Iintlobo zeepolypropylene .

Iimolekyuli zePolypropylene ziqulathe amaqela e-methyl, anokwahlulwa abe yi-isotactic polypropylene, atactic polypropylene kunye ne-sydiotactic polypropylene ngokwelungiselelo lamaqela e-methyl. Xa amaqela e-methyl ehlelwe kwicala elinye lekhonkco eliphambili, libizwa ngokuba yi-isotactic polypropylene; ukuba amaqela e-methyl asasazwa ngokungenamkhethe kumacala omabini ekhonkco eliphambili, libizwa ngokuba yi-atactic polypropylene; xa amaqela e-methyl ecwangciswe ngokutshintshanayo kumacala omabini ekhonkco eliphambili, libizwa ngokuba yi-sydiotactic. polypropylene. Kwimveliso jikelele ye-polypropylene resin, umxholo wesakhiwo se-isotactic (ebizwa ngokuba yi-isotacticity) malunga ne-95%, kwaye enye i-atactic okanye i-sydiotactic polypropylene. I-resin ye-polypropylene eveliswa ngoku e-China ihlelwa ngokwe-melt index kunye ne-additives eyongeziweyo.

I-Atactic polypropylene yimveliso yemveliso ye-isotactic polypropylene. I-Atactic polypropylene iveliswa kwimveliso ye-isotactic polypropylene, kunye ne-isotactic polypropylene ihlukaniswe kwi-polypropylene ye-atactic ngendlela yokwahlukana.

I-Atactic polypropylene yimathiriyeli enwebekayo kakhulu ye-thermoplastic enamandla okuqina. Inokuthi ifakwe i-vulcanized njengerabha ye-ethylene-propylene.
