Chlorinated polyethylene (CPE) is a macromolecule material created by substituting hydrogen atoms of concentrated polyethylene (HDPE) with chlorine atoms. CPE comprises a chlorine content ranging from 34 to 44 percent. Chlorinated polyethylene exists as a white powder that is non-toxic and tasteless.
Because of its soft, rubbery texture, chlorinated polyethylene can be mixed with polyvinyl chloride to improve its strength, weather resistance, chemical resistance, and ozone resistance. CPE also exhibits excellent oil resistance, coloring function, and flame retardancy.
Important Characteristics of CPE
- Chlorinated polyethylene is non-toxic and includes non-heavy metals, making it suitable for the environment.
- CPE has superb flame resistance properties and is also combustion-drip proof. Thus, fire-resistant materials can be created by mixing CPE with certain amounts of chlorinated paraffin, AI(OH)3, and antimony flame retardant.
- Chlorinated polyethylene is a saturated rubber with remarkable chemical properties, including acid and alkali resistance and thermal oxygen aging.
- CPE can be made according to specific application requirements and provides an excellent processing performance.
Chlorinated polyethylene Uses
Chlorinated polyethylene has several applications in a wide range of industries. The most basic applications include:
Construction applications
CPE can be used as an impact modifier in construction applications to improve the overall strength of the material. It enhances impact resistance and reduces the cost of rigid PVC. CPE is sometimes added to building materials, such as underground drainage, profiles, rainwater goods, and doors and windows.
Wiring and cables
When blended with other rubber materials, chlorinated polyethylene is primarily used to manufacture wires, cables, hydraulic hoses, and plastic sheets. It can sometimes be used to modify ABS, boards, and PVC profile pipes.
In addition, CPE endures harsh conditions within building walls, like dampness and exposure to changing temperatures, among other things. For that reason, CPE is the most reliable material used in wire and cable jacketing.
Improve Flame Retardant Function
CPE can be combined with polypropylene, ABS, and low-density polyethylene to enhance flame retardant function, printing function, polystyrene, polyurethane, and aging resistance of PVC plastics. It can also be used as top performance rubber, which can be blended and applied with butyl rubber, chlorosulfonated polyethylene, nitrile rubber, and ethylene propylene rubber.
Water Pipes
CPE aids in conserving water and energy by creating leak-free water pipes that resist environmental stress. Building materials that contain CPE are durable and have low breakage rates, which can help enhance functionality and energy efficiency.
CPE Blends
The great additive acceptability properties of CPE can benefit blends where economic and compound performance is required. CPE combines different types of plastics, including PVC, EVA, and polyethylene, which can be developed into final products with excellent dimensional stability.
