Polypropylene resin iji mepụta ihe nkiri OPP,
Polypropylene bụ resin sịntetik mere site na polymerization nke propylene (CH3-CH = CH2) na H2 dị ka ihe ngbanwe nke ịdị arọ molekụla.Enwere stereomers atọ nke PP - isotactic, atactic na syndiotactic.PP enweghị otu pola ma nwee ezigbo mkpuchi ọkụ eletrik.Ọnụ nnabata mmiri ya erughị 0.01%.PP bụ polymer semi-crystalline nwere ezigbo nkwụsi ike kemịkalụ.Ọ kwụsiri ike na ọtụtụ kemịkalụ ma ewezuga oxidizers siri ike.Inorganic acid, alkali na nnu ngwọta enweghị ihe fọrọ nke nta ka ọ bụrụ mmetụta na-emebi emebi na PP.PP nwere ezigbo nguzogide okpomọkụ na obere njupụta.Ebe mgbaze ya dị gburugburu 165 ℃.Ọ nwere nnukwu ike ike na elu ike na ezigbo mgbawa mgbawa gburugburu ebe obibi.Ọ nwere ike idi 120 ℃ na-aga n'ihu.
Sinopec bụ onye na-emepụta PP kasị ukwuu na China, ikike PP ya ruru 45% nke ikike obodo.Ụlọ ọrụ ahụ nwere osisi 29 PP ugbu a site na usoro na-aga n'ihu (gụnyere ndị a na-ewu).Teknụzụ ndị nkeji ndị a na-eji gụnyere Mitsui Chemical's HYPOL usoro, usoro gas nke Amoco, Basell's Spheripol na Spherizone usoro na Novolen's gas frasi.Site n'ikike nyocha sayensị siri ike, Sinopec ewepụtala usoro nhazi nke ọgbọ nke abụọ maka mmepụta PP.
