Pu Safety Shoe Sole System
Pu Safety Shoe Sole System
IPambuka
Sistem sepatu-sole PU Safety digunakake kanggo nggawe outsoles sepatu safety lan soles jero.Iku bahan sistem PU basis polyester, kalebu papat komponen, polyol, ISO, hardner lan katalis.Pangolahan sistem kasebut ana rong komponen.Katalis, harder, agen ndamu lan pigmen kudu dicampur sak tenane karo komponen polyol EXD-3270A, banjur nyampur karo komponen ISO EXD-3119B kanggo nggawe barang pungkasan.
