Neoprene, wotchedwanso mphira wa chloroprene ndi Xinping rabara. Rabara yopangidwa ndi α-polymerization ya chloroprene (2- chloro -1,3- butadiene) imagwiritsidwa ntchito kwambiri pazinthu zanyengo, ma viscose soles, zokutira ndi mafuta a rocket.

Chophimba kapena chipika chokhala ndi zoyera zamkaka, beige kapena zofiirira zowoneka bwino ndi elastomer yopangidwa ndi alpha polymerization ya chloroprene (ie 2- chloro -1,3- butadiene) ngati chopangira chachikulu. The solubility parameter wa mphira wa chloroprene amawerengera δ = 9.2 ~ 9.41. Amasungunuka mu toluene, xylene, dichloroethane ndi vanadium ethylene, sungunuka pang'ono mu acetone, methyl ethyl ketone, ethyl acetate ndi cyclohexane, osasungunuka mu n-hexane ndi mafuta osungunulira, koma amasungunuka mu zosungunulira zosakanikirana zopangidwa ndi zosungunulira zabwino komanso zosungunulira zoyipa komanso zosasungunuka. kapena zosungunulira zoipa ndi zosasungunuka moyenerera, kutupa mumafuta a masamba ndi mafuta amchere koma osasungunuka.

Zabwino zakuthupi komanso zamakina, kukana kwamafuta, kukana kutentha, kukana moto, kukana kuwala kwa dzuwa, kukana kwa ozoni, kukana kwa asidi ndi alkali komanso kukana kwa reagent. Zoyipa ndizosauka kuzizira komanso kukhazikika kosungirako. Ili ndi mphamvu zolimba kwambiri, elongation, crystallinity yosinthika komanso kumamatira kwabwino. Kukana kukalamba ndi kukana kutentha. Kukana mafuta abwino kwambiri komanso kukana kwa corrosion chemical. Kukana kwanyengo ndi kukana kukalamba kwa ozone ndizochiwiri kwa mphira wa ethylene propylene ndi mphira wa butyl. Kukana kutentha ndi kofanana ndi mphira wa nitrile, ndi kutentha kwa 230 ~ 260 ℃, kukana kwakanthawi kochepa kwa 120 ~ 150 ℃, kugwiritsa ntchito nthawi yayitali pa 80 ~ 100 ℃, ndi kuchedwa kwina kwamoto. Kukana kwamafuta ndikwachiwiri kwa rabara ya nitrile. Kukana kwa dzimbiri kwa inorganic acid ndi alkali. Kusazizira bwino komanso kutsekeka kwamagetsi kosakwanira. Kukhazikika kosungirako kwa mphira yaiwisi kumakhala kosauka, zomwe zimatsogolera ku zochitika za "self-sulfure". Kukhuthala kwa Mooney kumawonjezeka ndipo mphira waiwisi umauma. Mitundu yakunja ikuphatikizapo AD-30 (USA), A-90 (Japan), 320 (Germany) ndi MA40S (France).

CR122 chloroprene rabara: Zopangira mphira monga malamba otumizira, malamba oyendera, mawaya ndi zingwe, mapepala amphira osagwira mafuta, mapaipi a rabara osamva mafuta ndi zida zomata.

CR122 chloroprene rabara: Zopangira mphira monga malamba otumizira, malamba oyendera, mawaya ndi zingwe, mapepala amphira osagwira mafuta, mapaipi a rabara osamva mafuta ndi zida zomata.

CR232 chloroprene rabara: chingwe m'chimake, mafuta zosagwira mphira payipi, mphira chisindikizo, zomatira, etc.

Mtengo wa CR2441 2442 chloroprene rabara: zopangira zomatira, zomwe zimagwiritsidwa ntchito polumikizira zitsulo, matabwa, mphira, zikopa ndi zinthu zina.

CR321 322 mtundu wa mphira wa chloroprene: chingwe, bolodi la rabara, payipi ya rabara wamba komanso yosagwira mafuta, nsapato za mphira zosagwira mafuta, chopondera champhepo, poncho, nsalu ya hema, lamba wotumizira, lamba wonyamula, chisindikizo cha rabala, kapusi yaulimi, bwato lopulumutsa moyo, etc. Ntchito ngati toughening wothandizira wa kusinthidwa acrylate kudya structural zomatira (SGA).
