The difference between resin powder and molding powder

In the chemical industry, resin powder and molding powder are two commonly mentioned terms, but many people are not clear about the difference between them. These two materials have their own characteristics in industrial applications. Choosing the right material is very important for production efficiency and product quality. This article will analyze the differences between resin powder and molding powder in detail from multiple angles to help you better understand the characteristics of these two materials and their application scenarios.

1. basic concepts

1. Resin powder definition

Resin powder refers to a powdered product processed from resin raw materials. Resins are organic compounds, usually polymerized from a variety of monomers, with good processability and chemical stability. Resin powder is widely used in coatings, plastics, posites and other fields, and is the basic material of many materials.

2. Type into powder definition

Molding powder is a powdery material that has been processed by a special process and is usually used in a compression molding process. The particle shape, particle size and particle distribution of the forming powder are very important, which directly affect the quality of the product after molding.

2 The main differences

1. source and production process

1. Material source

The raw material of the resin powder can be a natural source or a synthetic resin. Natural resins, such as natural rubber and natural petroleum resins, have good flexibility and processability. Synthetic resin powder is mainly synthesized by chlorinated polyethylene, chlorinated propylene, etc.

2. Type into powder of raw materials

The raw material of molding powder is usually high-performance polymers, which is processed by special processes such as melt blowing and extrusion to make it suitable for compression molding.

2. uses

1. Resin powder application scenarios

Resin powder is widely used in coatings, plastics, posites, fillers and other fields because of its excellent processing performance. For example, unsaturated polyester resin powders commonly used in automobile manufacturing are used to produce high-performance coatings and plastics.

2. Type into powder application scenarios

The molding powder is mainly used in the molding process, such as the production of plastic parts, electronic components, daily necessities, etc. It is characterized by regular particle shape, easy to form, and high product strength.

3. performance index

1. Fluidity and viscosity

The fluidity of resin powder is usually high, suitable for a variety of processing methods. The molding powder has poor fluidity and high viscosity, which is more suitable for the compression molding process.

2. Particle size distribution

The resin powder has a wide particle size distribution and is suitable for a variety of applications. The particle size distribution of the molding powder is very critical, usually within a specific range to ensure stable quality after molding.

3. selection recommendations

When selecting materials, the choice should be made according to the specific process and application requirements. For example, if you need to produce plastic parts that require good processing performance, you can choose resin powder; if you need to produce products that require high-pressure molding, you can choose molding powder.

4. summary

There are significant differences between resin powder and molding powder in terms of source, use, and performance. Understanding these differences can help you make the right choices in industrial applications, thereby improving production efficiency and product quality. I hope this article can help you with your production decision.
