Chlorinated polyethylene and polyethylene are common plastic materials, which are widely used in industrial production and daily life. Although they have similar names, they actually have significant differences in chemical structure and properties.

From the chemical structure, chlorinated polyethylene is formed by introducing chlorine atoms into polyethylene molecules. The introduction of chlorine atoms changes the bonding structure of polyethylene molecules, so that chlorine atoms are intermittently present in the molecular chain of chlorinated polyethylene. Polyethylene, on the other hand, is formed by the polymerization of ethylene molecules, with only carbon-carbon bonds in the molecular chain. This difference leads to a significant difference in performance between chlorinated polyethylene and polyethylene.

chlorinated polyethylene has high chemical resistance and weather resistance due to the influence of chlorine atoms on the molecular chain. In some special industrial fields, such as chemical industry and food processing, chlorinated polyethylene is widely used. Polyethylene has good flexibility and toughness because of its pure carbon-carbon bond structure, and has a wide range of applications in packaging, construction and other fields.

In addition, chlorinated polyethylene and polyethylene are also different in processing and molding. Due to the influence of chlorine atoms on the molecular chain of chlorinated polyethylene, its processing temperature range is narrow, the melting point is higher, and it needs a higher processing temperature to be able to shape. Polyethylene, on the other hand, is relatively easier to process and is therefore more common in processes such as granulation and injection molding.

To sum up, chlorinated polyethylene and polyethylene have their own characteristics in chemical structure and performance. From molecular structure to physical properties, they all have very different performances. In practical applications, we need to choose materials according to specific needs to ensure that the performance of the product reaches the best state.
