Loaʻa iā ia nā hiʻohiʻona o ke kulou ikaika maikaʻi, ka hana anti-cracking maikaʻi, ka hana ozone maikaʻi loa, ka pale ʻana i ka wā kahiko, ka pale ʻana i ka wela, ke kūpaʻa aila, ka pale ʻana a me nā mea ʻē aʻe. Hoʻohana nui ʻia ke kāʻei synchronous Chloroprene i ka textile, kaʻa kaʻa, fiber chemical, cigarette, papermaking, paʻi, mīkini a me nā mea hana; I kēia mau makahiki i hala iho nei, ke hoʻonui nei ka noiʻi ʻana i ka metallurgy, ka hao a me ka mīkini kila.

Wahi a ka mea, hiki ke hoʻokaʻawale ʻia ke kāʻei synchronous i loko o ke kāʻei neoprene a me ke kaula fiber synchronous kāʻei, polyurethane a me ke kaula kila synchronous kāʻei. Wahi a ke ʻano o nā niho, ua māhele nui ʻia i nā niho trapezoidal a me nā niho arc. E like me ka hoʻolālā o nā niho, hiki ke hoʻokaʻawale ʻia i ke kāʻei synchronous niho ʻaoʻao hoʻokahi a me ke kāʻei synchronous niho ʻaoʻao ʻelua.

ʻO ke kāʻei ke kūpaʻa flexure maikaʻi loa, ka elongation liʻiliʻi, ka ikaika kiʻekiʻe, akā loaʻa pū kekahi i ka pale ʻana i ka aila, ka wela wela, ke kūʻokoʻa o ka wā kahiko, ka pale ozone, ka pale ʻana a me nā waiwai maikaʻi ʻē aʻe. ʻO ke kāʻei synchronous i kēia manawa ma mua o 30 mau hiʻohiʻona, ʻoi aku ma mua o 1000 mau kikoʻī, a me ke kākoʻo ʻana i ka huila kāʻei synchronous, ma waho aʻe o nā hiʻohiʻona maʻamau, akā no nā mea hoʻohana e hoʻolālā a hana i nā kikoʻī kūikawā o ke kāʻei synchronous, e hoʻokō i nā koi kūikawā o nā mea hoʻohana.

Hana ʻo Annai i nā ʻano hana kāʻei like ʻole, nā hiʻohiʻona kikoʻī: 2M, 3M, 5M, 8M, 14M, 20M, H, L, MXL, P2M, P3M, P3M, P5M, P8M, P14M, S2M, S3M, S4.5M, S5M, S4.5M, S5M, S4.5M, S5M, S5M T10, T20, XH, XL, XXH a pela aku.
