• Kulimba kwamphamvu kwambiri, kutsika kwapang'onopang'ono, komanso kukhazikika kwamphamvu kwamankhwala.

• Kukana moto ndi ozoni.

• Ubwino:

• Imalimbana ndi mankhwala aukali komanso malo opanikizika kwambiri.

• Moyo wautali wautumiki muzamlengalenga ndi ntchito zamagalimoto.

• Mapulogalamu:

• Zosindikizira zamafuta a ndege, ma O-mphete, ndi ma gaskets.

• Zisindikizo zotumizira magalimoto, ma hose a injini, ndi zida za turbocharger.

• Chemical processing zida linings ndi gaskets.

2. Mpira wa Chloroprene (CR)

• Katundu:

• Kukana kwamafuta pang'ono (kuposa mphira wachilengedwe koma kuchepera FKM).

• Cholepheretsa moto chokhala ndi zinthu zozimitsa zokha.

• Kukana kwanyengo (UV, ozoni, ndi chinyezi).

• Kusinthasintha pa kutentha kochepa (-40 ° C mpaka + 120 ° C).

• Ubwino:

• Zotsika mtengo ndi kukonza kosavuta (extrusion/kuumba).

• Mkulu makina mphamvu ndi abrasion kukana.

• Mapulogalamu:

• Zovala zonyowa, magolovesi, ndi ma hoses a mafakitale.

• Zomatira za nsapato ndi zomangamanga.

• Ma jekete achingwe ndi nembanemba zadenga.

3. Mpira wa Nitrile wa Hydrogenated (HNBR)

• Katundu:

• Kutentha kwamphamvu (mpaka +150 ° C) poyerekeza ndi NBR.

• Kukana kwakukulu kwa mafuta, madzimadzi amadzimadzi, ndi amines.

• Kulimba kwamphamvu kwambiri komanso kukana kutopa.

• Low permeability kwa mpweya.

• Ubwino:

• Imasunga elasticity pansi pa kukhudzidwa kwanthawi yayitali ndi mankhwala owopsa.

• Kutalika kwa moyo kuposa NBR m'malo ovuta kwambiri.

• Mapulogalamu:

• Mafuta ndi gasi pobowola zida (packers, zisindikizo).

• Malamba oyendera nthawi yamagalimoto, zida za jakisoni wamafuta, ndi zisindikizo za turbocharger.

• Industrial hydraulic cylinders.

4. Mpira wa Silicone (VMQ)

• Katundu:

• Kutentha kwakukulu kwambiri (-60 ° C mpaka +200 ° C).

• Kuthamanga kwakukulu (mpaka 1000% elongation).

• Kusungunula kwabwino kwamagetsi komanso kukhazikika kwamafuta.

• Biocompatible ndi inert.

• Ubwino:

• Amasunga kusinthasintha m'malo okhala ndi cryogenic komanso kutentha kwambiri.

• Kulimbana ndi UV, ozoni, ndi nyengo.

• Mapulogalamu:

• Zida zamankhwala (catheters, implants).

• Zida zamagetsi (ma insulators, keypad).

• Ma gaskets otentha kwambiri a uvuni ndi injini.

5. Fluorosilicone Rubber (FVMQ)

• Katundu:

• Zimaphatikiza kukana kwa mankhwala a FKM ndi kusinthasintha kwa VMQ.

• Kutentha kwapakati: -50°C mpaka +230°C.

• Kusamva mafuta, mafuta, ndi madzimadzi amadzimadzi.

• Kupanikizika kochepa komanso kupirira bwino.

• Ubwino:

• Zimagwira pa kutentha kwambiri komanso kutentha kwambiri.

• Kulimbana ndi kutupa kwamafuta oyendetsa ndege.

• Mapulogalamu:

• Zida zamafuta a ndege (mavavu, zisindikizo).

• Ma gaskets ozama m'nyanja ndi zolumikizira.

• Masensa agalimoto ndi machitidwe owongolera utsi.

6. Ethylene Propylene Diene Monomer (EPDM)

• Katundu:

• Ozone yabwino kwambiri komanso kukana kwanyengo.

• Mphamvu yapamwamba ya dielectric ndi kukana madzi.

• Kutentha kwapakati: -50°C mpaka +150°C.

• Low mpweya permeability.

• Ubwino:

• Zotsika mtengo kwambiri pazogwiritsa ntchito panja.

• Kugwedera kwabwino kwambiri komanso kuchepetsa phokoso.

• Mapulogalamu:

• Kuwongolera nyengo yamagalimoto, mapaipi a radiator, ndi zisindikizo zapatsogolo.

• Zipinda zapadenga ndi dziwe lamadzi.

• Kutsekereza chingwe chamagetsi ndi malamba otumizira mphamvu.
