Pu Safety Shoe Sole System
Pu Safety Shoe Sole System
ISUMO
PU Chengetedza shangu-sole system inoshandiswa kugadzira shangu dzekuchengetedza kunze uye mukati me 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.
