uduce muri rusange dukoreshwa mu gutera no gushushanya kugira ngo hakorwe ibice by'imiterere cyangwa ibice by'imiterere bikoreshwa mu modoka, ubwubatsi, ibikoresho byo mu rugo, ibikoresho by'amashanyarazi n'ibindi byinshi.
Ikoreshwa mu nganda z'imodoka: Amafuremu yo ku ruhande rw'imbere, modules z'umuryango w'umubiri, skeletons za dashboard, fans zo gukonjesha n'amafuremu, amasahani ya bateri, n'ibindi, nk'ibisimbura ibikoresho bya pa cyangwa ibyuma bikonjeshwa.
