Okokuqala, kufuneka ufumanise ukuba kukho ingxaki na ngearhente ekhethiweyo yokufutha. Isilawuli se-PVC foam sisebenzisa iarhente yokufutha ukubola nokuvelisa igesi ebangela iimbobo. Xa ubushushu bokucubungula bunokufikelela kubushushu bokubola kwearhente yokufutha, ngokwemvelo ayizukufutha. Iindidi ezahlukeneyo zeearhente zokufutha zinobushushu obahlukeneyo bokubola, nokuba uhlobo olufanayo lwearhente yokufutha lwenziwa ngabavelisi abahlukeneyo, ubushushu bokubola busenokungafani ncam. Khetha isilawuli se-PVC foam esifanelekileyo kuwe. Ayizizo zonke iiPVC ezifanelekileyo ukufutha, ngoko ke kuyimfuneko ukukhetha izixhobo ezinezinga eliphantsi le-polymerization. Ezi zinto zinobushushu obuphantsi bokucubungula, njenge-S700. Ukuba ufuna ukusebenzisa i-1000 kunye ne-700, isenokuba yahlukile. Iarhente yokufutha isenokuba sele ibolile kwaye i-PVC ayikanyibiliki.
Ukongeza, kukho ezinye izongezo. Ubushushu bokubola kwearhente eqhelekileyo yokufutha buphezulu kunobushushu bokucubungula bePVC. Ukuba izongezo ezifanelekileyo azongezwanga, isiphumo kukuba iPVC iyabola (ijika ibe mthubi okanye ibe mnyama) kwaye i-ACR ayikaboli (amagwebu). Ke ngoko, kuyimfuneko ukongeza iziqinisi ukugcina iPVC izinzile (ayiboli kubushushu bovavanyo be-AC). Kwelinye icala, izongezo ezikhuthaza ukufutha kwe-AC zongezwa ukunciphisa ubushushu bokubola kwe-AC kwaye zihambelane nayo. Kukwakho nezongezo zokwenza ii-foam pores zibe ncinci kwaye zixineneyo, oku kukuphepha ii-foam pores ezinkulu eziqhubekayo nokunciphisa amandla emveliso. Ekubeni ubushushu buphantsi kwaye bungasabi mthubi, ndingaqinisekisa ukuba ubushushu bakho obuphezulu bangaphambili bubangele ukuba iPVC ibole kwaye ibe mthubi. Ukufutha kwePVC yindlela yokuzikhuthaza, oko kuthetha ukuba izinto ezibolileyo zikhuthaza ukufutha ngakumbi. Ke ngoko, kuhlala kubonakala ukuba kulungile ukuba ubushushu abuphezulu, kodwa ukuba ubushushu buphezulu kancinci, buya kubola ngobuninzi.
