Masterbatch is a new type of special colorant for polymer materials composed of pigments or dyes, carriers and additives.
1. Basic concepts and composition of masterbatch
Masterbatch is a new type of special colorant for polymer materials. It mainly consists of three basic elements: pigments or dyes, carriers and additives. Pigments or dyes give the masterbatch a rich variety of colors, which can meet the different color needs of various products, from bright and eye-catching to soft and elegant, covering almost the entire visible spectrum range.
2. Salient features of masterbatch
(1) High tinting strength and uniformity
The pigments in the masterbatch are carefully selected and specially treated to have extremely high tinting power. This means that only a small amount of masterbatch is needed to achieve the desired color depth for plastic products.
(2) Good stability
Masterbatch can show excellent stability under different environmental conditions. It can withstand the influence of high temperature, light, humidity and other factors without fading or discoloration. For example, plastic products used outdoors, such as building materials, auto parts, etc., need to be exposed to sunlight, wind and rain for a long time. The stability of the masterbatch can ensure that the colors of these products remain bright and new during long-term use.
(3) Environmental protection and safety
As people's awareness of environmental protection and product safety continues to increase, the advantages of masterbatch in environmental protection and safety have become increasingly prominent. The production process of modern masterbatch strictly follows environmental protection standards, using non-toxic and odorless raw materials, without harmful heavy metals and other harmful substances, and conforms to industry standards with extremely high safety requirements such as food packaging and medical devices.
3. Wide application areas of masterbatch
(1) Plastic industry
Plastic is one of the most important application fields of masterbatch. Almost all types of plastic products can be colored with masterbatch, from common daily necessities such as plastic tableware, toys, stationery, etc., to plastic pipes, plastic sheets, plastic films, etc. in the industrial field.
(2) Chemical fiber industry
In the field of chemical fiber, masterbatch also plays an important role. It is widely used in the coloring of synthetic fibers, such as polyester fiber, nylon fiber, polypropylene fiber, etc. By mixing masterbatch with chemical fiber raw materials before spinning, colorful colored fibers can be produced.
(3) Rubber industry
The coloring of rubber products is also inseparable from masterbatch. Whether it is natural rubber or synthetic rubber, the desired color can be obtained by adding masterbatch. In the production process of rubber products, masterbatch and rubber raw materials are fully mixed during the mixing stage, and then go through processes such as vulcanization and molding to make rubber products of various colors, such as tires, rubber seals, rubber soles, etc.
(4) Other fields
In addition to the above three main fields, masterbatch is also widely used in many other industries. In the coating industry, masterbatch can be used as a pigment additive to produce various colored coatings to provide colorful exterior decoration for buildings, furniture, automobiles, etc.
In the ink industry, masterbatch can provide bright and stable colors for printing inks to meet the needs of different printing processes and printed matter, such as paper printing, plastic printing, metal printing, etc.
In the electronic and electrical industry, some plastic shells, wires and cables and other parts need to be colored with masterbatch. At the same time, masterbatch with special functions can also be added, such as conductive masterbatch, antistatic masterbatch, etc., to meet the needs of the product. Requirements in terms of electromagnetic shielding and electrostatic protection.
In addition, masterbatch is increasingly used in fields with high health and safety requirements such as cosmetic packaging, medical equipment, and food packaging, providing a strong guarantee for improving the appearance and performance of these products.
