China PU Vibrating Screen Mesh Sieve Plates - High-Quality Suppliers & Factory with Excellent Wear Resistance
Polyurethane PU screen mesh sieve plates have various types and can be designed according to your requests. Polyurethane screens feature outstanding characteristics such as high temperature resistance, aging resistance, radiation resistance, and electrical insulation.
Characteristics
Polyurethane PU screen mesh sieve plates make full use of the excellent wear resistance of polyurethane, featuring high strength, high elongation, and high elasticity across a wide range of hardness. It offers good shock absorption performance, oil resistance, low temperature resistance, heat aging resistance, radiation resistance, and electrical insulation properties. Combined with a reasonable sieve and installation structure design, the polyurethane sieve plate delivers the following performance benefits:
- ✓ Good abrasion resistance & long service life: Its abrasion resistance is 3 to 5 times better than steel screen mesh and over 5 times than ordinary rubber screen mesh.
- ✓ Low maintenance workload: The polyurethane screen mesh is highly durable and not easily damaged, which greatly reduces the amount of maintenance and operational downtime.
- ✓ High cost-effectiveness: Although the initial cost of a polyurethane sieve plate is nearly 2 times higher than a stainless steel sieve under the same specification, its service life is 3 to 5 times longer, making the final cost highly economical.
- ✓ Excellent moisture resistance: It functions efficiently with water as the medium. In the presence of water or oil, the friction coefficient between the polyurethane and the material is reduced, improving screening efficiency, avoiding wet particle clogging, and extending service life.
- ✓ Environmental resistance: It is corrosion-resistant, non-flammable, non-toxic, and tasteless.
- ✓ Anti-blocking design: Due to the reasonable design of the sieve holes and its unique manufacturing process, extreme-sized particles will not block the sieve openings.
- ✓ Vibration & noise reduction: Excellent vibration-absorbing performance and strong silencing ability reduce noise, preventing the screen material from breaking during the vibration process.
- ✓ Self-cleaning effect: The secondary vibration characteristics of polyurethane give the sieve plate a self-cleaning effect, ensuring consistently high screening efficiency.

Frequently Asked Questions
How does the service life of a polyurethane screen mesh compare to steel?
The abrasion resistance of polyurethane screen mesh is 3 to 5 times better than steel screen mesh and more than 5 times longer than ordinary rubber screen mesh, ensuring a significantly longer service life.
Is polyurethane screen mesh cost-effective despite its higher initial price?
Yes. While the initial cost of a polyurethane sieve plate is about 2 times higher than a stainless steel sieve, its service life is 3 to 5 times longer. This drastically reduces maintenance and replacement costs, making it highly economical.
How does moisture affect the performance of PU screen mesh?
Water acts as a lubricant on polyurethane. When screening materials with water or oil, the friction coefficient drops, which facilitates screen penetration, improves efficiency, prevents clogging of wet particles, and reduces wear.
Does the polyurethane screen mesh get easily blocked?
No. Thanks to the reasonable design of the sieve holes, its unique manufacturing process, and the secondary vibration (self-cleaning effect) of the polyurethane material, particles of extreme sizes will not block the sieve holes.
Can polyurethane screens help in reducing noise?
Yes, polyurethane has excellent vibration-absorbing performance and strong silencing ability. This significantly reduces operational noise and prevents the material from breaking during the vibration screening process.
