Plastic is a polymer compound that uses monomers as raw material and is polymerized by addition or polycondensation. Its resistance to deformation is moderate, between fibers and rubber. It is composed of additives such as synthetic resin, filler, plasticizer, stabilizer, lubricant and colorants. The colorant used in plastic coloring are generally inorganic pigment, organic pigment and solvent dye. There are many varieties of organic pigment and it has bright color and high tinting strength so that other pigments cannot replace its superiority. Thus, the importance of organic pigment in plastic coloring is obvious. In addition to powder, pigments can also be made into color masterbatches, prefabricated products to color plastic.
Commonly used colored plastics are as follows: PE-polyethylene LDPE-Low Density Polyethylene LLDPE - Linear Low Density Polyethylene HDPE-High Density Polyethylene PP-Polypropylene PVC-polyvinyl chloride PS-Polystyrene PC-polycarbonate PA66-nylon PET-polyethylene terephthalate PBT-polybutylene terephthalate PMMA-polymethacrylate EVA-ethylene-vinyl acetate copolymer POM-polyoxymethylene ester PU-polyurethane ABS-acrylonitrile-butadiene-styrene copolymer
There are many colored plastic products: shopping plastic bags, plastic storage boxes, plastic buckets, plastic bowls, plastic bottles, plastic tubes, plastic slippers, car bumpers, car plastic interiors, etc.
