Polypropylene (PP): Polypropylene ndi thermoplastic yopangidwa ndi theka-crystalline, yokhala ndi mphamvu zambiri komanso yolimba, komanso yosavuta kuikonza. Ma casters a PP nthawi zambiri amakhala olimba komanso amphamvu, oyenera nthawi zina zomwe zimafuna mphamvu zambiri.
Rabala ya Thermoplastic (TPR): Rabala ya Thermoplastic ndi mtundu wa thermoplastic wokhala ndi kusinthasintha kwa rabala, kusinthasintha bwino komanso kukana kuwonongeka, ma casters a TPR nthawi zambiri amakhala ndi kapangidwe kofewa, koyenera nthawi zomwe zimafuna kutetezedwa komanso chete.

Chachiwiri, makhalidwe a ntchito
Kukana Kutupa: Kukana kutupa kwa ma casters a TPR ndikwabwino kuposa kwa ma casters a PP chifukwa ali ndi malo ofewa omwe amatha kusinthasintha bwino pansi.
Kukana kugwedezeka: Ngakhale kuti ma casters a PP ali ndi kukana kugwedezeka bwino, nthawi zina, ma casters a TPR angakhale ndi kukana kugwedezeka kwambiri.
Kukonza: Ma casters a PP ndi osavuta kuwakonza ndipo amatha kuumbidwa ndi jakisoni kutentha kwambiri. Ma casters a TPR ndi osavuta kuwakonza ndipo nthawi zambiri amafunika kugwiritsa ntchito jakisoni wachiwiri.
Mtengo: Kawirikawiri, ma casters a TPR ndi okwera mtengo kuposa ma casters a PP chifukwa cha njira yovuta yopangira.

Kugwiritsa ntchito
Ma casters a PP: oyenera nthawi zomwe zimafuna mphamvu zambiri zonyamulira katundu komanso kukana kuwonongeka kwambiri, monga zida zolemera, mashelufu, ndi zina zotero.
Zipangizo zoyezera za TPR: zoyenera kusinthasintha bwino, kukana kugunda bwino, kukana kuvala, monga zida zachipatala, zida za labotale.
