When buying paint additives for plastic, buyers consider various factors. Here are the factors they consider:
Compatibility with Plastics
When selecting pigments for plastics, buyers assess the pigments' compatibility with various plastic resins. Commonly, plastics used are polyethylene, polypropylene, and polyvinyl chloride. Each plastic has unique characteristics, the pigments should blend well with the plastic matrix. This ensures uniform coloration and avoids issues like settling or separation. To get the right pigment, buyers should consult the manufacturers' recommendations. They should also keep in mind that organic pigments are suitable for plastics that require bright color and high transparency. On the other hand, inorganic pigments work better on plastics that have high stability and UV exposure.
Tinctorial Strength
Tinctorial strength is another factor buyers consider. They use it to determine the capacity of a pigment to impart color to a resin. Basically, higher tinctorial strength means that a small amount of pigment can immobilize a large amount of color. Buyers use color matching systems to measure this attribute. Usually, these systems offer data that enable users to select pigments that meet their required intensity. In cases where they must use a dropdown of pigments with the same tinctorial strength, they ensure that one has better lightfastness and chemical stability.
Regulatory Compliance
At this stage, buyers ensure that pigments comply with necessary regulations. Often, these regulations include REACH and the Toxic Substances Control Act. Normally, these regulations ensure that manufacturers have a safe workplace environment.
