Gawo la pulasitiki ndi gawo la mauna lomwe limapangidwa pokonza ndikuphatikiza matabwa apulasitiki opanda kanthu.
Zogwiritsidwa ntchito muzakudya, zinthu zaulimi, mabokosi oyika zida za Hardware, zitha kugwiritsidwanso ntchito nthawi zambiri. The olekanitsa mu ma CD mankhwala angalepheretse extrusion ndi kugunda kwa zinthu, ndipo amagwiritsidwanso ntchito monga zopangira kwa mkati ma CD olekanitsa pulasitiki zida mwatsatanetsatane. Bolodi lopanda kanthu la pulasitiki limapangidwa makamaka ndi polyethylene yolimba kwambiri komanso polypropylene. Pepala la pulasitiki lopanda kanthu lopangidwa ndi compression molding. Ili ndi mawonekedwe osakhala ndi poizoni, osanunkhira, osagwirizana ndi chinyezi, osachita dzimbiri, opepuka, owoneka bwino, olemera komanso oyera, mphamvu zonyamula, ndi zina zambiri.
Zopanda fungo komanso zopanda poizoni. Chifukwa cha kapangidwe kake komanso kukhathamiritsa kwakukulu, malo osungunuka amatha kufika 167 ° C. Kutentha kwa kutentha ndi kukana kwa dzimbiri, ndipo zinthuzo zimatha kutsukidwa ndi nthunzi ndizo zabwino zake. Ndi kachulukidwe kakang'ono, ndiye pulasitiki yopepuka kwambiri yogwiritsidwa ntchito nthawi zonse. Choyipa chake ndikuti chimakhala ndi kukana kwamphamvu kwa kutentha kochepa komanso kosavuta kukalamba, koma kumatha kugonjetsedwa ndikusintha. Zida za PP zamtundu wa copolymer zimakhala ndi kutentha kwapang'onopang'ono (100 ° C), kuwonekera pang'ono, gloss pang'ono, komanso kusasunthika pang'ono, koma zimakhala ndi mphamvu zokulirapo. Mphamvu yamphamvu ya PP imawonjezeka ndi kuchuluka kwa ethylene. . Kutentha kwa Vicat kufewetsa kwa PP ndi 150 ° C. Chifukwa cha kuchuluka kwa crystallinity, nkhaniyi imakhala ndi kuuma kwapamwamba komanso kukana kukana. PP ilibe zovuta zosokoneza chilengedwe.
