PU Polyurethane Material Overview

PU (polyurethane) is a high-performance engineering material widely used in applications requiring extreme wear resistance and impact strength.

Compared with UHMW PE, PU offers significantly higher abrasion resistance, making it ideal for heavy-duty and high-impact material handling environments.

Available Types

We supply two main types of PU polyurethane products:

Standard PU Sheet

  • Thickness: 4 – 30 mm
  • Suitable for general wear-resistant applications

PU with Steel Wire Mesh Reinforcement

  • Thickness: 6 – 30 mm (commonly ≤20 mm)
  • Improved structural strength and impact resistance
  • Extended service life under heavy load conditions

Key Features

  • Wear resistance up to 4 times higher than UHMW PE
  • High impact strength and elasticity
  • Good anti-static performance
  • Stable performance with low shrinkage
  • Wide adjustable hardness range
  • Reduced noise during operation

Technical Information

  • Density: approx. 1.27 g/cm³
  • Maximum working temperature: ≤75°C
  • Custom sizes and machining available

Applications in Material Handling Systems

PU polyurethane materials are widely used in:

  • Conveyor flights and wear parts
  • Chute and hopper liners
  • Grain slide tubes and transfer points
  • Buffer plates in ports and granaries
  • High-impact and heavy-wear areas

How to Choose PU Polyurethane Sheet

Size and Customization

The maximum PU sheet size is 5000 × 1260 mm, produced by combining two molds of 2500 × 1260 mm.

For sizes below 2120 × 1260 mm, sheets can be cut according to your requirements.

Available Types

We supply two main types of PU polyurethane materials:

  • Standard PU Sheet → General wear-resistant applications
  • PU Sheet with Steel Wire Mesh Reinforcement → Enhanced strength and impact resistance

Thickness Range

  • Standard PU sheet: 4 – 30 mm
  • Steel mesh reinforced PU sheet: 6 – 30 mm (commonly ≤20 mm)

Technical Properties

  • Density: approx. 1.27 g/cm³
  • Maximum working temperature: ≤75°C
  • Excellent wear resistance (up to 4× UHMW PE)
  • Good impact resistance and anti-static performance
  • Stable structure with low shrinkage

Why Choose PU Instead of UHMW PE?

Property PU Polyurethane UHMW PE
Wear Resistance Excellent (up to 4× higher) Very good
Impact Resistance Excellent Outstanding
Elasticity High Low
Best Application Heavy impact & high wear Low friction & flow improvement

When to Choose PU Polyurethane Instead of UHMW PE

  • When extremely high wear resistance is required
    → PU provides significantly higher abrasion resistance (up to 4× UHMW PE), making it ideal for heavy-duty wear conditions
  • When the application involves strong impact or heavy loads
    → PU has better elasticity and energy absorption, suitable for high-impact areas such as transfer points and buffer zones
  • When longer service life is needed in harsh environments
    → PU performs better in high-wear and high-stress applications, reducing maintenance frequency and replacement costs

If UHMW PE is wearing out too quickly in your application, PU polyurethane is often a more durable solution.

PU vs UHMW PE vs Nylon – Material Selection Guide

Property PU Polyurethane UHMW PE Nylon (PA / Oil Nylon)
Wear Resistance Excellent (up to 4× UHMW) Very good Good
Friction Medium Very low (best) Low
Impact Resistance Excellent Outstanding Good
Elasticity High Low Medium
Moisture Absorption Low Very low Higher
Noise Low Very low Low
Best Application High wear & heavy impact Low friction & smooth flow Mechanical parts & load-bearing
  • Choose PU → for extreme wear and high-impact conditions
  • Choose UHMW PE → for low friction and smooth material flow
  • Choose Nylon → for mechanical components like gears and bearings
