What Is The Difference Between White PE Pipe and Black PE Pipe?
Generally, the raw materials used in white PE pipes and black PE pipes on the market are polyethylene particles.

The main difference between white PE (Polyethylene) pipe and black PE pipe lies in their intended applications and the additives used in their manufacturing process.
- Color: As the names suggest, the primary difference is the color. White PE pipes are typically used for potable water systems, while black PE pipes are commonly used for non-potable water systems and industrial applications.
- Additives: The color difference is often due to the additives incorporated into the PE resin during the manufacturing process. Black PE pipes usually contain carbon black additives, which provide UV resistance and protect the pipe from degradation caused by sunlight exposure. White PE pipes, on the other hand, may contain different additives to meet specific requirements for potable water applications, such as antioxidants and stabilizers to ensure the water’s quality remains unaffected.
- Applications: Black PE pipes are commonly used for irrigation, wastewater, drainage, and industrial piping systems where UV resistance is crucial. They are not typically approved for use in potable water systems due to concerns about the potential leaching of additives. White PE pipes are specifically designed and approved for potable water distribution systems, ensuring that the water remains safe for human consumption.
- Regulatory Compliance: White PE pipes intended for potable water applications are manufactured to meet specific regulatory standards and certifications, ensuring they are safe for use in contact with drinking water. These standards may include NSF/ANSI 61 certification in the United States or similar certifications in other regions. Black PE pipes may have different regulatory requirements depending on their intended applications.
In summary, while both white and black PE pipes are made from the same material, their differences lie in their intended applications, additives used in their manufacturing, and regulatory approvals. It’s essential to select the appropriate type of PE pipe based on the specific requirements and regulations governing the intended use case.
White PE pipes are produced with pure materials by adding white masterbatch or without color masterbatch during the production process; while black PE pipes are produced with a certain amount of color masterbatch added during the production process;
PE pipes are generally used outdoors, and sunlight will have a certain impact on the service life of the pipes. Whether it is a white PE pipe with color masterbatch or a PE pipe without white color masterbatch, they all have one characteristic: they are not UV-resistant, while black PE pipes can effectively protect against UV rays, are not prone to moss, and can effectively extend the life of the pipe. Pipe life;
Black PE pipes, due to the addition of black color masterbatch, can also easily add some recycled waste. For drinking water pipes, this is not allowed in the national standards, while white PE pipes, especially white PE pipes produced from line raw materials It is easy for consumers to see the quality of materials, and it is easier for consumers to rest assured.
