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.
