According to the various uses of plastic PE pipes, it is required to have both mechanical strength, heat resistance, cold resistance, transparency and other properties, and it is necessary to constantly have the emergence of new plastic pipes to replace traditional plastic pipes. PE pipe gradually from heavy to light, single function to multi-function development, co-extruded composite plastic three-layer PE pipe has become a new type of pipe. Because the various properties and functions of the co-extruded pipe can be designed according to needs, by selecting the appropriate matrix and reinforcement as well as the appropriate composition ratio and arrangement distribution, give full play to the performance advantages of the component materials, so as to obtain the comprehensive properties difficult to achieve by single materials such as metals, polymers, ceramics, such as high specific strength, high specific modulus, corrosion resistance, high temperature resistance and superconductivity, etc. Therefore, it has gradually become the development trend of plastic PE pipes in the future.
co-extrusion
1. Better product performance: Double-layer co-extrusion technology can extrude two different materials and compound them together, making full use of the advantages of two different materials to improve product performance.
2. The production process is simpler: compared with the traditional single-layer extrusion technical process, the double-layer co-extrusion technology production process is simpler and more energy saving.
4. Save resources: Double-layer co-extrusion technology can simplify the storage and processing of different kinds of materials, and reduce the waste of raw materials.
All in all, double-layer co-extrusion technology has become a core technology of modern plastic manufacturing and is widely used in all walks of life. With the continuous progress of science and technology, it is believed that double-layer co-extrusion technology will have a broader space for development
