Ukususela kwi-2016 ukuya kwi-2020, ukunikezelwa kunye nokufunwa kweemarike ze-cyclopentane zasekhaya zanda unyaka nonyaka, kwaye imarike yasekhaya ye-cyclopentane yayikwimeko yophuhliso olulinganayo.Esona sizathu siphambili sokunyuka okuhambelanayo kobonelelo lwe-cyclopentane kunye nemfuno kule minyaka yakutsha nje kukupheliswa ngokuthe ngcembe kweearhente zogwebu zeHCFC kunye nokuphuculwa kwemarike yearhente yogwebu lwasekhaya.I-agent ye-cyclopentane enegwebu lenze uphuhliso oluhle kwintsimi ye-polyurethane foam eqinile kunye nokusebenza kwayo okugqwesileyo kunye neenzuzo zexabiso.
Ngo-2020, amandla okuvelisa i-cyclopentane yaseChina (iyunithi yokuhlukana kakuhle) iya kufikelela kwiitoni ze-342000 / ngonyaka, umphumo uya kufikelela kwiitoni ze-97000, kwaye ukusetyenziswa okubonakalayo kuya kufikelela kwiitoni ze-85000.
Ukusukela ngo-2016 ukuya ku-2019, ukubonelela kunye nemfuno yemarike yasekhaya ye-cyclopentane yanda unyaka nonyaka.Ukususela ekusebenzeni kokunikezelwa kwe-cyclopentane yasekhaya kunye nemfuno, imarike ye-cyclopentane yasekhaya iqhubekile ibe kwimeko yophuhliso olulinganayo phakathi kokubonelela kunye nemfuno kwi-2015-2019.Ngo-2020, unikezelo lwemarike ye-cyclopentane kunye nemfuno esezantsi yomlambo ichatshazelwa kwinqanaba elithile yi-COVID-19, kwaye iyancipha.
I-Cyclopentane isetyenziswa kakhulu njenge-arhente entsha yogwebu lwe-polyurethane foam eqinile.Isetyenziswe ngokubanzi kwimveliso yeefriji zasimahla ze-fluorine, izikhenkcisi, iindonga zesakhiwo sangaphandle, ukugquma ukugcinwa okubandayo, izikhongozeli ezifakwe efrijini, ukugqunywa kwemibhobho kunye nezinye iindawo, kunye nenani elincinci leemveliso ezisetyenziswa kwimveliso yamayeza aphakathi amayeza.
Ngokukhawuleza ngokuthe ngcembe kwenkqubo yokuphelisa iHCFC, itekhnoloji ye-polyurethane egwebu amagwebu iya kungena kwixesha lokuphucula, kwaye unikezelo lwamashishini emveliso ye-cyclopentane kusalindeleke ukuba lunyuke ngenxa yokunyuswa kwengeniso ephezulu, iarhente yokusingqongileyo enogwebu ye-pentane iya kuthi. ukubamba inxalenye yesabelo semalike ye-HCFC ye-arhente yogwebu, kwaye kulindeleke ukuba imfuno yemarike ye-cyclopentane yaseChina iya kwanda kwiminyaka eyi-3-5 ezayo.
