Chlorinated polyethylene and polyethylene are common plastic materials widely used in industrial production and daily life. Although they have similar names, they actually have significant differences in chemical structure and properties
From a chemical structure perspective, chlorinated polyethylene is formed by introducing chlorine atoms into polyethylene molecules. The introduction of chlorine atoms alters the bonding structure of polyethylene molecules, resulting in intermittent presence of chlorine atoms on the molecular chain of chlorinated polyethylene. Polyethylene, on the other hand, is formed by polymerization of ethylene molecules, with only carbon carbon bonds present on the molecular chains. This difference leads to significant differences in performance between chlorinated polyethylene and polyethylene
Chlorinated polyethylene has high chemical corrosion resistance and weather resistance due to the presence of chlorine atoms on its molecular chain. In some special industrial fields, such as chemical and food processing, chlorinated polyethylene is widely used. Polyethylene, on the other hand, has good flexibility and toughness due to its pure carbon carbon bond structure, and is widely used in packaging, construction, and other fields
In addition, chlorinated polyethylene and polyethylene also differ in processing and molding. Due to the influence of chlorine atoms on the molecular chain of chlorinated polyethylene, its processing temperature range is narrow and its melting point is high, requiring a higher processing temperature to shape. Polyethylene, on the other hand, is relatively easier to process, making it more common in processes such as granulation and injection molding
In summary, chlorinated polyethylene and polyethylene have their own characteristics in terms of chemical structure and properties. From molecular structure to physical properties, they all exhibit completely different behaviors. In practical applications, we need to select materials based on specific needs to ensure that the performance of the product reaches its optimal state.
