Advantages of color masterbatch and introduction to basic knowledge of color masterbatch

what is color masterbatch? Why use color masterbatch

masterbatch is an aggregate made by uniformly attaching super constant pigments to resins

using color masterbatch has the following advantages:

1 Make the pigment have better dispersibility in the products

in the production process of masterbatch, the pigment must be refined to improve the dispersion and coloring power of the pigment. The carrier of the special color masterbatch is the same as the plastic of the product, which has good matching. After heating and melting, the pigment particles can be well dispersed in the plastic of the product

2. It is conducive to maintaining the chemical stability of pigments

If pigments are directly used, because pigments are directly in contact with air during storage and use, pigments will absorb water, oxidize and other phenomena. After making color masterbatch, because resin carrier separates pigments from air and water, the quality of pigments can remain unchanged for a long time

3. Ensure the stability of the product color

the masterbatch particles are similar to the resin particles, which is more convenient and accurate in measurement. When mixing, they will not adhere to the container, and the mixing with the resin is more uniform. Therefore, the stability of the addition amount can be guaranteed, so as to ensure the stability of the product color

4. Protect the health of operators

pigments are generally powdery, which are easy to fly when added and mixed, and will affect the health of operators after being inhaled by human body

5. Keep the environment clean

6 Easy to use

What are the basic ingredients of Color Masterbatch

the basic components of color masterbatch are:

1 Pigments or dyes

pigments are also divided into organic pigments and inorganic pigments

common organic pigments include: phthalocyanine red, phthalocyanine blue, phthalocyanine green, sun resistant scarlet, macromolecular red, macromolecular yellow, YONGGU yellow, YONGGU purple, azo red, etc. Common inorganic pigments include: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

2 Carrier

is the matrix of color masterbatch. The special color masterbatch generally selects the same resin as the product resin as the carrier. The compatibility between the two is the best, but at the same time, the fluidity of the carrier should also be considered

3. Dispersant

makes the pigment disperse uniformly and no longer agglomerate. The melting point of dispersant should be lower than that of resin, which has good compatibility with resin and good affinity with pigment. The most commonly used dispersants are polyethylene low molecular wax and stearate

4. Additives

such as flame retardant, brightening and antibacterial. Purell kt mr07 (polybutylene ⑴) and Purell rp320m (polypropylene) materials produced by LyondellBasell company: Purell kt mr07 has excellent compatibility, antistatic, antioxidant and other varieties with polypropylene. Unless customers put forward requirements, the color masterbatch generally does not contain the above additives

what are the varieties and grades of Color Masterbatch

classification methods of color masterbatches are commonly used as follows:

classification by carrier: such as PE Color Masterbatch, PP Color Masterbatch, ABS Color Masterbatch, PVC color masterbatch, EVA Color Masterbatch, etc.

classification by purpose: such as injection Color Masterbatch, blow molding Color Masterbatch, spinning color masterbatch, etc. Each variety can be divided into different grades, such as:

1 Advanced injection Color Masterbatch

is used for cosmetic packaging boxes, toys, electrical appliance shells and other high-grade products

2. Ordinary injection Color Masterbatch

is used for general daily plastic products, industrial containers, etc

3. Advanced blown film color masterbatch

is used for blow molding coloring of ultra-thin products

4. Common blown film color masterbatch

is used for blow molding coloring of general packaging bags and woven bags

5. Spinning masterbatch

is used for spinning coloring of textile fibers. The masterbatch pigment has fine particles, high concentration, strong coloring power, and good heat and light resistance

6. Low grade color masterbatch

is used to manufacture low-grade products with low requirements for color quality, such as garbage cans, low-grade containers, etc

how to distinguish general color masterbatch from special color masterbatch

special color masterbatch: it is a color masterbatch made by selecting the same plastic as the carrier according to the plastic variety specified by the user for products. For example, PP masterbatch and ABS masterbatch use PP and ABS as carriers respectively

general color masterbatch: a certain resin (often PE with low melting point) is also used as the carrier, but it can be applied to the coloring of other resins except its carrier resin

general color masterbatch is relatively simple and convenient, but it has many disadvantages. It is recommended that you choose a special color masterbatch

why do many companies not produce general color masterbatches

most formal Color Masterbatch companies in the world generally do not produce general color masterbatches

universal color masterbatch has many disadvantages. In fact, the 'universal' scope of universal color masterbatch is very narrow, and its technical indicators and economic benefits are also poor, which is specifically reflected in:

1 Poor predictability of coloring effect

masterbatch is used for coloring. The pigments of general masterbatch will show different colors in different plastics, so the predictability of coloring effect is poor

2. It affects other properties of plastic products, especially the strength. The products are easy to deform and twist, which is more obvious for engineering plastics

3. High cost

in order to be 'universal', general color masterbatches often choose pigments with higher heat-resistant grades, resulting in waste

in addition to coloring, can the color masterbatch also have the functions of flame retardancy, brightening, antistatic, antioxidant 2017, UV resistance and so on

color masterbatch can have some of these functions at the same time, if the factory puts forward such requirements

sometimes, although the customer has not made a request, the color masterbatch company will also recommend users to add some additives according to the needs of the product, such as adding some additives to the color masterbatch, such as brightener, etc. This paper analyzes the indicators that should be paid special attention to when selecting the tensile machine for testing soft packaging materials. Of course, this will increase the cost of products

How about the heat resistance of Color Masterbatch

the heat-resistant grade of the special color masterbatch is generally compatible with the plastic used for products, and it can be safely used under normal temperature. Only under the following conditions will it cause varying degrees of color change, one is that the temperature exceeds the normal range, the other is that the shutdown time is too long

what is the difference between granulation coloring and masterbatch coloring

masterbatch coloring has the following advantages compared with granulation coloring:

1 Coloring and product processing are completed at one time to avoid the heating process of plastic caused by granulation coloring, which is good for protecting the quality of plastic products

2. To simplify the production process of plastic products

3. It can save a lot of electric energy

will the products colored with color masterbatch fade when the annual capacity of non caustic soda is 8million tons (the excess rate is 27%)

there is no absolutely fadeless product, and the products colored with color masterbatch may still fade, but for different grades of products, the degree is different, some are obvious, and some are difficult to detect
