• Pono:

• ʻO ke kumu kūʻai me ka hana maʻalahi (extrusion/molding).

• ʻO ka ikaika mechanical kiʻekiʻe a me ke kū'ē abrasion.

• Nā noi:

• Nā lole pulu, nā mīkina lima, a me nā paipu hana.

• Hoʻopili no nā kāmaʻa a me ke kūkulu ʻana.

• ʻO nā ʻaʻahu uwea a me nā membrane o luna.

3. ʻO ka Rubber Nitrile Hydrogenated (HNBR)

• Nā waiwai:

• Hoʻonui i ka pale wela (a hiki i +150 ° C) i hoʻohālikelike ʻia me NBR.

• ʻO ke kūpaʻa kiʻekiʻe i nā aila, nā wai hydraulic, a me nā amine.

• Ka ikaika tensile kiʻekiʻe a me ke kūpaʻa luhi.

• Haʻahaʻa haʻahaʻa i nā kinoea.

• Pono:

• Hoʻopaʻa i ka elasticity ma lalo o ka ʻike lōʻihi i nā kemika paʻakikī.

• ʻOi aku ka lōʻihi o ke ola ma mua o ka NBR i nā kūlana koʻikoʻi.

• Nā noi:

• ʻO nā mea hana wili ʻaila a me ke kinoea (packer, sila).

• ʻO nā kāʻei manawa kaʻa, nā mea hoʻoheheʻe wahie, a me nā sila turbocharger.

• ʻOihana hydraulic cylinders.

4. ʻO ka Rubber Silicone (VMQ)

• Nā waiwai:

• ʻO ke ana wela ākea ākea (-60°C a +200°C).

• Elasticity kiʻekiʻe (a hiki i 1000% elongation).

• ʻOi aku ka maikaʻi o ka pale uila a me ka paʻa wela.

• Biocompatible a inert.

• Pono:

• Mālama i ka maʻalahi i ka cryogenic a me ka wela wela.

• Kū'ē i ka UV, ka ozone, a me ka wā.

• Nā noi:

• Nā mea lapaʻau (catheters, implants).

• Nā mea uila (insulators, keypads).

• ʻO nā kīʻaha wela wela no nā umu a me nā ʻenekini.

5. ʻO ka Rubber Fluorosilicone (FVMQ)

• Nā waiwai:

• Hoʻohui i ka pale kemika o FKM a me ka maʻalahi o VMQ.

• Kaulana wela: -50°C a i +230°C.

• Kū'ē i nā wahie, nā lubricants, a me nā wai hydraulic.

• Hoʻonohonoho hoʻoemi haʻahaʻa a me ke kūpaʻa maikaʻi.

• Pono:

• Hana ʻia ma ka wela wela a me ka wela haʻahaʻa.

• Kū'ē i ka pehu i nā wahie lele.

• Nā noi:

• ʻO nā mea ʻōnaehana wahie mokulele (valves, sila).

• ʻO nā gaskets submersible hohonu a me nā mea hoʻohui.

• Nā ʻōnaehana kaʻa a me nā ʻōnaehana hoʻokuʻu.

6. Ethylene Propylene Diene Monomer (EPDM)

• Nā waiwai:

• ʻO ka ozone maikaʻi a me ka pale ʻana i ka wā.

• Ka ikaika dielectric kiʻekiʻe a me ka pale wai.

• Kaulana wela: -50°C a i +150°C.
