Pu Safety Shoe Sole System
Pu Safety Shoe Sole System
ISUMO
PU Chengetedza bhutsu-sole sisitimu inoshandiswa kugadzira shangu dzekuchengetedza shangu uye dzemukati soles.Iyo polyester-yakavakirwa PU system zvinhu, ine zvikamu zvina, polyol, ISO, hardner uye catalyst.Kugadziriswa kwehurongwa zvikamu zviviri.The catalyst, harder, blowing agent uye pigment inofanira kunyatsosanganiswa ne polyol component EXD-3270A, wozosanganisa ne ISO chikamu EXD-3119B pakugadzira zvinhu zvekupedzisira.
