Application in Plastic Industries

The pearl effect pigment is translucent, you must pay attention to its optics capability and use it, then can bring excellent pearl effect pigment . The plastic industry develops rapidly in the world during the near several years, it is very important in the national economy of our country. With improvement and the development of plastic forming process method, and the rich and colorful of plastic products, the use of pearl effect pigment  in plastic industry is common. The pearl effect pigment  is used to increase the appeal in leatheroid, wallpaper, plastic packs, and cosmetics, the shampoo packs, man-made pearls, plastic buttons and other plastic products. The pearl effect pigment can be used in all hot plastics and some hot solid plastics. The thickness of the pearl effect pigment used in plastic lies on different use condition, but usually, only 1-2% (Occupation for pitch weight) can bring satisfying effect, but it will be to 4-8% thickness for some film products. On the other side, some plastics in low transparence will show the effect when using high-content pearl effect pigment or bigger particles.

Application field: Plastics container, packaging of cosmetic, shampoo, plastic soft tube for food and shampoo. Plastic fittings of bicycle and motorcycle. Electronic plastic instrument. Film, toy, commodity, decoration. Button ,Shoe Plastic Building material.

Instruction Suitable for being used in PE, PP, PS, PVC, PET, ABS, the better transparent of the plastic is, the better the pearl luster is. Good weather-resistance can meet the demand of different resin. For crystalline plastics, due to its crystalline structure, the pearl and metal effect pigment cannot be arranged in parallel. As a result, the effect will be weak. In this case, use the method of surface coating is a usual way. In order to avoid the final plastic product appearing the fold, the design of the casts mold should be very important. Application procedure. Pearl pigments should be mixed with a plastic material thoroughtly but gently. Some dispersant shoud be used at need When dispersing pearl pigments within plastic material, it is important to avoid overgrinding or overmilling, since this would fracture the plate-like flake structure into smaller light-scatering particles, producing less lustrous appearance. Insufficient dispersion of other colorants cause the particle size of other colorants to change due to pearl pigment. Cleaning condition of processing machines is also very important to application. If the cleaning condition of the molding machine is bad , when pearlized plastic material is flow in the molding machine, pearl pigment scrapes dust in molding machine, and this dust appears on the final product as foreign matter. Pearl pigment used in combination with other colorants in order to hide backgroud color and /or hide interior of the final product.(e.g. Bottles) For a good pearl luster effect, it is a very important factor to combine and /or balance between pearl pigment and other colorants. When using the backgroud layer,(e.g. Multilayer blow molding). It is important to check backgound color.
