As urban areas expand, the demand for infrastructure such as drainage, sewage, and communication pipelines has surged. HDPE double-wall corrugated pipes, known for their excellent compression resistance, corrosion protection, and sealing properties, have become the ideal choice for these systems. This growing need has driven the development of HDPE double-wall corrugated pipe masterbatch. With increasing environmental regulations, these pipes must be recyclable and easy to process, while also meeting strength requirements. Therefore, the masterbatch used must offer superior dispersion, coupling, and post-molding mechanical strength.
