Pu Safety Shoe Sole System
Pu Safety Shoe Sole System
IISINGENISO
I-PU Safety shoe-sole system isetshenziselwa ukwenza izihlangu eziphumayo zokuphepha kanye namasoli angaphakathi.Kuyi-polyester-based PU system material, iqukethe izingxenye ezine, i-polyol, i-ISO, i-hardner kanye ne-catalyst.Ukucutshungulwa kwesistimu kuyizingxenye ezimbili.I-catalyst, eqinile, i-ejenti evuthelayo kanye ne-pigment kufanele kuhlanganiswe kahle nengxenye ye-polyol EXD-3270A, bese ixutshwa nengxenye ye-ISO EXD-3119B yokwenza izinto zokugcina.
IZIMPAHLA ZOMZIMBA
