A polyurethane screen panel (also called a polyurethane screen deck or PU screen mesh) is a screening media made from cast polyurethane elastomer. It features precisely molded square, round, or slotted openings and is used on vibrating screens to separate materials by size. Unlike woven wire mesh or rubber screens, polyurethane offers exceptional wear resistance, flexibility, and noise reduction.
"Tough, flexible, and long-lasting – polyurethane screens outperform wire and rubber."
Advantages of Polyurethane Screen Mesh
High wear resistance
The polyurethane surface supplies an outstanding wear and impact resistance performance. The polyurethane screen mesh can maintain a good condition during the frequent usage, in addition, it can also ensure the durability and long service life of screen mesh.
Smooth surface
The polyurethane screen mesh has a smooth surface compared to woven vibrating screens. The smooth surface can reduce pegging and blinding. Additional, the various aperture types can fit different materials, so it can improve the screening and separating efficiency.
Flexible
Flexible is the most outstanding feature of polyurethane screen mesh. It has various connection types, which can supply easy and fast installation and fixation. The interlocking system of polyurethane trommel screen is superior to the bolting connection type. Besides, the interlocking system make the replacement of worn screens be fast and need no efforts.
Various application
The polyurethane screen mesh has various aperture sizes and types, which can be used for different sizes of materials as well as wet or dry materials. In addition, the polyurethane screen mesh has various connection types which can be installed onto various vibrating screens, crushers and trommels.

Why Choose Us
Unmatched Size & Specification Range
– "If you can imagine it, we can mold it. No limits on diameter. No limits on length."
Most polyurethane suppliers offer standard sizes only. If you need something bigger or longer – they say no.
We say yes.
We design and build custom molds for parts of any size. Diameter? Unlimited. Length? Unlimited. Shape? Any geometry you need.
One-Stop Manufacturing - From Raw Marterial to Finished Product
– "We control everything from raw material to finished part. That means better quality and lower prices – no middlemen, no markup."
Most polyurethane suppliers are just resellers – they buy sheets or components from factories, add a markup, and sell to you.
We are a true manufacturer. We start with liquid polyurethane chemicals and produce everything in-house – from raw material formulation to final casting, cutting, and machining.
Wear Polyurethane Expert
– "We don't make everything in polyurethane. We focus on what we do best: wear-resistant elastomers. For decades."
Many polyurethane suppliers are generalists – they make gaskets, wheels, seals, bumpers, and anything else customers ask for.
We are specialists.
For over 20 years, we have focused exclusively on wear-resistant polyurethane elastomers – the toughest, most durable formulations for mining, aggregate, and heavy industrial applications.
In-House Lab Testing - Traceable Quality from Raw Material to Finished Part
– "We test every batch. We keep every record. And we can prove it – because we're the raw material manufacturer."
Most polyurethane suppliers cannot perform physical property testing. They buy finished sheets or parts from manufacturers and have no visibility into what's inside. They can't test. They can't trace. They can't guarantee.
We can.
Because we start with raw liquid chemicals and manufacture everything in-house. And we have our own fully equipped testing laboratory.
