Introducing PORON® 40V0 Foam: Expanding What’s Possible with Flame-Rated Polyurethanes

Engineers designing modern electronic, transportation, and defense systems face a familiar challenge: meeting stringent flame safety standards without adding cost or compromising design flexibility. Many polyurethane foams struggle to achieve high flame ratings such as UL 94 V-0 in the thin, soft grades needed for today’s compact assemblies. In other cases, silicones may meet the requirements but introduce unnecessary expense when extreme temperature or water sealing aren’t part of the specification.

That’s where PORON® 40V0 polyurethane foam from Rogers Corporation stands out. Developed to give designers a more versatile option for V-0 flame compliance, the material combines softness, conformability, siloxane-free and halogen-free chemistry, and long-term reliability. The result is a foam that protects sensitive components and meets safety goals while helping manufacturers simplify material selection and control costs.

Designed for Versatility and Compliance

PORON 40V0 foam delivers UL 94 V-0 flame performance in thicknesses as low as 3 mm, an achievement that enables safer, slimmer product designs. It maintains excellent compression set resistance, ensuring consistent sealing performance over time, even in environments with vibration or mechanical stress.

This balance of flame safety, softness, and stability makes PORON 40V0 foam a smart choice for engineers who need reliability without overspecification.

Applications Across Key Industries

The need for V-0 flame-rated materials spans industries, from electronics and energy storage to transportation and defense. PORON 40V0 foam is proving especially valuable in:

• Electronics and Data Centers: Flame-rated gap fillers that also reduce acoustic fan noise.
• Automotive and Transportation: Control modules, EV battery components, and interior assemblies transitioning from FMVSS 302 to UL 94 V-0.
• Battery Energy Storage Systems (BESS): Reliable flame performance and consistent compression for densely packed module designs.
• HVAC and Building Systems: Acoustic and sealing performance under variable thermal and humidity conditions.
• Defense and Aerospace: Lightweight interior and electronic components where space constraints, safety, and compliance all intersect.
