Liketsong tsa likoloi, boima bo bobebe ba li-TPV tsa Santoprene li kenya letsoho ntlafatsong ea ts'ebetso, moruo oa mafura le litšenyehelo tse fokotsoang. Santoprene e boetse e fana ka melemo e mengata ts'ebelisong ea lisebelisoa, motlakase, kaho, tlhokomelo ea bophelo bo botle le liphutheloana. Hangata e sebelisoa ho fetisa lintho tse ngata tse kang borashe ba meno, mehele, jj.
EA-34-TPU (Isoplast®)
E qapiloe qalong bakeng sa ts'ebeliso ea bongaka, TPU e fumaneha ka limaraka tse telele tse tlatsitsoeng ka khalase. TPU kopanya thatafala le tlhakore botsitso ea lehoakhoa amorphous le ho hanyetsa lik'hemik'hale tsa thepa kristale. Limaraka tse matlafalitsoeng tse telele li na le matla a lekaneng ho nka sebaka sa lisebelisoa tse ling lits'ebetsong tse nang le mojaro. TPU e boetse e hanela metsi a leoatle le UV, e leng se etsang hore e be se loketseng litšebeliso tsa ka tlasa metsi.
Mekhahlelo: 40% e tletse khalase, 30% e tletse likhalase tse khutšoane, 60% e tletse likhalase
35) UHMW®
Polyethylene ea High High Molecular (UHMW) hangata e bitsoa polymer e thata ka ho fetesisa lefatšeng. UHMW ke linear, ultra high-density polyethylene e nang le khanyetso e phahameng ea abrasion hammoho le matla a matla a phahameng. UHMW e boetse e hanela lik'hemik'hale ebile e na le coefficient e tlase ea khohlano e etsang hore e sebetse hantle lits'ebetsong tse fapaneng. UHMW e ka hokahanngoa ka sefapano, ea nchafatsoa, ea tsamaellana le 'mala, ea sebelisoa le ho iqapeloa ho fihlela litlhoko tse ngata tsa bareki. E ea putlama empa ha e sebetse ka ente. Lubricity ea lona ea tlhaho e lebisa ts'ebelisong e pharalletseng ea li-skid, likere, li-bushings le lits'ebetso tse ling moo ho hlokahalang ho thellisa, meshing kapa mefuta e meng ea puisano, haholoholo indastering ea ho etsa pampiri.
36) Vespel®
Vespel ke sesebelisoa se sebetsang sa polyimide. Ke e 'ngoe ea li-plastiki tsa boenjiniere tse sebetsang ka ho fetisisa tse fumanehang hajoale. Vespel e ke ke ea qhibiliha mme e ka sebetsa ka ho tsoelang pele ho tloha ho lithemparetjha tsa cryogenic ho isa ho 550 ° F (288 ° C) ka maeto a ho ea 900 ° F (482 ° C). Likarolo tsa Vespel li lula li bonts'a ts'ebetso e phahameng lits'ebetsong tse fapaneng tse hlokang ho roala hanyane le ho phela nako e telele maemong a mabe. E ka sebelisoa bakeng sa masale a tiisang a rotary, li-washer le li-discs, li-bushings, li-bearings tse flanged, li-plunger, liphahlo tsa lephaka, le li-insulator tsa motlakase le tsa motlakase. Bothata ba eona bo le bong ke litšenyehelo tsa eona tse holimo haholo. Thupa ea bophara ba ¼ ”, e bolelele ba 38”, e ka bitsa $ 400 kapa ho feta.
