Nowadays, the use of masterbatches is increasing for various reasons such as improving the dispersion and distribution of particles, high-quality products, reducing consumption costs, maintaining the health of staff, etc. Pearlescent pigments are a special kind of natural or synthetic materials that are divided into two categories without a substrate (bismuth oxychloride, iron mica oxide, and titanium dioxide sheets) and a coated substrate (natural mica coated with Metal oxides such as titanium dioxide, iron oxide, and aluminum oxide) are divided. Pearlescent pigments due to their special properties such as creating different colors by changing the angle of view, high heat resistance, high resistance to penetration, and brilliance in the form of pearlescent masterbatches in various industries such as plastic and packaging industries. It is used in cosmetics, automotive, textile, etc. Masterbatches are concentrated compounds that are added to polymers to make the color, improve its properties, and also reduce the cost of products during production. Masterbatch consists of three components: polymer, pigment or filler, and compatibilizing agent. There are various methods for making masterbatches, the most common method of which is the use of extruders (generally twin screw extruders). To make a masterbatch using extruders, mainly 3 methods of pre-mixing, divided feeding, and color matching are used. In this research, an internal mixer (Banbury) was also used to make the masterbatch. The purpose of this research is to investigate pearl pigments, general methods of making plastic masterbatches, methods of making pearl masterbatches, and their applications in different industries.
