Demand for conduit pipe is expected to surge globally due to rapid industrialization and urbanization in residential and commercial sectors. Just in the U.S., according to Market Research analysis, expected growth of the plastic conduit pipe market is at a CAGR of more than 5% over the next ten years. In response to this growth, a new high performance bimodal HDPE conduit pipe resin has been developed. This paper will cover the improved resin properties, including tensile strength, flexural modulus and ESCR, that meet or exceed the requirements of conduit pipe standards such as ASTM F2160, ASTM D3485 and UL 651A. Several commercial conduit pipe production runs have been conducted with this new resin at standard industry operating conditions for extruder and die temperature profiles, for sizes ranging from 1.25” to 4.0” IPS Schedule 40. These trials have shown excellent processability (lb./hr. and feet/min.) needed to maximize conduit pipe production rates, both with, and without, the incorporation of post-industrial recycle content.

In PPXX, a technology was presented for the first time that could bi-axially orient polyolefin pipes. With this technology, it is possible to prepare pipes that have a performance far beyond the standard ones. One approach to achieving this performance is via a continuous in-line process. To optimize the in-line...
