Rogers PORON foam vs. EPDM foam

Foam: Differences, Advantages, and Disadvantages

Rogers PORON Foam

Ekotech Converting Company - Poron - Pianka EPDM

Advantages:

  • High Durability: Resistant to degradation over time, maintaining performance.

  • Excellent Compression Set Resistance: Retains shape and effectiveness after repeated use.

  • Good Energy Absorption: Provides excellent cushioning and impact protection.

  • Consistency: Provides uniform performance across different batches.

Disadvantages:

  • Cost: Typically more expensive than EPDM foam.

  • Limited Chemical Resistance: Less resistant to certain chemicals compared to EPDM (depending on the PORON chosen).

Differences:

  • Material Composition: PORON is a microcellular polyurethane foam.

  • Density and Firmness: Generally, PORON foam has a higher density and a more consistent firmness compared to EPDM.

  • Compression Set: PORON foam has an excellent compression set resistance, meaning it can retain its shape and cushioning properties even after prolonged compression.

  • Durability: PORON foam is highly durable and resistant to wear and tear.

  • Applications: Frequently used in applications requiring cushioning, energy absorption, and vibration dampening.

EPDM Foam

Ekotech Converting Company - Poron - Pianka EPDM

Advantages:

  • Cost-Effective: Generally cheaper than PORON foam.

  • Good Weather Resistance: Excellent resistance to ozone, UV, and weathering.

  • Chemical Resistance: Resistant to a wide range of chemicals and solvents.

  • Versatile: Suitable for various sealing and insulating applications.

Disadvantages:

  • Compression Set: Tends to deform more permanently under prolonged compression.

  • Durability: May not last as long as PORON in high-stress applications.

  • Energy Absorption: Lower impact protection and cushioning compared to PORON.

Differences:

  • Material Composition: EPDM is a type of synthetic rubber.

  • Density and Firmness: Generally, less dense and less firm compared to PORON.

  • Compression Set: EPDM foam has moderate compression set resistance.

  • Durability: Good durability but may degrade faster than PORON in certain environments.

  • Applications: Commonly used for weatherstripping, seals, and insulation.

Which Product is Better?

The choice between Rogers PORON foam and ordinary EPDM foam depends on the specific application requirements:

  • For applications requiring high durability, consistent performance, and excellent cushioning: Rogers PORON foam is typically the better choice despite its higher cost.

  • For applications where cost is a major consideration and moderate performance is acceptable: EPDM foam is a suitable and cost-effective option.

Application Examples:

  • PORON Foam: Medical devices, footwear insoles, electronic device cushioning, high-performance seals and gaskets.

  • EPDM Foam: Automotive weatherstripping, HVAC seals, outdoor equipment, general-purpose gaskets

In summary, PORON foam is superior for high-performance, long-lasting applications requiring excellent cushioning and minimal compression set. EPDM foam is more suitable for budget-sensitive projects where good weather resistance and moderate durability are sufficient.
