What are the raw materials for plastic particles

1、 Raw materials for plastic particles

The raw materials for plastic particles mainly come from fossil fuels such as oil and natural gas. These raw materials are first refined and processed to obtain a mixture called petrochemical products. Then, this mixture is fed into a furnace for pyrolysis and cracking reactions, breaking down into various hydrocarbon compounds.

These hydrocarbon compounds undergo further processing, such as polymerization, condensation, esterification, etc., to ultimately obtain polymer particles. The raw materials and production processes used for different types of plastic particles may also vary.

2、 Manufacturing process of plastic particles

The manufacturing process of plastic particles generally includes the following steps:

a. Raw material extraction and processing: Fossil fuels such as oil and natural gas are processed to obtain petrochemical products.
b. Pyrolysis reaction: Petrochemical products are sent into a furnace for high-temperature decomposition reaction, which decomposes into hydrocarbon compounds.

c. Polymerization reaction: Polymerization, condensation, esterification, and other reactions of hydrocarbon compounds are carried out to obtain polymer particles.

d. Processing and molding: Polymer particles are fed into injection molding machines, extruders, and other equipment for processing and molding, ultimately manufacturing various plastic products.

3、 Market Application of Plastic Particles

Plastic particles are widely used in various fields, such as building materials, electronics, automobiles, toys, tools, and other manufacturing industries. Different types of plastic particles have different properties and characteristics, which can meet the manufacturing needs of various products.

In addition, with the continuous improvement of people's environmental awareness, recycling and reusing waste plastic particles has also become an important direction. Recycled plastic particles can be reprocessed and reused to produce various recycled plastic products, greatly reducing environmental pollution.

Summary

Plastic particles are an important material, mainly derived from fossil fuels such as oil and natural gas, and obtained through a series of processing treatments. Its manufacturing process includes steps such as raw material extraction and processing, pyrolysis reaction, polymerization reaction, and processing molding. Different types of plastic particles have different properties and application scenarios. At the same time, recycling and reusing waste plastic particles is also an important development direction.
