Why is the blackness of the black masterbatch insufficient?

In recent years, black masterbatch has gradually become one of the indispensable raw materials in the plastic products industry. Whether it is a large supermarket or a small shop on the side of the road, plastic products have been seen everywhere, which also shows how strong the market demand for black masterbatch is. Most of the black masterbatch is used on black plastic products, which also gives the finished product a shiny appearance. However, there are still some products on the market that use black masterbatch in the production process but have not obtained the corresponding effect. What causes this problem?

 

The impact of recycled plastics

In the past, the production of masterbatch mostly relied on recycled plastics, which were collected, sorted, cleaned and reprocessed into new materials for further use. Most of the most popular thermoplastics cannot be quickly degraded, which is the biggest difference between them and biodegradable plastics. Therefore, recycling plastic and using it as a source of raw materials is essential in the environmental protection process. Therefore, many manufacturers also intend to use recycled materials in their plastic products in the future. However, the compatibility of recycled plastics is also a concern for many people. It is much worse than the new material. After investigation, the performance of black when using recycled plastics is quite different from the general results. After testing, the performance of general black masterbatch is more likely to deviate from the performance of recycled materials, so it is more likely that the blackness is not black enough. It is recommended that customers choose the corresponding black masterbatch according to the performance of the raw material.

 

Influence of plastic type

Different market demands make black masterbatches have different characteristics, and manufacturers are also specialized in producing black masterbatches that can be used in different scenarios. Currently, PP black masterbatch and PE black masterbatch are the most common. But it is undeniable that there are so many types of masterbatch in time, and the type of raw plastic in the production process may not necessarily match the black masterbatch. Under such limitations, the black masterbatch may not be able to achieve the desired final effect, resulting in problems such as diffusion and insufficient blackness. Therefore, we recommend that customers use modified special black masterbatch.

 

Focus on the external appearance of the masterbatch

The products that masterbatch suppliers can provide are different, but many customers often only pay attention to the appearance and color of the black masterbatch itself when choosing a supplier. In fact, the plasticity and compatibility of the black masterbatch are the most important factors to consider. This is why they made a big mistake when they ordered a large amount of black masterbatch for their entire product from a new manufacturer. After many customers order inappropriate black masterbatches, they will produce and mix them in the original proportions, which will eventually lead to many quality problems.
