I-homopolymer ecocekile inzima, i-brittle futhi inzima ukuyicubungula kepha iyaguquguquka uma ifakwe ipulasitiki. Ama-Polyvinyl chloride compounds compounds angakhishwa, umjovo ubunjwe, ukuminyaniswa okubunjiwe, kukhalenda, futhi kushaywe kubunjwe ukwakha izinhlobo eziningi zemikhiqizo eqinile eguquguqukayo. Ngenxa yokusetshenziswa kwayo kabanzi njengamaphayiphi wamanzi angcolile angaphakathi nangaphakathi, izinkulungwane nezinkulungwane zamathani we-PVC zikhiqizwa minyaka yonke.
31) i-PVDF (iKynar®)
Izinhlaka ze-PVDF zisetshenziselwa amandla, amandla avuselelekayo, kanye nezimboni ezisebenza ngamakhemikhali ukumelana kwazo nokushisa, amakhemikhali anamandla nemisebe yenuzi. I-PVDF iyasetshenziswa nasezimbonini zemithi, ezokudla neziphuzo kanye nama-semiconductor ngokuhlanzeka kwayo okuphezulu nokutholakala ngezinhlobo eziningi. Ingasetshenziswa nasezimbonini zezimayini, zokucwebezela nezokulungisa izinsimbi ukumelana kwayo nama-acid ashisayo anezindawo ezahlukahlukene zokugxila. I-PVDF iyasetshenziswa futhi ezimakethe zezimoto nezokwakha ukumelana kwayo namakhemikhali, isimo sezulu esihle kakhulu nokumelana nokonakala kwe-UV.
32) I-Rexolite®
I-Rexolite® ipulasitiki eqinile futhi eguquguqukayo ekhiqizwa yi-cross-linking polystyrene ne-divinylbenzene. Isetshenziselwa ukwenza amalensi ama-microwave, ama-microwave circry, izimpondo, izixhumi zekhebula le-coaxial, ama-transducers womsindo, izitsha ze-satellite ze-satellite nama-sonar lens.
33) iSantoprene®
Ama-Santoprene® thermoplastic vulcanizates (ama-TPVs) angama-elastomers asebenza kahle ahlanganisa izimfanelo ezinhle zenjoloba eyenziwe ngensimbi - njengokuguquguquka kanye nokusethwa kokucindezelwa okuphansi - ngokusebenziseka kalula kwe-thermoplastics. Kuzicelo zabathengi nezomkhiqizo, inhlanganisela yezakhiwo zeSantoprene TPV kanye nokwenza lula ukucubungula kuletha ukusebenza okuthuthukile, ikhwalithi engaguquki nezindleko zokukhiqiza eziphansi. Ekufakeni izicelo zezimoto, isisindo esincane samaSantoprene TPVs sinikela ekwenzeni ngcono ukusebenza kahle, ukonga uphethiloli nezindleko ezincishisiwe. I-Santoprene nayo inikela ngezinzuzo eziningi ezinhlelweni zokusebenza, ezikagesi, ezokwakha, ezokunakekelwa kwempilo kanye nezicelo zokupakisha. Imvamisa futhi isetshenziselwa ukweqisa izinto ezifana namabhulashi wamazinyo, izibambo, njll.
I-34) TPU (Isoplast®)
Yenzelwe ekuqaleni ukusetshenziswa kwezokwelapha, i-TPU iyatholakala kumabanga amade agcwele ingilazi. I-TPU ihlanganisa ukuqina nokuqina kobukhulu bezinhlaka ze-amorphous nokumelana kwamakhemikhali ngezinto zekristallini. Amabanga amade aqinisiwe we-fiber aqinile ngokwanele ukuthi angafaka ezinye izinsimbi kuzicelo zokuthwala umthwalo. I-TPU ibuye ibe nolwandle lwamanzi nolwe-UV, okwenza kube kuhle ekusetshenzisweni kwamanzi.
Amabanga: ama-40% agcwele ingilazi, ama-30% agcwele ingilazi, ama-60% agcwele ingilazi
35) UHMW®
Isisindo se-Ultra High Molecular (UHMW) Polyethylene kuvame ukubizwa ngokuthi yi-polymer enzima kunazo zonke emhlabeni. I-UHMW iyi-polyethylene eqondile, e-ultra high-density enokuqina okukhulu kokuhuzuka kanye namandla amakhulu omthelela. I-UHMW nayo iyamelana namakhemikhali futhi ine-coefficient ephansi yokungqubuzana eyenza iphumelele kakhulu ezinhlelweni ezahlukahlukene. I-UHMW ingaxhunyaniswa, iphinde yenziwe kabusha, ifaniswe ngombala, yenziwe ngomshini futhi yakhiwe ukuze ihlangabezane nezidingo zamakhasimende eziningi. Iyakhishwa kepha ayijojeki ngomjovo. Ukuthambisa kwayo okungokwemvelo kuholela ekusetshenzisweni okubanzi kwama-skid, amagiya, ama-bushings, nezinye izinhlelo zokusebenza lapho kudingeka khona ukushibilika, i-meshing noma ezinye izindlela zokuxhumana, ikakhulukazi embonini yokwenza amaphepha.
36) IVespel®
IVespel yinto ephezulu yokusebenza kwe-polyimide. Ingenye yamaplastiki wobunjiniyela enza kahle kakhulu njengamanje atholakalayo. IVespel ngeke incibilike futhi ingasebenza ngokuqhubekayo kusuka emazingeni okushisa we-cryogenic kuye ku-550 ° F (288 ° C) ngohambo oluya ku-900 ° F (482 ° C). Izinto zeVespel zihlala zibonisa ukusebenza okuphezulu ezinhlotsheni ezahlukahlukene ezidinga ukugqoka okuphansi nempilo ende ezindaweni ezinzima. Ingasetshenziselwa izindandatho zokujikeleza ezijikelezayo, ama-washer we-thrust kanye nama-discs, ama-bushings, ama-blanged bearings, ama-plunger, ama-vacuum pads, kanye nama-insulators ashisayo nagesi. Ukuphazamiseka kwayo okukodwa izindleko zayo eziphakeme kakhulu. Induku engu-¼ ”ububanzi, engama-38” ubude, ingabiza u- $ 400 noma ngaphezulu.
