Faahfaahinta Alaabta
HFC eps waxay ka kooban tahay kuul madow oo yaryar oo polystyrene ah (EPS) oo ay ku jiraan walxaha afuufaya, taas oo ka dhigaysa mid la ballaarin karo. Kiimikada ugu yar ayaa soo saarta walxahan gaarka ah, kaas oo lagu farsameeyo soosaarayaasha xumbo-soo-saarka alaabada dahaarka ee codsiyada kala duwan ee kala duwan.
HFC eps waa kobcinta hal-abuurka leh ee dahaarka eps-ka caadiga ah waxayna horey u ahayd astaan xooggan ilaa 2012, oo bixisa dhammaan faa'iidooyinka asalka ah:
Qiyaasaha ugu muhiimsan ee u dhexeeya graphite iyo eps dab-demiska caadiga ah
| Isbarbardhigga | Garaafka darajada (HFC) | Dab damiska cad (F) |
| Qiimaynta dabka | B1 | B2 |

| Cufnaanta (g/l) | 14-35 | 12-30 |
| Isku-dhafka kulaylka conductivity w/(mk) | ≤0.032 | ≤0.041 |
| Awood cadaadis (mpa) | ≥0.10 | ≥0.06 |
| nuugista biyaha | ≤2% | ≤2% |
| Tusmada Ogsajiinta | ≥30 | ≥30 |
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 nolosha dhismo.
