PE pipe is widely used in water supply and drainage, gas transportation and other fields, and its excellent performance cannot be separated from the synergy of various components. PE pipe is made of polyethylene resin as the main raw material, and heat stabilizer, coloring agent and processing aid are added at the same time. It is made by extrusion molding.

polyethylene resin is the foundation of PE pipe, which determines the basic physical and chemical properties of the pipe, endows the pipe with good flexibility, corrosion resistance and low temperature resistance, so that it can be used stably in different environments and ensure the normal operation of the conveying function.

heat stabilizer, also known as antioxidant, plays an important role in the production process of PE pipe. PE resin is prone to oxidation reaction when extruded at high temperature, resulting in the decline of pipe performance. Heat stabilizers can delay or inhibit this high-temperature oxidation process and prevent molecular chain breakage, thereby maintaining the strength and toughness of the pipe and prolonging its service life.

colorants, usually also have light stabilization function, and the common colors in PE pipe raw materials are black or blue. On the one hand, they can effectively absorb or reflect ultraviolet rays, prevent polyethylene from degrading due to light, and improve the weather resistance of the pipe; on the other hand, the specific color plays a warning role, reminding the construction staff to avoid accidental damage to the pipeline, and ensure the safety of construction and use.

processing aids are added to optimize the processing performance of polyethylene. It can reduce the melt viscosity of the resin, improve the fluidity, make the raw materials more uniform and stable in the extrusion process, improve the production efficiency, and ensure the molding quality of the pipe, ensure the uniform thickness of the pipe wall and the smooth surface. These ingredients complement each other to create a reliable PE pipe.
