Building & infrastructure
HDPE for heating and plumbing pipe, drainage pipe, conduit and cable jacketing, and polypropylene for extruded panels and profiles. Grades are chosen by long-term strength, stress-cracking resistance and the product standard.
Polyolefins for pipe and cable are bought for decades of service. A heating pipe holds pressure at temperature, a drainage pipe carries the soil above it, and a cable jacket protects the conductor, mostly out of sight. This page covers HDPE for hot and cold water pipe, corrugated drainage pipe, conduit and cable jacketing, and polypropylene for extruded panels and profiles. Grade choice turns on long-term strength, resistance to stress cracking and the product standard the finished part is certified to.
What drives grade choice in building and infrastructure
For pressure pipe, long-term hydrostatic strength comes first. Data sheets show it as a minimum required strength (MRS) classification under ISO 12162 or, for hot water, as PE-RT Type I or Type II. For non-pressure pipe and conduit, stiffness and stress-cracking resistance matter more than a pressure rating. Cable jacketing adds thermal stability and electrical insulation.
HDPE covers all of these. The differences lie in molecular-weight distribution, density and stabilisation. The pipe and cable page explains how to read the data sheets. Its range is focused today and grows as our producer range widens.
Panels and profiles
Extruded panels, boards and profiles in polypropylene mostly use impact copolymers. They keep their stiffness, take knocks on a cold site, resist creep under a steady load and stay dimensionally stable after extrusion. Look for grades documented for sheet and profile extrusion. Corrugated and hollow board is covered on sheet and thermoforming. Send us the profile drawing, wall thickness and load case and we will suggest grades.
Standards and approvals
The finished pipe, conduit or cable is certified to its product standard; resin documentation does not replace that. Common product standards are ISO 22391 for PE-RT hot and cold water systems, EN 13476 for structured-wall drainage and sewer pipe, and EN 61386 for conduit. Pipe for drinking water also needs approval for water contact: the European positive lists under Directive (EU) 2020/2184 apply from 31 December 2026, with a transition to 31 December 2032 for products holding a valid national certificate on that date. We pass on the producer's data sheet, safety data sheet and regulatory summary for your file. Geotextiles are covered under Fibres & Nonwovens.
Send us the pipe, cable or profile, its dimensions and the standard you certify to.
Applications
Start from the part you make. Each page explains what the part asks of the polymer and lists the grades that fit.
