dyed PP

PP raw material is the abbreviation of polypropylene (Polypropylene), it is a kind of thermoplastic resin. Dyeing PP raw material refers to the material after coloring treatment by adding various pigments or dyes on the basis of polypropylene raw materials. This dyeing process can be achieved during the synthesis of PP raw materials (such as the addition of masterbatches in the polymerization stage), or after the production of PP raw materials, through secondary processing (such as the use of dip dyeing, spraying, etc.).
