Pipe & Corrugated Extrusion with Marlex® Polyethylene

Performance Pipe - cropped

Pipe and corrugated extrusion is a manufacturing process used to produce durable plastic piping systems for infrastructure, industrial and utility applications. Plastic pipe is used throughout North American industry due to its outstanding chemical resistance, long service life, ease of installation and cost effectiveness. 

CPChem has supplied polyethylene resins for pipe extrusion applications for more than 30 years. Our HDPE and MDPE pipe grades support both pressure and non-pressure systems, from small-diameter tubing to pipe exceeding eight feet in diameter.
