Pu Safety Shoe Sole System
Pu Safety Shoe Sole System
IMAU OYAMBA
Dongosolo la PU Safety shoe-soli limagwiritsidwa ntchito popanga nsapato zachitetezo ndi zitsulo zamkati.Ndi polyester-based PU system material, ili ndi zigawo zinayi, polyol, ISO, hardner ndi chothandizira.The processing wa dongosolo ndi zigawo ziwiri.Chothandizira, cholimba, chowombera ndi pigment ziyenera kusakanikirana bwino ndi polyol chigawo EXD-3270A, kenaka sakanizani ndi gawo la ISO EXD-3119B popanga zinthu zomaliza.
