Selection of pearlescent pigment materials

Material selection

1 Since the pearlescent pigment itself is translucent and needs to rely on external light reflection to achieve a good pearlescent effect, when choosing plastics, materials with better transparency should be used as much as possible. The following plastics are more commonly used, and their common point is that they are relatively transparent. After adding pearlescent pigments, light can pass through the surface plastic to reach the surface of the pearlescent pigment chip and cause reflection and refraction. Polyethylene HDPE, LDPE (film), polypropylene PP, modified polyethylene EVA, acrylic PMMA, saturated polyester PET, polycarbonate PC, polyvinyl chloride PVC, unsaturated polyester Like AK, epoxy resin EPT, polyurethane PU, low transparency or opaque plastics, such as GPPS, HIPS, ABS, etc., the pearlescent effect is not obvious, but this does not mean that these plastics cannot use pearlescent pigments, but pearlescent The amount of pigment is relatively large. Pearlescent Pigment

2 In terms of the choice of mixed pigments, pearlescent pigments cannot be mixed with conventional opaque pigments (such as chromium, cadmium pigments, titanium dioxide).

Pearlescent pigments can be used for transparent and translucent plastic resins. The use of pearlescent pigments will bring a charming color visual effect. Pearlescent pigments are widely used in cosmetic containers, various packaging, toys, decorative materials, various films and other plastic products.
