注塑级黑色母粒是一种专门用于注塑加工的添加剂，其作用是将塑料原料中的色素、光稳定剂等添加进去，从而达到改变塑料颜色、提高其耐光性等效果的目的。下
一、注塑级黑色母粒的种类
注塑级黑色母粒通常有两种，一种是高浓度母粒，另一种是低浓度母粒。高浓度母粒中添加的色素浓度较高，通常在40%左右；而低浓度母粒中添加的色素浓度较低，只有15-20%左右。不同浓度的母粒适用于不同的加工要求，用户可以根据自己的实际需求来选用。
二、注塑级黑色母粒的作用
1、提高塑料材料的颜色
注塑级黑色母粒的主要作用就是提高塑料材料的黑色程度，使其在外观上更加饱满，美观。这对于那些对外观要求比较高的产品来说尤其重要，比如家具、汽车、电器等。
2、增强塑料材料的耐光性
注塑级黑色母粒中有一些光稳定剂，其作用就是提高塑料材料的耐光性，防止其受到紫外线等外界因素的影响而失去原有的性能，延长使用寿命。
3、改善塑料原材料的性能
除了改变塑料的颜色和增强耐光性之外，注塑级黑色母粒还可以在一定程度上改善塑料原材料的的性能，比如增加它的强度、硬度等。
三、应用范围
注塑级黑色母粒的应用范围非常广泛，几乎所有需要改变塑料颜色、提高耐光性或改善塑料性能的行业都会使用到它，比如家具、电器、汽车、电子等。
四、选购方法
1、关注母粒的质量
注塑级黑色母粒的质量是非常关键的，如果选错了质量不够好的母粒，就会导致加工后的产品在外观、性能等方面都不能满足要求。因此选择时需要重视母粒的质量，尽可能选择一些知名品牌的产品。
2、看浓度
不同浓度的注塑级黑色母粒适用于不同的加工类型，用户需要根据自己的实际需求来选择对应的浓度。
3、关注成分
购买注塑级黑色母粒时，需要仔细查看成分表，确定是否包含有害物质，以免影响产品质量和安全。
Injection grade black masterbatch is a kind of additive specially used in injection molding processing, its role is to add pigments and light stabilizers in plastic raw materials, so as to achieve the purpose of changing the color of the plastic, improve its light resistance and other effects. Next
I. Types of black masterbatches for injection molding
There are usually two kinds of black masterbatches for injection molding, one is high concentration masterbatches and the other is low concentration masterbatches. The concentration of pigment added in the high concentration masterbatch is higher, usually around 40%; while the concentration of pigment added in the low concentration masterbatch is lower, only around 15-20%. Different concentrations of masterbatches are suitable for different processing requirements, users can choose according to their actual needs.
Black masterbatch for injection molding
Second, the role of injection molding grade black masterbatch
1、Improve the color of plastic materials
The main role of injection black masterbatch is to improve the black degree of plastic materials, so that it is more full in appearance, beautiful. This is especially important for those products with high requirements for appearance, such as furniture, automobiles, electrical appliances and so on.
2, enhance the light resistance of plastic materials
Injection black masterbatch has some light stabilizers, its role is to improve the light resistance of plastic materials, to prevent it from being affected by ultraviolet light and other external factors and lose the original performance, to extend the service life.
3、Improve the performance of plastic raw materials
In addition to changing the color of plastic and enhance light resistance, injection black masterbatches can also improve the performance of plastic raw materials to a certain extent, such as increasing its strength, hardness and so on.
Application Scope
The application range of black masterbatch is very wide, almost all the industries that need to change the color of plastics, increase light resistance or improve the performance of plastics will use it, such as furniture, electrical appliances, automobiles, electronics and so on.
Fourth, the purchase method
1、Focus on the quality of the masterbatch
The quality of injection molding grade black masterbatch is very critical, if you choose the wrong quality masterbatch is not good enough, it will lead to the processed products in terms of appearance, performance and other aspects can not meet the requirements. Therefore, you need to pay attention to the quality of the masterbatch when choosing, as far as possible, choose some well-known brands of products.
2, look at the concentration
Different concentrations of injection molding grade black masterbatches are suitable for different types of processing, users need to choose the corresponding concentration according to their actual needs.
3、Attention to the composition
When buying injection molding grade black masterbatches, you need to carefully check the composition table to determine whether it contains harmful substances, so as not to affect product quality and safety.
