PE and PVC Non-Pressure Pipes
High-Performance Resins for Durable Non-Pressure Pipe Systems
Dow provides advanced polyethylene resins for the manufacturing of non-pressure pipes, delivering a modern solution for drainage, stormwater, and sewer systems. Unlike traditional materials like concrete and metal, pipes made from our PVC and PE resins offer exceptional resistance to corrosion, abrasion, and chemicals, supporting a service life of 100 years or more. Lightweight and easy to install, these solutions can help reduce total project costs while providing the robust, leak-free performance needed to build resilient and sustainable water management infrastructure.
PE non-pressure pipes enhance manufacturing and longevity
PE non-pressure pipes are designed for applications where no internal pressure is applied, such as drainage, irrigation, and conduit systems. They offer excellent processability, durability, and resistance to environmental factors, making them suitable for a variety of uses. These pipes are often employed in gravity flow systems and are valued for their ease of installation, longevity, and ability to handle diverse environmental conditions.

Plastics Additives offer improved processability, durability and circularity of PVC used in non-pressure pipes.
Unplasticized PVC (PVC-U) is durable and long-lasting material, where post-consumer recycling of pipes offers potential for multiple service lives for the PVC. Improved processability and impact resistance is offered through formulation with acrylic processing aids and both MBS and acrylic impact modifiers. Due to their light weight and crush resistance PVC non-pressure pipes find application in drainage, sewage, vents and fittings, as well as electrical conduit.

PVC pipes deliver exceptional service life—often up to 100 years—thanks to their corrosion resistance and toughness enhanced by PARALOID™ Impact Modifiers.
Through corrugated or foam-core designs and SURECEL™ Processing Aids, PVC achieves a superior strength-to-weight ratio, reducing material use and transportation impact while maintaining structural integrity.
PARALOID™ Impact and Process Aids boost impact and crush resistance while improving melt flow, manufacturing efficiency, and product consistency—ideal for high-speed or complex processing applications.
Featured Applications
Foam core wastewater drainpipes
PARALOID™ Acrylic Impact Modifiers, improve impact resistance and durability of pipes and fittings, even under high UV exposure faced by PVC-U gutters and downpipes.
PARALOID™ Acrylic Processing Aids facilitate the homogeneity needed for uniform wall thickness and high surface quality in PVC formulations for rainwater drainage pipes.
SURECEL™ Processing Aids are particularly suited to the processing needs of lower density and fine cell structure foam core pipe.
Corrugated pipes for land drainage
Drainage systems are essential for healthy crops. PARALOID™ Acrylic Processing Aids better melt strength and homogeneity for corrugation of PVC-U, whilst PARALOID™ Acrylic Impact Modifiers contribute to ductility, a property, essential during drainage slot cutting, as well as improving impact resistance and toughness needed during installation and service.
Sewer and wastewater pipes and fittings
Efficient wastewater treatment, is a priority. PARALOID™ and SURECEL™ Processing Aids improve melt properties and facilitate the cell structure of foamed PVC used in wastewater and sewer pipes. Foamed pipes offer possibilities for more sustainable plumbing through lower transport weight and reduced raw material quantities. The foam structure also offers noise dampening in buildings.
Our additives are used in foam core pipes, twin-wall, and corrugated PVC-U Pipes, for improved melt homogeneity for enhanced corrugation, and supporting better impact resistance and durability.
Corrugated PVC Conduit for wire and cables
Corrugated PVC conduit supports protection of wire and cables installed in buildings and must be flexible and tough. PARALOID™ Processing Aids are important for inducing the needed melt homogeneity and strength to allow extrusion and corrugation. An additional benefit of using these processing aids is the resultant enhanced surface finish.
Injection molding of fittings, valves, and vents
Whether push fit, screw on or cement assembly fittings or vents, PARALOID™ Processing Aids offer benefits in all PVC formulations in terms of better melt homogeneity leading to high weld line quality and defect free injection molding.
