Product Description
Chlorinated polyethylene is a polymer material made from high-density polyethylene (HDPE) through chlorination substitution reaction. According to different structures and uses, chlorinated polyethylene can be divided into two categories: resin-type chlorinated polyethylene (CPE) and elastomer-type chlorinated polyethylene (CM). In addition to being used alone, thermoplastic resins can also be blended with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS and other resins and even polyurethane (PU). In the rubber industry, CPE can be used as a high-performance, high-quality special rubber, and can also be blended with other rubbers such as ethylene-propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM), etc.

2. CPE has average oil resistance, among which the resistance to ASTM No. 1 oil and ASTM No. 2 oil is excellent, which is equivalent to NBR; the resistance to ASTM No. 3 oil is excellent, better than CR, and equivalent to CSM.
3. CPE contains chlorine, has excellent flame retardant properties, and has burning and dripping properties. It can be matched with antimony flame retardants, chlorinated paraffin, and Al(OH)3 in appropriate proportions to obtain flame retardant materials with excellent flame retardant properties and low cost.
4. CPE is non-toxic, does not contain heavy metals and PAHs, and fully meets environmental protection requirements.
5. CPE has high filling performance and can be made into products that meet various performance requirements. CPE has good processing performance, and a variety of grades are available with Mooney viscosity between 50-100.

Coatings and anti-corrosion materials: CPE is used to produce chemical corrosion-resistant coatings and waterproof materials due to its excellent chemical corrosion resistance, especially suitable for industrial and marine environments.
Physical properties of CPE
The physical properties of CPE vary depending on its chlorine content and production process. The following are some of the main physical properties of CPE:
Heat resistance and cold resistance: CPE has high thermal stability and excellent cold resistance, and can maintain good physical properties in the temperature range of -30ºC to 120ºC.
Oil resistance and chemical resistance: CPE has good tolerance to most chemicals such as acids, alkalis, salts, and oils, especially its corrosion resistance to mineral oils and fuels.
Mechanical properties: CPE has good tensile strength and tear strength, good flexibility, and can still maintain a certain elasticity and impact resistance at low temperatures.
Aging resistance: Due to the introduction of chlorine atoms in the molecular structure of CPE, it has good oxidation resistance, ozone resistance and UV resistance, thereby extending its service life.
Chemical properties of CPE
The chemical properties of CPE are also closely related to its molecular structure:
Molecular structure: CPE is a modified material formed by introducing chlorine atoms into polyethylene through chlorination reaction. The chlorine atoms are randomly distributed on the polyethylene main chain, giving it unique physical and chemical properties.
Solubility: CPE is insoluble in most organic solvents, but it is soluble in some highly polar solvents such as chloroform and dichloromethane, and the solubility increases with the increase of chlorine content.
Chemical reactivity: The chlorine atoms of CPE can participate in chemical reactions under certain conditions, such as addition reactions with double bonds in rubber, improving the bonding properties and crosslinking degree of rubber.
Production methods of CPE
The production of CPE mainly includes suspension method, solution method and gas phase method. The following is a detailed introduction to the three main production methods:
Suspension method: The suspension method is to suspend polyethylene in water and carry out chlorination reaction by introducing chlorine gas into the reaction system. The advantages of this method are uniform chlorination reaction, easy control of chlorine content and stable product performance.
Solution method: The solution method is to dissolve polyethylene in a highly polar solvent and then introduce chlorine gas for chlorination reaction. The chlorine content of CPE produced by the solution method is evenly distributed, but this method requires the treatment of a large amount of solvent and has a high production cost.
Gas phase method: The gas phase method is to react polyethylene particles with chlorine at high temperature. This method has the advantages of high production efficiency and low energy consumption, but due to the violent chlorination reaction, it is easy to cause uneven product performance and requires strict control of reaction conditions.
Market prospects of CPE
With the continuous development of industry and construction, the demand for CPE is also increasing. Especially in the fields of wires and cables, automobiles and construction, the excellent performance of CPE makes it an indispensable material. In the future, with the continuous improvement of production processes and the continuous expansion of application fields, the market prospects of CPE will be broader.
Conclusion
As an important thermoplastic resin, chlorinated polyethylene (CPE) has been widely used in many fields due to its excellent physical and chemical properties. Through a variety of production processes such as suspension method, solution method and gas phase method, the performance of CPE can meet the needs of different applications. In the future, with the advancement of technology and the increase in market demand, CPE will play an important role in more fields.
