• Iguquguquka emazingeni okushisa aphansi (-40°C kuya ku-+120°C).

• Izinzuzo:

• Ibiza kakhulu ngokucubungula okulula (i-extrusion/molding).

• Amandla aphezulu emishini kanye nokumelana nemihuzuko.

• Izicelo:

• Amasudi amanzi, amagilavu, namapayipi asebenza ezimbonini.

• Izinamathiselo zezicathulo nokwakhiwa.

• Amajakhethi ekhebula nolwelwesi lwamafulelo.

3. Irabha ye-Nitrile ene-Hydrogenated (HNBR)

• Izakhiwo:

• Ukumelana nokushisa okuthuthukisiwe (kufika ku-+150°C) uma kuqhathaniswa ne-NBR.

• Ukumelana okuphezulu nowoyela, uketshezi olunamanzi, nama-amine.

• Amandla aqinile aphezulu kanye nokumelana nokukhathala.

• Ukungena kancane kumagesi.

• Izinzuzo:

• Igcina ukunwebeka ngaphansi kokuchayeka isikhathi eside kumakhemikhali anonya.

• Impilo ende kune-NBR ezimeni ezimbi kakhulu.

• Izicelo:

• Amathuluzi okumba uwoyela negesi (amapaki, ama-seal).

• Amabhande esikhathi sezimoto, izingxenye zomjovo kaphethiloli, nezigxivizo ze-turbocharger.

• Amasilinda e-hydraulic hydraulic.

4. Irabha ye-Silicone (VMQ)

• Izakhiwo:

• Ibanga lokushisa elibanzi kakhulu (-60°C ukuya +200°C).

• Ukunwebeka okuphezulu (kufika ku-1000% elongation).

• Ukufakwa kukagesi okuhle kakhulu nokuzinza kokushisa.

• I-Biocompatible futhi inert.

• Izinzuzo:

• Igcina ukuguquguquka kwemvelo endaweni ye-cryogenic kanye ne-high-temperature.

• Imelana ne-UV, i-ozone, nesimo sezulu.

• Izicelo:

• Imishini yezokwelapha (ama-catheters, izimila).

• Izingxenye ze-elekthronikhi (ama-insulators, amakhiphedi).

• Ama-gaskets anezinga lokushisa eliphezulu lamahhavini nezinjini.

5. Irabha ye-Fluorosilicone (FVMQ)

• Izakhiwo:

• Ihlanganisa ukumelana kwamakhemikhali kwe-FKM kanye nokuguquguquka kwe-VMQ.

• Ibanga lokushisa: -50°C ukuya +230°C.

• Ingazweli kumafutha, okothambisa, noketshezi olusebenzisa amanzi.

• Isethi yokucindezela ephansi kanye nokuqina okuhle.

• Izinzuzo:

• Isebenza kuwo womabili amazinga okushisa aphezulu kanye namazinga okushisa aphansi.

• Imelana nokuvuvukala kwezibaseli zezindiza.

• Izicelo:

• Izingxenye zesistimu yamafutha endiza (ama-valve, ama-seal).

• Ama-gaskets angaphansi kwamanzi olwandle kanye nezixhumi.

• Izinzwa zezimoto nezinhlelo zokulawula ukungcola.

6. I-Ethylene Propylene Diene Monomer (EPDM)

• Izakhiwo:

• I-ozone evelele kanye nokumelana nesimo sezulu.

• Amandla aphezulu e-dielectric kanye nokumelana namanzi.

• Ibanga lokushisa: -50°C kuya +150°C.

• Ukungena kwegesi okuphansi.

• Izinzuzo:

• Ibiza kakhulu izinhlelo zokusebenza zangaphandle.

• Ukudambisa ukudlidliza okuhle kakhulu nokunciphisa umsindo.

• Izicelo:

• I-Weatherstripping yezimoto, amapayipi erediyetha, nama-windshield seal.

• Ama-membrane ophahla kanye nama-pond liners.

• Ukufakwa kwezintambo zikagesi namambonini ezihlukahlukene lapho izinga lokushisa elidlulele kanye nezindawo ezinokhahlo kuyisenzakalo esivamile. Lawa mapayipi aklanyelwe ukumelana nezinga lokushisa eliphezulu, okuwenza alungele ukusetshenziswa okubandakanya ukuthuthwa koketshezi olushisayo noma amagesi.
