I-Edge Rubber Grommet, ebizwa ngokuba yi-edge rubber sheath, luhlobo lwemveliso yerabha esetyenziselwa ukukhusela umda kwiimpembelelo zangaphandle. Isetyenziswa ikakhulu ukwahlula edge izinto, uzikhusele kulwelo ezahlukeneyo, uthuli, ukungcola, njalo njalo, kwaye kwangaxeshanye, nako nokukhusela izinto umonakalo ngokwasemzimbeni, ukukhuhlana, ukungcangcazela, njl Umzekelo, kumashishini ezifana iimoto, izixhobo zombane, kunye nefanitshala, ingasetyenziselwa ukukhusela iingcingo, iintambo okanye iintambo okanye imibhobho yokuthintela ukunqunyulwa kwentsimbi okanye imibhobho yokuthintela ukusika okanye iipayipi zentsimbi okanye i-wornles. njengeesekethe ezimfutshane kunye nokusilela kwezixhobo ezibangelwa ngumonakalo wentambo.

Iimpawu zeRubber ye-NBR:
Irabha yeNitrile (NBR, Buna{0}}N) inika ukuxhathisa okugqwesileyo kwi-oyile ye-petroleum kunye neminerali kunye ne-oyile yemifuno. Irabha yeNitrile ikwabonelela ngamandla okumelana nobushushu ukuguga - isoloko iluncedo oluphambili kwirabha yendalo.
Irabha ye-nitrile isebenza kakuhle kwi-carburetor kunye ne-diaphragm yempompo yamafutha, imibhobho yenqwelo-moya, itywina kunye neegaskithi kunye ne-oyile{0}}efakwe iityhubhu. Ngenxa yokuguquguquka kwayo, i-nitrile isetyenziswa kwizicelo ezibandakanya ukunganyangeki kwe-oyile kunye ne-petroli kuphela, kodwa ezo zicelo zifuna ukuxhathisa ubushushu, i-abrasion, amanzi, kunye nokungena kwegesi.

Iimpawu zeRubber ye-FKM:
Vi-itoni yeyeqela leFluoroelastomers (FKM/FPM) leekhompawundi zerabha. Kukho amabakala amaninzi kunye nobunzima bokusombulula uninzi lwezicelo kunye neendlela ezahlukeneyo zokuhlangabezana neemfuno ezithile zobushushu kunye nokumelana neekhemikhali. Usetyenziso oluqhelekileyo lubandakanya: ukuxhathisa ubushushu okugqwesileyo, iipropathi ezilungileyo zoomatshini, ukunyanzeliswa okuhle kweseti yokumelana, ukumelana noluhlu olubanzi lweeoyile kunye namafutha, ukuxhathisa izinyibilikisi; ngakumbi zonke i-aliphatic, i-aromatics kunye ne-halogenated hydrocarbons kunye ne-asidi.

Iimpawu zeRubber ye-EPDM:
Irabha ye-EPDM yirabha yoxinaniso oluphezulu olusetyenziswa ikakhulu kwizicelo zangaphandle. Ineempawu eziguquguqukayo kunye nezomatshini phakathi kwerabha yendalo kunye nerabha yokwenziwa.
Musa ukusebenzisa i-EPDM ukuba uqhagamshelwano oluqhubekayo kunye neemveliso ezisekelwe kwipetroleum ziyafuneka.
Ayikhuthazwa ukuba isetyenziswe ekutyeni okanye kwezo zisesichengeni seehydrocarbons ezinevumba elimnandi.

Iimpawu zeRubber yeHNBR:
I-Hydrogenated Nitrile Butadiene Rubber (HNBR), eyaziwa ngokuba yi-Highly SaturatedNitrile (HSN), iklasi ekhethekileyo yerabha ye-nitrile (NBR) eye yafakwa i-hydrogenated ukuze inyuse i-saturation yecandelo le-butadiene ye-carbon polymer backbone. Uphuculo olulandelayo kwiipropati eziphathekayo, ngaphezu kwerabha ye-nitrile (NBR), ibandakanya ukuzinza okukhulu kwe-thermal, ukuchasana kweekhemikhali ngokubanzi, kunye namandla amakhulu okuqina.
I-HNBR ihlelwa yi-ASTM njenge-DH-yohlobo lwepolima. Olu luhlu lubonisa ubushushu benkonzo ye-150ºC kunye nokudumba okungaphantsi kwe-30% kwi-oyile ye-IRM 903. I-HNBR inokuqulunqwa ukuhlangabezana namaqondo obushushu aphakathi kwe -50 kunye ne-165ºC.

Iimpawu zeRubber ye-SBR:
1.Imathiriyeli engundoqo: Irabha ye-Styrene -butadiene (SBR), injongo ngokubanzi{2}}irabha eyenziweyo, eveliswe kwi-copolymer ye-styrene kunye ne-butadiene. Ukodlula zonke ezinye iirubha ezenziweyo ezisetyenziswayo, i-SBR isetyenziswa kakhulu kwimoto kunye namatayara elori, njengesiqhelo njenge-abrasion{4}}ekwaziyo ukubuyisela irabha yendalo (eveliswe kwi-polyisoprene).
2.Indawo efumanekayo: Zisetyenziswa kakhulu kwimoto, izixhobo zombane, ukwahlulwa kwesakhiwo sokungcangcazela kunye nolunye ushishino. Umzekelo, i-air blower, impompo yamanzi, isixhobo, ukulinganisa iinqanawa kunye nokunye.
3.Intsebenzo engundoqo: I-SBR ineepropathi ezifanayo zeekhemikhali kunye nezomzimba kwirabha yendalo, ngokuxhathisa okungcono kwe-abrasion, amandla abalaseleyo, ukunyathela okulungileyo kunye nokumelana noxinzelelo kunye neendleko eziphantsi, njl. Akukhuthazwa ukusebenzisa i-SBR kwizicelo ezibandakanya i-ozone, i-acids eqinile, i-oyile, i-greases, amafutha kunye ne-hydrocarbons ezininzi.

Iimpawu zeRubber yeNeoprene:
Irabha yeNeoprene, ekwabizwa ngokuba yi-neoprene polychloroprene, yirabha eyenziwe ngeendlela ezininzi engaphezulu kweminyaka engama-75 yokusebenza okuqinisekisiweyo.
Kwilizwe leemoto, i-neoprene isetyenziswa kwizinto ezininzi ezingaphantsi-ze{1}}zehood kunye namalungu angaphantsi afuna ixabiso elivakalayo, eliphakathi{2}}lokusebenza kwepolima enezinto ezilungileyo{3}}ezingqonge ibhalansi yezinto zokusebenza.

Iimpawu zeNdalo zerabha:
Irabha yendalo ekuqaleni yayithatyathwe kwi-latex efunyenwe kwincindi yemithi yerabha. Ifomu ecocekileyo yerabha yendalo nayo inokuveliswa ngokwenziwa. Irabha yendalo yipolymer efanelekileyo kwizicelo zobunjineli obuguqukayo okanye obumileyo.
Isilumkiso: I-rubber yendalo ayikhuthazwa kwizicelo apho inxalenye yerabha iya kuboniswa kwi-ozone, i-oyile, okanye i-solvents.

Iimpawu zeRubha zePU/Polyurethane:
I-polyurethane yipolymer ephilayo. I-polyurethanes yenziwe ngokuphendula i-polyol (utywala obunamaqela angaphezu kwamabini asebenzayo e-hydroxyl nge-molecule) kunye ne-disocyanate okanye i-polymeric isocyanate phambi kwee-catalysts ezifanelekileyo kunye nezongezo. I-Polyurethane yikhompawundi esetyenziswa ngokubanzi ngenxa yamandla ayo aphezulu, ukukrazula kunye nokuxhathisa kwe-abrasion. I-Polyurethane ikwabonelela ngokugqwesileyo kokumelana ne-permeation.
