Masterbatch, as a plastic additive, has been widely used in the plastic industry. It can not only give plastic products rich colors, but also improve the performance of plastics and increase the added value of plastic products. This article will elaborate on the definition, classification, application, development trend and other aspects of masterbatch.

Definition and classification of masterbatch

1. Definition

Masterbatch, also known as pigment masterbatch or color masterbatch, is a granular product made by uniformly dispersing pigments, dyes, additives and other substances in plastic resin through a certain production process. Masterbatch has the characteristics of bright color, good dispersibility and excellent processing performance.

2. Classification

According to different classification standards, masterbatch can be divided into the following types:

(1) Classification by use: general masterbatch, functional masterbatch, special masterbatch.

(2) Classification by resin type: polyethylene (PE) masterbatch, polypropylene (PP) masterbatch, polyvinyl chloride (PVC) masterbatch, etc.

(3) Classification by colorant: pigment masterbatch, dye masterbatch.

Application of masterbatch

1. General masterbatch

General masterbatch is suitable for coloring various plastics, such as polyethylene, polypropylene, polyvinyl chloride, etc. It is widely used in daily necessities, building materials, packaging materials, toys and other fields.

2. Functional masterbatch

Functional masterbatch has special functions, such as anti-ultraviolet, anti-static, , flame retardant, etc. It is widely used in electronic products, automotive interiors, outdoor products and other fields.

3. Special masterbatch

Special masterbatch is developed for specific plastic products and has excellent matching performance. Such as injection molding masterbatch, blow molding masterbatch, hot melt adhesive masterbatch, etc.

Development trend of masterbatch

1. Green and environmental protection

With the continuous improvement of environmental awareness, green and environmentally friendly masterbatch will become a development trend. The new environmentally friendly masterbatch has the characteristics of low toxicity, harmlessness, and degradability, which is in line with national environmental protection policies.

2. High performance

In order to meet the high performance needs of plastic products, high-performance masterbatches will continue to be developed. Such as high strength, high wear resistance, high gloss, high thermal stability, etc.

3. Personalized customization

With the intensification of market competition, the personalized needs of plastic products are becoming increasingly prominent. The masterbatch industry will develop in the direction of personalization and customization to meet the needs of different customers.

4. Intelligent production

With the development of technologies such as artificial intelligence and the Internet of Things, masterbatch production will be intelligent. Through intelligent production, production efficiency can be improved and production costs can be reduced.

Masterbatches are increasingly widely used in plastic processing, and their development prospects are broad. Faced with the development trends of green environmental protection, high performance, personalized customization, and intelligent production, the masterbatch industry will continue to innovate and provide more products and services for the plastic products industry.
