• Zotsika mtengo komanso zowoneka bwino kwambiri.

• Customizable acrylonitrile content (18-50%) ya kukana mafuta ogwirizana.

Mapulogalamu:

• Magalimoto: Mapaipi amafuta, mphete za O, ndi zisindikizo zotumizira.

• Mafakitale: Malamba onyamula, zodzigudubuza, ndi zisindikizo zama hydraulic.

• Ogula: Magolovesi a latex ndi zida zamasewera.

4. EPDM Compound (Ethylene Propylene Diene Monomer)

Katundu:

• Kukaniza kwa ozoni / nyengo (maola 5,000+ pakuyesa kwa QUV).

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

• Mphamvu ya dielectric yapamwamba (20-30 kV/mm) ndi kusakwanira kwamadzi.

• Low mpweya permeability.

Ubwino:

• Opangidwa kale ndi antioxidants ndi UV stabilizers.

• Kugwedera kwabwino kwambiri (chotayika: 0.1-0.3).

Mapulogalamu:

• Magalimoto: Zisindikizo za zitseko, mapaipi a radiator, ndi zoyikira injini.

• Kumanga: Zotchingira denga, zomangira dziwe, ndi gaskets zamawindo.

• Zamagetsi: Kutsekereza ma chingwe ndi malamba otumizira mphamvu.

5. MPU Compound (MPU)

Katundu:

• Kulimba kwamphamvu kwambiri (20-60 MPa) ndi kukhazikika (mpaka 800% elongation).

• Kukana kwapadera kwa abrasion (ASTM D5963: 20-50 mm³ kutayika).

• Kutentha kwamitundu: -40 ° C mpaka +100 ° C (mpaka +120 ° C ndi zowongolera kutentha).

• Kugonjetsedwa ndi solvents ndi hydrolysis.

Ubwino:

• Kuuma kosinthika (Shore A 50–95).

• Amapezeka m'magalasi opangidwa ndi cast, millable, kapena thermoplastic.

Mapulogalamu:

• Industrial: Mawilo, ma roller, ndi malamba onyamula katundu.

• Zagalimoto: Zoyimitsidwa tchire, zotsekera zoziziritsa kukhosi, ndi nsapato za CV.

• Zachipatala: Ma catheters, zingwe za mafupa, ndi ma prosthetics.

6. ACM Compound (ACM)

Katundu:

• Kutentha kosalekeza mpaka +150 ° C (kwapakatikati + 175 ° C).

• Kukana kwabwino kwamadzimadzi opatsirana (ATF), mafuta, ndi kutentha.

• Ozone yokhazikika komanso kukana kwanyengo.

• Mphamvu yamphamvu: 7-15 MPa.

Ubwino:

• Osakanizidwa kale ndi mankhwala a amine kapena peroxide kuti achire mwachangu.

• Imasunga kukhazikika m'malo a ATF.

Mapulogalamu:

• Magalimoto: Zisindikizo zotumizira, mphete za O, ndi ma diaphragms opopera.

• Zida zowongolera mphamvu zamagetsi.

• Industrial: Pampu zosindikizira za media zotengera mafuta.

7. AEM Compound (AEM)

Katundu:
