1. Rerekē rauemi

Pueke PPhe kapia polypropylene.Na te mea he tino pakarukaru te homopolymer PP ina he teitei ake te pāmahana i te 0C, he maha nga rauemi PP arumoni he copolymers matapōkere me te 1~4% te ethylene kua taapirihia, he rawhi ranei he nui ake te ihirangi ethylene.copolymer tātai.

Ko te PC kei roto i te kete PC he "polycarbonate".Ko te Polycarbonate he kapia wera wera ka mau tona ingoa mai i nga roopu CO3 kei roto.Na te bisphenol A me te waro oxychloride synthesis.Ko te tikanga e whakamahia nuitia ana ko te tikanga whakawhiti rewa (ka whakahiatotia te bisphenol A me te diphenyl carbonate e te transesterification me te polycondensation).

2. Nga ahuatanga rereke

Pueke PP: He iti ake te pāmahana whakakorikori waiariki (100C), he iti te maramatanga, he kanapa iti, he iti te rigidity, engari he kaha ake te kaha o te paanga.Ka piki ake te kaha o te PP me te whakanui ake i te ihirangi ethylene.Ko te pāmahana whakamarumaru Vicat o PP he 150C.Na te nui o te kirikiriata, he pai te pakari o te mata o tenei rauemi me nga taonga atete.

Pueke PC: He kapia thermoplastic amorphous me nga ahuatanga matawhānui tino pai, he pai te whakamaarama hiko, te whakaroa, te pumau o te taha me te aukati matū, te kaha nui, te wera me te makariri;kei a ia ano te tinei-whaiaro, te mura ahi, te kore-paitini, te tae, me era atu.

3. Te kaha rereke

Pueke PP: kia kaha ake te kaha o te paanga.He pai rawa atu te pakari o te mata me te karawarawa o tenei rawa.

Pueke PC: Ka taea e tona kaha te whakatutuki i nga momo hiahia mai i nga waea pūkoro ki te karaehe matā.Ka whakatauritea ki te konganuku, he iti rawa tona pakeke, na te mea ka ngawari ake tona ahua ki te rakuraku, engari he tino pai tona kaha me tona uaua, ahakoa he pehanga taumaha, he whanui ranei, mena kaore koe e ngana ki te toka, he roa rawa.
