Performance Analysis:
Norseal F-20 outperforms Rogers HT870 in several critical areas:
- Superior Physical Strength and Resilience: Norseal F-20 offers a tensile strength of 30 psi (207 kPa), which is significantly higher than Rogers HT800’s 9.7 psi (67 kPa). This, combined with a higher elongation at break of 60%, ensures that Norseal F-20 provides exceptional durability and flexibility for demanding applications. Its low compression set of less than 5% guarantees long-term performance and reliability under continuous stress.
- Outstanding Flammability and Safety Ratings: Norseal F-20 meets stringent safety standards, passing UL 94 V-0 for flame resistance, FAR 25.853 for aviation standards, and ASTM C1166 for flame propagation. Additionally, it achieves a low flame spread index of less than 35 and impressive smoke density ratings (less than 20 at 1.5 minutes and less than 50 at 4.0 minutes). These properties make Norseal F-20 a safer choice for environments where fire safety is paramount.
- Enhanced Environmental Resistance: Norseal F-20 is designed to withstand harsh environmental conditions, with a wide operational temperature range from -60 to +400°F (-51 to +204°C). It shows no degradation under UV exposure and no cracking when subjected to ozone, per ASTM standards. It also passes FDA extractables compliance, making it suitable for applications involving food contact. Its low water absorption rate of less than 5% ensures material integrity in moist environments.
- Comprehensive Electrical and Thermal Properties: Norseal F-20 excels in electrical insulation with a dielectric strength of 80 volts/mil and a stable dielectric constant of 3.5. Its low dissipative factor of 0.03 and high volume resistivity of 3.39 × 10¹⁴ ohms-cm contribute to its reliability in electronic applications. Thermal properties are equally impressive, with a thermal conductivity of 0.074 W/m°K and a high thermal insulation R-value of 1.94 ft²·h·F°/Btu·in, making it an excellent choice for thermal management solutions.
Norseal F-20 stands out with its superior tensile strength, extensive temperature range, exceptional flame resistance, and comprehensive environmental and electrical properties. These attributes make it the ideal choice for applications requiring robust, reliable, and safe silicone foam rubber. For those seeking top-tier performance and reliability, Norseal F-20 is the preferred option over Rogers HT800.
