Color of the year 2021

Color of the year 2021

For such expensive pigments like purple (violet) shades, our violet masterbatch reduces the expenses by its high dispersion and tinting strength. TPS provides you with high quality masterbatch based on different polymers useable in injection molding, blow molding, extrusion and similar processes. Pantone has chosen two shades for its Color of the Year 2021 The bright yellow shade, called Illuminating, is meant to evoke the optimistic promise of a sunshine-filled day , while Ultimate Gray is a much quieter hue that speaks more of composure, steadiness and resilience . Pantone says the colour can almost be compared to durable natural elements, like time-weathered pebbles on a beach ...

Carbon Black Pigment

Carbon Black Pigment

This article is mostly derived from the book “Coloring of Plastics: Fundamentals – Colorants – Preparations, chap.5” by Albrecht Müller. Carbon black (C) – Pigment black 7 / 77266 / CAS 1333.86.4 carbon black (CI pigment black 7) dominates the market for black shades. Black pigments are used either for pure black shades or for darkening of colored shades. Carbon black, pure carbon, is a very fine pigment with a very high tinting strength. Carbon black is classified as an inorganic pigment, for example in the German standard DIN 55944, in spite of the fact that carbon is one of the main components in the whole of organic chemistry. Carbon black is m ...

iron oxide

iron oxide

Manufacturing Process The Laux process Reaction of black: 9 Fe + 4 C6H5NO2 + 4 H2O 3 Fe3O4 + 4 C6H5NH2 Reaction of yellow: 2 Fe + C6H5NO2 + 2 H2O 2 FeO(OH) + C6H5NH2 Reaction of red: 2 Fe3O4 + ½ O2 3 Fe2O3 Initially, the Laux process was exclusively used to manufacture aniline (C6H5NH2) from nitrobenzene (C6H5NO2). Only when in 1925 the chemist, Dr Laux, found out that the iron oxide, being a by-product of this reaction, could be used, subject to certain chemical conditions, as an iron oxide pigment with extremely high colour strength. This process is primarily used for black iron oxide (e.g. Black 330), however, the reaction to get iron oxide yel ...

Organics vs. Inorganics – Are they different?

Organics vs. Inorganics – Are they different?

Organic pigments are synthetic materials based on carbon usually derived from petrochemicals. They generally are not stable at elevated temperatures and have partial solubility in strong solvents, but do not dissolve in water. Inorganic pigments are metal salts and oxides, some natural and some synthetic, that generally are stable at elevated temperatures and do not dissolve in solvents. Due to their stable chemical structures, most inorganic pigments have better weatherability, dispersibility and opacity than organic pigments, however they will typically have lower chromaticity and tinctorial strength. ...

Know All About Aluminum Powder

Know All About Aluminum Powder

Aluminum Element Aluminum is everywhere. It is the third most frequent chemical element on the earth and we can find it in almost everything we use every day. It is in the cars we drive, it is in the computers we work with and it is widely in our home appliances. 8 percent of the earth’s crust belongs to aluminum but you need to know that because of its great binding capabilities, we can’t find pure aluminum in nature commonly. While aluminum is a greatly flexible and light metal but it shows a lot of strength. Thanks to these valuable features, aluminum is a very popular metal that has a lot of use in different forms. Powdered Aluminum Aluminum powder can be made in ...
