Classification method and grade of non-woven masterbatch

The color masterbatch of non-woven fabric is a kind of masterbatch made by adding color colorant to plastic as the base material. Color masterbatch is used in non-woven fabric. The classification methods of color masterbatches are commonly used as follows:


Classified by carrier: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc.


Classified by purpose: such as registered masterbatch, blow molding masterbatch, spinning masterbatch, etc.


Each species can be divided into different grades, such as:


1. Advanced injection masterbatch: used for cosmetic packaging, toys, electrical surgery and other advanced products.


2. Ordinary injection color masterbatch: used for general daily-use plastic products, industrial containers, etc.


3. Advanced blown film masterbatch: used for blow molding coloring of ultra-thin products.


4. Ordinary blown film masterbatch: used for blow molding and coloring of general packaging bags and woven bags.


5. Spinning masterbatch: used for spinning and coloring of textile fiber. The masterbatch has fine pigment particles, high concentration, strong coloring power, good heat resistance and light resistance.


6. Low-grade color masterbatch: used to manufacture low-grade products that do not require high color quality, such as trash cans, low-grade containers, etc.


7. Special masterbatch: It is a masterbatch manufactured by using the same plastic as the carrier according to the plastic species designated by the user for the product. For example, PP masterbatch and ABS masterbatch use PP and ABS as the carrier respectively. Universal color masterbatch: some resin (usually low melting point PE) is also used as a carrier, but it can be applied to coloring other resins besides the carrier resin.


8. General-purpose color masterbatch: The general-purpose color masterbatch is relatively simple and convenient, but it has many disadvantages. It is recommended that users choose special color masterbatch. The heat-resistant grade of the special masterbatch is generally compatible with the plastic of the product, and it can be used with confidence under normal temperature. Only under the following conditions will cause different degrees of discoloration, one is that the temperature exceeds the normal range, and the other is that the downtime is too long.


9. Compared with granulation coloring, masterbatch coloring has the following advantages:


(1) Coloring and product processing are completed at one time, avoiding the heating process of pelletizing and coloring on plastics, which is good for protecting the quality of plastic products;


(2) Minimize the production process of plastic products;


(3) It can save a lot of power.
