HFC eps imapangidwa ndi mikanda yaying'ono yakuda ya polystyrene (EPS) yomwe imakhala ndi chowombera, chomwe chimapangitsa kuti chiwonjezeke.
HFC eps ndi njira yabwino yopititsira patsogolo ma eps apamwamba otchinjiriza ndipo yakhala kale mtundu wamphamvu kuyambira 2012, yopereka maubwino onse apachiyambi:
Zofunikira zazikulu Pakati pa ma graphite ndi ma eps wamba oletsa moto

APPLICATION
HFC eps ili ndi mphamvu yabwino kwambiri yochepetsera moto, kukonza kosavuta popanda fumbi komanso kosavulaza khungu, kuonjezera apo, ingathenso kubwezeretsanso zomwezo ndi bolodi lakuda kuposa ma eps wamba, kuchepetsa mtengo kwambiri, kuonjezera apo, imatha kukulitsa moyo wa kumanga.
