4. Ngwakọta EPDM (Ethylene Propylene Diene Monomer)

Njirimara:

• Ozone/ ihu igwe pụtara ìhè (awa 5,000+ na ule QUV).

• Okpomọkụ dị nso: -50°C ruo +150°C.

• Ike dielectric dị elu (20-30 kV / mm) na enweghị ike mmiri.

• Obere gas permeability.

Uru:

• Emebere ya nke ọma na antioxidants na UV stabilizers.

• Mmanya ịma jijiji mara mma (ihe na-efu: 0.1-0.3).

Ngwa:

• Akụrụngwa: Akàrà ọnụ ụzọ, ọkpọkọ radiator, na igwe njin.

• Ihe owuwu: mkpuchi mkpuchi ụlọ, akwa ọdọ mmiri, na gaskets windo.

• Eletriki: Igwe mkpuchi eriri na eriri nnyefe ike.

5. Ngwakọta MPU (MPU)

Njirimara:

• Ike ike dị elu (20-60 MPa) na elasticity (ruo 800% elongation).

• Nguzogide abrasion pụrụiche (ASTM D5963: mfu 20–50 mm³).

• Okpomọkụ dị nso: -40°C ruo +100°C (ruo +120°C nwere ihe nkwụsi ike ọkụ).

• Na-eguzogide ihe mgbaze na hydrolysis.

Uru:

• Isi ike nwere ike ịhazi ya (Oké Osimiri A 50–95).

• Dị na nkedo, igwe igwe, ma ọ bụ akara thermoplastic.

Ngwa:

• Ụlọ ọrụ mmepụta ihe: wiil, rollers, na eriri ebufe.

• Ụgbọala: Nkwusioru nkwusioru, ihe na-awụ akpata oyi n'ahụ, na akpụkpọ ụkwụ nkwonkwo CV.

• Ahụike: Catheters, ihe nkwado orthopedic, na prosthetics.

6. Ngwakọta ACM (ACM)

Njirimara:

• Okpomọkụ na-aga n'ihu ruo +150°C (na-adịte aka +175°C).

• Nguzogide dị oke mma maka mmiri nnyefe akpaaka (ATF), mmanụ na okpomọkụ.

• Ozone na-agafeghị oke na nguzogide ihu igwe.

• Ike nkwụsị: 7–15 MPa.

Uru:

• Ejikọtara ya na amine ma ọ bụ peroxide curatives maka ọgwụgwọ ngwa ngwa.

• Na-edobe nkwụsi ike akụkụ na gburugburu ATF.

Ngwa:

• Ụgbọala: Akara nnyefe, O-mgbanaka, na diaphragms mgbapụta.

• Akụrụngwa sistemu ike.

• Ụlọ ọrụ mmepụta ihe: Mgbapụta mgbapụta maka mgbasa ozi dabeere na mmanụ.

7. Ngwakọta AEM (AEM)

Njirimara:
