Organic or Inorganic

The pigments for plastic are present in large part of our life. Almost any everyday, at least one object that you use is stayned with these dyes, just excepting some objects made of wood and metal, From the board of our car to the bottle from which we drink contain tones, and even, tactile properties, quite particular. These qualities are the product of organic and inorganic components.

Advantages and disadvantages of the inorganic pigments

 

Inorganic pigments have a number of positive properties if you want to achieve a quality results. When applied to the polymers, these are more resistant to heat and to the open air. Its price is also competitive, as it can be economic, or at least more accessible than other types of dyes for plastic. These are also ideal for coloring sheets of calendering. However, despite its qualities, this type of dyes also has its cons.

 

The inorganic pigments are chromatically limited. , for example, It can achieve a good tonality. Can only achieve this by mixing with organic dyes. The latter, in addition, contain more variety of colors. But, beyond the elements that affect the quality or variety, there is another issue perhaps larger: the lead salts, present in their chemical composition THAT are increasingly under attack for ecological reasons.

 

Pros and cons of organic pigments

 

Organic pigments have a number of advantages and disadvantages depending on the variety to which they belong. In general, tend to be resistant to the heat and light. Another common element is the absence of heavy metals, considered enemies of the environment. These features are presented in chemical components such as Chrome Oxide Green, chrome yellow or cobalt salts. Each one of them has strengths applicable to very specific things.

 

In comparison with the inorganic pigments, the biggest advantage continues to be the environmental factor. However, the organic pigments have still not achieved the opacity necessary for certain products. The disadvantages are related more to particular characteristics of each type of dye. The Chrome Oxide Green, for example, limits its range to green tones, while the ultramarine pigments (blue and violet) are lack of opacity, which does not rule out its utility if you want to achieve a semi-transparent tone.

 

If we speak about the ecological theme, it’s always the best to use organic dyes, while the inorganic are justified in really necessary cases. From the board of our car to the bottle from which we drink contain tones, and even, tactile properties, quite particular. These qualities are the product of organic and inorganic components.
