Solutions · Polyethylene Storage
Polyethylene production and compounding call for large storage volumes and consistent product quality. PW Silo Systems designs aluminum and stainless steel storage, blending, and process silos for HDPE, LDPE, and PE pellets and powders – sized for your throughput.
Polyethylene Storage at a Glance
A polyethylene silo stores PE pellets or powder between production, compounding, and processing. Pellets must keep their quality and functionality until they are processed – the silo protects them from contamination and feeds them reliably to the next step.
PE plants handle large volumes, several grades, and powders with explosion risk. PW Silo Systems combines storage silos, seal-welded panel silos for large capacities, blending and homogenizing silos, and process silos into one system that fits your production layout.
Why Polyethylene Is Demanding
Volume, consistency, and safety decide how a PE silo system is built.
Polymer production and compounding need large storage capacities – often more than a road-transportable silo can hold.
Production lots differ, and a silo filled in batches forms layers of different quality.
In coated carbon steel silos, flaking paint and rust particles can end up in the pellets.
Fine PE powder is combustible. Filling and conveying release dust into the silo and its surroundings.
Some processes require pellets to be degassed, deodorized, or dried before further processing.
HDPE, LDPE, and specialty grades must not be mixed by accident.
Silo Materials
We build silos exclusively in aluminum and stainless steel. Both materials offer high corrosion resistance and a long service life – without a coating as the only protection against corrosion.
Which of our two materials fits your polyethylene silo depends on your product, your process, and your site. We review it with you.
Your Polyethylene Silo System
Storage silos, panel silos, blending silos, process silos, filtration, and safety equipment are engineered as one system. That means fewer interfaces for your team.
Storage
Concentric mass-flow discharge without asymmetric flow zones – as standard, site-assembled, indoor, or multi-compartment silos.

FAQ
Answers to the questions plant managers, engineers, and buyers ask most often about storing polyethylene in silos.
These PE products are on our list of bulk materials tested in our lab:
LLDPE, UHMWPE, metallocene PE, and PE wax we review with you based on your material data.
Seal-welded PW PanelLine silos reach capacities of up to 53,000 ft³. Their prefabricated components travel in standard containers or on curtain-side trucks – no oversize transport permits – and are assembled on site.
PW BlendLine silos blend and homogenize polymer pellets – with PW PipeBlend or PW CentralPipeBlend, depending on your product and throughput.
PW ProcessLine process silos are designed for deodorizing, degassing, and drying. We review your process requirements with you.
Fine PE powder is combustible. For combustible bulk solids we supply explosion-protected silos designed in accordance with applicable codes and regulations. Venting devices – rupture discs or explosion vents – are selected for your silo, your product, and your application.
Both are possible. Which material fits your polyethylene silo depends on your product, your process, and your site. We review the options with you.
Yes. We deliver to every U.S. state and support your project with silo transport, field assembly, silo installation and supervision, and site relocation of existing systems.
Very likely. Our silo systems are designed for nearly all free-flowing, granular, and powdered bulk solids. Send us your material details – kernel size, moisture, and how the product is filled and discharged – and we will review the right storage solution with you.
Tell us about your PE grades, required storage capacity, how the silo is filled and discharged, and your site conditions. Based on this, we work out the material, silo type, and configuration with you and send you a detailed quote.
