Applications:
MPP non-excavation power pipe granular foaming agent is a professional modified additive designed specifically for MPP (modified polypropylene) non-excavation power pipeline production. Adopting granular form, it features excellent fluidity and uniform dispersion in MPP resin, avoiding dust pollution and uneven mixing during production, ensuring stable extrusion and continuous processing efficiency.
This foaming agent has a suitable decomposition temperature matching MPP processing conditions, releasing gas gently and uniformly to form compact, closed-cell microstructures inside the pipe. Such a structure effectively reduces overall material density and achieves obvious lightweight effect, making transportation, handling and non-excavation laying easier while lowering raw material consumption and production costs.
A core advantage is its remarkable improvement in ring stiffness of MPP power pipes. The uniform cell distribution strengthens the pipe's internal support structure, enhancing compression resistance, creep resistance and external load bearing capacity. Even under long-term buried pressure and geological deformation, the pipeline maintains structural integrity without cracking or collapsing, meeting strict engineering standards for non-excavation laying.
In addition, it helps improve surface flatness and dimensional stability, eliminating defects such as bubbles, pits and warping. The foamed pipe maintains good insulation performance and chemical corrosion resistance, adapting to complex underground environments. This product is low odor, environmentally friendly and safe for operators.
With strong process adaptability, it is widely used in various MPP non-excavation power pipe extrusion lines. By balancing high ring stiffness and lightweight performance, it effectively upgrades product quality and extends service life, making it an essential additive for high-performance MPP power pipeline manufacturing.
Suitable for MPP power pipes, PE municipal pipes, and products requiring multi-layer co-extrusion.
