(1) Ngwongwo anụ ahụ: PP ákwà na-adịghị kpara akpa bụ ihe na-adịghị egbu egbu, mmiri ara ehi na-enweghị ụtọ na-acha ọcha elu kristal polymer, nke bụ otu n'ime ụdị ọkụ dị iche iche nke plastik ugbu a.Ọ na-akwụsi ike na mmiri, yana ọnụego mmịnye mmiri na mmiri bụ naanị 0.01% mgbe awa 14 gachara.The molekụla arọ bụ banyere 80,000 ~ 150,000, na ezi formability.Otú ọ dị, n'ihi nnukwu nkwụsịtụ, ngwaahịa mgbidi mbụ ahụ dị mfe ịkwaga, na elu nke ngwaahịa na-egbuke egbuke ma dị mfe agba.
(2) Mechanical Njirimara: PP na-abụghị kpara akwa nwere elu crystallinity na mgbe Ọdịdị, ya mere o nwere magburu onwe n'ibu Njirimara.Ike ya, ike ya na ngbanwe dị elu karịa nke PE dị elu (HDPE).Akụkụ pụtara ìhè bụ ịgbagọ nkwụsi ike ike ọgwụgwụ (7 × 10 ^ 7) A na-ehulata oghere na mmechi nke abụọ na-enweghị mmebi, yana ọnụọgụ esemokwu akọrọ yiri naịlọn, mana ọ dị ala karịa naịlọn n'okpuru mmanu mmanụ.
(3) Thermal arụmọrụ: PP na-abụghị kpara ákwà nwere ezigbo okpomọkụ na-eguzogide, agbaze ebe bụ 164 ~ 170 ℃, na ngwaahịa nwere ike igba ogwu na okpomọkụ n'elu 100 ℃.N'okpuru omume nke enweghị mpụga ike, ọ gaghị deform na 150 ℃.The embrittlement okpomọkụ bụ - 35 ℃, nke ga-eme n'okpuru - 35 ℃, na okpomọkụ na-eguzogide adịghị mma dị ka PE.
(4) Nkwụsi ike nke kemịkalụ: PP anaghị kpara akwa nwere ezigbo nkwụsi ike kemịkalụ.Na mgbakwunye na acid na-emebi emebi, ọ kwụsiri ike na reagents ndị ọzọ.Otú ọ dị, obere molecular arọ aliphatic hydrocarbons, aromatic hydrocarbons, wdg nwere ike nro na zaa PP na-abụghị kpara ákwà, na kemịkalụ kwụsie ike na-mma na-abawanye nke crystallinity.Ya mere, PP na-adịghị akwa ákwà kwesịrị ekwesị maka ịmepụta ọkpọkọ kemịkalụ Russia na Chinese na ngwa ngwa, na-enwe mmetụta mgbochi corrosion dị mma.
(5) Ọrụ eletriki: Ọrụ mkpuchi mkpuchi ugboro ugboro nke akwa na-abụghị akwa dị mma.N'ihi na ọ fọrọ nke nta ka ọ ghara ịmịnye mmiri, ọrụ mkpuchi adịghị emetụta iru mmiri.Ọ nwere ọnụọgụ dielectric dị elu.Site na mmụba nke okpomọkụ, enwere ike iji ya mee ngwaahịa mkpuchi ọkụ eletrik.Voltaji mmebi ahụ dịkwa oke elu, ọ dịkwa mma maka ngwa eletriki.Ezigbo nguzogide voltaji na nguzogide arc, mana ọkụ eletrik dị elu, dị mfe ịka nká mgbe ị na-akpọtụrụ ọla kọpa.
(6) Nguzogide ihu igwe: akwa ndị na-abụghị akwa na-enwe mmetụta nke ukwuu na ìhè ultraviolet, a pụkwara imeziwanye nguzogide ịka nká site n'ịgbakwunye zinc oxide thiopropionic acid lauryl ester, carbon black dị ka milky white filler, wdg.
