• Ngwa:

• Usoro mmanụ ụgbọ elu, O-mgbanaka, na gaskets.

• Akara nnyefe ụgbọ ala, hoses engine, na akụrụngwa turbocharger.

• Kemịkalụ nhazi akụrụngwa lining na gaskets.

2. Chloroprene roba (CR)

• Njirimara:

• Nguzogide mmanụ na-agafeghị oke (dị mma karịa rọba eke mana ọ na-erughị FKM).

• Ọkụ na-egbochi ọkụ nwere ihe na-emenyụ onwe ya.

• Ezigbo nguzogide ihu igwe (UV, ozone, na mmiri).

• Na-agbanwe agbanwe na obere okpomọkụ (-40°C ruo +120°C).

• Uru:

• Ọnụ-irè na mfe nhazi (extrusion / ịkpụzi).

• Ike igwe dị elu na mgbochi abrasion.

• Ngwa:

• Suut mmiri mmiri, uwe aka, na ụdọ ụlọ ọrụ mmepụta ihe.

• Adhesives maka akpụkpọ ụkwụ na ihe owuwu.

• Jaketị eriri na mkpuchi elu ụlọ.

3. Rba Nitrile Hydrogenated (HNBR)

• Njirimara:

• Enwetara nguzogide okpomọkụ (ruo +150 Celsius) ma e jiri ya tụnyere NBR.

• Iguzogide mmanu mmanu, mmiri mmiri hydraulic, na amines.

• Ike ike dị elu na ike ọgwụgwụ.

• Obere permeability na gas.

• Uru:

• Na-ejigide elasticity n'okpuru mkpughe ogologo oge na kemịkalụ siri ike.

• Ogologo ndụ dị ogologo karịa NBR n'ọnọdụ dị oke egwu.

• Ngwa:

• Ngwá ọrụ na-egwupụta mmanụ na gas (packers, seals).

• Akara oge ụgbọ ala, ihe ntụtụ mmanụ ọkụ, na akara turbocharger.

• Ụlọ ọrụ hydraulic cylinders.

4. rọba silicone (VMQ)

• Njirimara:

• Okpomọkụ dị obosara (-60°C ruo +200°C).

• Ọkpụkpụ dị elu (ruo 1000% elongation).

• Ezigbo mkpuchi eletrik na nkwụsi ike thermal.

• Biocompatible na inert.

• Uru:

• Na-ejigide mgbanwe na gburugburu cryogenic na oke okpomọkụ.

• Na-eguzogide UV, ozone, na ihu igwe.

• Ngwa:

• Ngwa ahụike (catheters, implants).

• Ngwa eletrọnịkị (insulators, igodo).

• gaskets okpomọkụ dị elu maka oven na injin.

5. Fluorosilicon roba (FVMQ)

• Njirimara:

• Na-agwakọta mgbochi kemịkalụ FKM na mgbanwe VMQ.

• Okpomọkụ dị nso: -50°C ruo +230°C.

• Na-eguzogide mmanụ ọkụ, lubricants, na mmiri mmiri hydraulic.

• Ntọala mkpakọ dị ala na nkwụsi ike dị mma.

• Uru:

• Na-eme ma na oke okpomọkụ na obere okpomọkụ.

• Na-eguzogide ọzịza na mmanụ ụgbọ elu.

• Ngwa:

• Ihe mejupụtara sistemu mmanụ ụgbọ elu (valvụ, akara).

• gaskets na njikọ njikọ dị n'oké osimiri submersible.

• Ihe mmetụta ụgbọ ala na sistemụ njikwa ikuku.

6. Ethylene Propylene Diene Monomer (EPDM)

• Njirimara:

• Ozone pụtara ìhè na nguzogide ihu igwe.

• Ike dielectric dị elu na nguzogide mmiri.

• Okpomọkụ dị nso: -50°C ruo +150°C.

• Obere gas permeability.

• Uru:

• Kacha dị ọnụ ahịa maka ngwa n'èzí.

• Mmanya ịma jijiji na mbelata mkpọtụ.

• Ngwa:

• Mkpuchi ihu igwe ụgbọ ala, hoses radiator, na mkpuchi ikuku.

• Ihe mkpuchi mkpuchi ụlọ na ọdọ mmiri.

• Igwe mkpuchi ọkụ eletrik na eriri nnyefe ike.
