Pu Safety Shoe Sole System
Pu Safety Shoe Sole System
IENTWODIKSYON
PU Sekirite soulye-sèl sistèm yo itilize pou fè smèl soulye sekirite ak plant enteryè.Li se materyèl sistèm Polyester ki baze sou PU, konpoze de kat konpozan, polyol, ISO, hardner ak katalis.Pwosesis la nan sistèm nan se de eleman.Katalis la, pi rèd, ajan mouche ak pigman yo ta dwe melanje byen ak eleman nan polyol EXD-3270A, Lè sa a, melanje ak eleman ISO EXD-3119B pou fè machandiz final la.
