Metal forming is a demanding and important process, as its current market size in 2025 sits at around $205 billion. Therefore, it needs materials that can withstand significant stress while delivering reliable results. Polyurethane die pads have emerged as an industry-leading solution, surpassing traditional rubber in numerous aspects. With their exceptional resilience, customizability, and superior mechanical properties, polyurethane pads offer unparalleled advantages for high-pressure metal forming applications.
Here, we’ll explore why polyurethane is the material of choice for die pads, diving into its unique properties, advantages, and its wide range of industrial applications. Whether you’re seeking greater strength, enhanced abrasion resistance, or tailored durometers for specific use cases, polyurethane die pads deliver unmatched value in metal forming.
Rubber vs. Polyurethane: A Comparison
Rubber vs urethane are both popular materials for die pads, but their characteristics vary significantly. Rubber is valued for its flexibility and cost-effectiveness, making it suitable for applications where affordability is a priority. However, it tends to wear out faster and is less durable under repeated stress or heavy use.
Polyurethane, in contrast, offers the elasticity of rubber while delivering superior mechanical performance. With higher tensile strength, greater abrasion resistance, and better load-bearing capacity, polyurethane pads are a preferred choice for industries requiring durable and long-lasting solutions.
| Property | Rubber | Polyurethane |
| Durability | Moderate | High |
| Abrasion Resistance | Low | Excellent |
| Load-Bearing Capacity | Limited | Superior |
| Customization Options | Minimal | Extensive |
| Longevity | Shorter Lifespan | Longer Lifespan |

Advantages of Polyurethane Die Pads
Industrial polyurethane die pads provide significant advantages for metal forming applications, making them a preferred material in the industry. Key benefits include:
Strength and Longevity
Polyurethane pads are engineered to withstand high pressures and repeated use without degrading. Unlike rubber, which can crack, tear, or lose its shape over time, polyurethane maintains its structural integrity even under extreme conditions. Its resistance to abrasion and tearing further enhances its strength, making it ideal for heavy-duty applications.
This robustness reduces the frequency of replacements and minimizes downtime, leading to significant cost savings over the long term. Additionally, polyurethane’s resistance to chemicals, acids, and bases enhances longevity, even in harsh environments. PSI Urethane stocks hand-poured urethane pads and urethane sheets, they are typically in our natural color, and feature durometers from 60A to 90A.
Customization and Versatility
One of the standout features of polyurethane is its ability to be tailored to specific needs. Whether you require a specific hardness, thickness, or design, polyurethane pads can be customized to meet the unique demands of your application. This flexibility allows industries to purchase only what they need, reducing waste and optimizing resource usage.
Furthermore, the option to create pads in custom sizes makes sure that no material goes unused, providing both economic and environmental benefits. Polyurethane’s adaptability guarantees optimal results across various industries, from manufacturing to heavy machinery. Custom formulations from PSI Urethanes are as follows:

Enhanced Performance
Polyurethane offers superior energy absorption and resilience compared to rubber. This enhances the precision and quality of metal forming processes, reducing defects and improving overall efficiency. The self-sealing nature of polyurethane prevents cutting blade deflection caused by scarred surfaces or previous cut marks, ensuring a clean and accurate cut every time.
Moreover, polyurethane cutting surfaces are easy to clean and maintain, with both sides of the pad being fully usable. Its resistance to chemicals, oils, and environmental factors provide consistent performance in challenging conditions, further solidifying its reputation as a high-performing material for industrial applications.
Applications of Polyurethane Die Pads in Metal Forming
Polyurethane die pads are utilized across a range of industries, each benefiting from their unique properties:
