1、 Mbale ya pulasitiki ya polypropylene, yomwe imadziwikanso kuti mbale ya pulasitiki ya PP, ili ndi mphamvu zambiri komanso kukana dzimbiri, imatha kupirira kutentha kwambiri, ndipo imatha kupirira kukhudzana kwambiri ndi zinthu zina. Imatha kudzazidwa, kulimba, kuletsa moto komanso kusinthidwa. Mbale ya pulasitiki yamtunduwu imakonzedwa pogwiritsa ntchito extrusion, calendering, kuziziritsa, kudula ndi njira zina. Ili ndi ubwino wofanana ndi makulidwe, yosalala komanso yosalala, komanso kutchinjiriza kwamphamvu. Itha kugwiritsidwa ntchito mu zida zotsutsana ndi dzimbiri, mapaipi opumira mpweya, zida zamagetsi ndi zamagetsi, zipangizo zomangira ndi zina, ndipo kutentha kwa ntchito kumatha kufika 100 ℃.

2、 Pepala la pulasitiki la polyethylene limatchedwanso pepala la pulasitiki la PE. Mtundu wa zinthu zopangira umakhala woyera kwambiri. Mtundu wake ukhozanso kusinthidwa malinga ndi zosowa za ogwiritsa ntchito, monga wofiira, wabuluu ndi zina zotero. Uli ndi kukhazikika kwa mankhwala, magwiridwe antchito abwino kwambiri otetezera kutentha, umatha kukana kuwonongeka kwa zinthu zambiri za asidi ndi alkali, kukhuthala kochepa, kulimba bwino, kutambasuka kosavuta, kusunthika mosavuta, si poizoni komanso kopanda vuto. Ntchito zake zikuphatikizapo: mapaipi amadzi, zipangizo zachipatala, mbale zodulira, ma profiles otsetsereka, ndi zina zotero.

3、 Mapanelo apulasitiki a ABS nthawi zambiri amakhala a beige ndi oyera, okhala ndi mphamvu zambiri zogwira ntchito, okana kutentha bwino, okhala ndi mawonekedwe apamwamba komanso osavuta kugwiritsa ntchito. Amagwiritsidwa ntchito kwambiri m'zida zapakhomo, zamagetsi, ma CD, zida zamankhwala ndi zina. Mbale yojambulidwa ya ABS ndi yokongola komanso yopatsa chidwi, makamaka imagwiritsidwa ntchito popanga mapanelo amkati ndi zitseko zamagalimoto. Pepala lotulutsidwa la ABS lili ndi mtundu wokongola, magwiridwe antchito abwino, magwiridwe antchito abwino a thermoplastic komanso mphamvu yogwira ntchito kwambiri. Amagwiritsidwa ntchito kwambiri popanga mabolodi osapsa ndi moto, makoma ndi mabolodi a chassis, ndipo amatha kukonzedwa pogwiritsa ntchito njira zoletsa moto, kuyika, kuyika mchenga ndi njira zina zogwirira ntchito.

4、 Chipepala cha pulasitiki cholimba cha PVC, chomwe chimadziwikanso kuti pepala la pulasitiki lolimba la PVC, chili ndi mitundu yofanana ya imvi ndi yoyera, mankhwala okhazikika, kukana dzimbiri bwino, kukana kwa UV kwambiri komanso kukonzedwa kosavuta. Ntchito yake ndi kuyambira pa minus 15 ℃ mpaka minus 70 ℃. Ndi chinthu chabwino kwambiri chopangira kutentha. Chimatha kusintha chitsulo chosapanga dzimbiri ndi zinthu zina zopangidwa zomwe sizingadzimbidwe ndi dzimbiri. Chagwiritsidwa ntchito m'mafakitale a petrochemical, mankhwala ndi zamagetsi, komanso kulumikizana ndi kutsatsa. Izi ndi chiyambi cha mawonekedwe enieni a mapepala apulasitiki a PVC.
