PORON® Polyurethane Gaskets
PORON® industrial polyurethane materials from Rogers Corporation are used in demanding applications that require long-term compression set resistance, sealing, cushioning, impact protection, vibration management, gap filling, and durable foam performance.
SRP converts PORON® polyurethane materials into custom die-cut gaskets, seals, pads, strips, cushions, display protection components, EV battery pads, and other precision foam components. Whether your application requires a soft low-closure-force gasket, a firm support pad, a thin display protection material, or a specialty foam for water sealing, flame resistance, or sustainability-focused design, our team can help match the right PORON® material to your application requirements.

PORON® Material Selection Guide
Use these quick comparison charts to identify the PORON® polyurethane material family or grade that best fits your sealing, cushioning, vibration-management, bonding, or gap-filling application.
PORON® 4701 Series Selection Guide
PORON® 4701 Series materials are commonly used for general gasketing, sealing, cushioning, gap filling, and vibration management. Softer grades are better suited for low closure force and conformability, while firmer grades provide more support, compression resistance, and energy management.
| Material | Feel / Performance | Best For | Key Strength | Typical Applications |
|---|---|---|---|---|
| PORON® 4701-30 | Very Soft | Low closure force applications | Excellent conformability | Flexible gaskets, gap filling, cushioning, vibration isolation |
| PORON® 4701-40 | Soft | General-purpose sealing | Balance of softness and support | Gaskets, seals, vibration management, gap filling |
| PORON® 4701-50 | Firm | Higher energy management | Firmer support and durability | Gaskets, cushioning, shock management, impact protection |
| PORON® 4701-60 | Very Firm | Demanding environments | Strong support and compression performance | Gasketing, sealing, gap filling, durable support applications |
PORON® 4790 Series Selection Guide
PORON® 4790 Series materials are commonly used in display protection, compact electronics, cushioning, shock absorption, and vibration-control applications where controlled compression and impact protection are important.
| Material | Feel / Performance | Best For | Key Strength | Typical Applications |
|---|---|---|---|---|
| PORON® 4790-92 | Extra Soft / Slow Rebound | Delicate assemblies | Slow rebound and soft cushioning | Cushioning, display protection, gap filling, vibration control |
| PORON® 4790-79 Display Back Pad | Thin / Firm | Thin electronic assemblies | Shock absorption in compact designs | Display protection, LCD gasketing, vibration control |
| PORON® ShockSeal™ 4790-79 | Impact Protection | Shock-heavy applications | Energy absorption and impact management | Protective gaskets, cushioning, shock absorption, sealing |
PORON® Specialty Materials Guide
PORON® specialty performance materials are designed for applications that require more targeted foam performance, including EV battery pressure management, ultra-thin compression, flame resistance, display bonding, and sustainability-focused design.
