Faahfaahinta Alaabta
HFC eps waxay ka kooban tahay kuul madow oo yar yar oo polystyrene (EPS) ah oo ay ku jiraan walxo afuufaya, taas oo ka dhigaysa mid la fidin karo.
HFC eps waa kobcinta hal-abuurka leh ee dahaarka eps-ka caadiga ah waxayna horeyba u ahayd sumad xooggan ilaa 2012, taasoo bixisa dhammaan faa'iidooyinka asalka ah:

Waxqabadka HFC oo ka sii fiican xagga dhaqdhaqaaqa kulaylka
Saamaynta dahaarka ee aadka loo hagaajiyay waxaa lagu gaari karaa HFC, gaar ahaan cufnaanta cufnaanta aadka u hooseeya.Jaantusku waxa uu tusinayaa in agabka dahaadhka ee HFC cufnaanta cufnaanta 15 kg/m³ tusaale ahaan ay gaadhaan kulaylka 0.032 W/(m·K).EPS caadiga ah ee leh cufnaanta bulk isku mid ah, kuleylku waa 0.037 W/(m·K).

CODSIGA
HFC eps waxay leedahay dib u dhac holac oo aad u fiican, si sahlan loo farsameeyo iyada oo aan boodh lahayn oo aan waxyeello u geysan maqaarka, ka sokow, waxay sidoo kale ku soo celin kartaa isla saamaynta dahaarka leh guddi ka sii dhumuc weyn marka loo eego eps-ka caadiga ah, hoos u dhigista qiimaha si aad ah, sidoo kale, waxay kordhin kartaa cimriga dhismo.
