Overview of PORON ShockSeal Foam

PORON ShockSeal foam is a proprietary cushioning material made by Rogers Corporation. It is widely used in athletic shoes, medical devices, protective gear, and other applications requiring excellent impact absorption and comfort.

Some key features of PORON ShockSeal foam include:

• Outstanding shock absorption – Absorbs over 90% of impact force to protect against injury and fatigue. The foam compresses on impact and then instantly rebounds back to shape.
• Lightweight – Up to 30% lighter than comparable foams, important for athletic footwear.
• Moisture resistant – Maintains cushioning properties even when exposed to sweat and humidity.
• Anti-microbial – Contains an antimicrobial treatment to inhibit odor and bacteria growth.
• Durable – Retains properties over thousands of impacts and use cycles. Much more durable than standard EVA foams.
• Customizable – Available in range of densities, thicknesses, and firmnesses to match application needs.

Key Applications of PORON ShockSeal Foam

PORON ShockSeal is used in a wide variety of products where its unparalleled shock absorption and cushioning are critical:

Athletic and Running Shoes

The foam is extensively used in shoe midsoles, sockliners, tongues, and collars. It provides essential impact protection and stability for runners and athletes in high impact sports. Studies show it can reduce injuries versus shoes without PORON foams.

Protective Gear

ShockSeal foams cushion helmets, pads, guards, and other protective wear. Important for activities like football, hockey, snow sports, and more.

Medical Devices

The foam provides cushioning in braces, prosthetic liners, orthotics, and other medical products. It protects sensitive skin from chafing and irritation.

Mattresses and Pillows

PORON foams provide pressure relief, shock absorption, and cooling breathability in mattresses and pillows for more comfortable sleep.

Additional Applications

Also used in gloves, grips, electronics cases, power tool vibration dampening, and acoustical insulation.

Comparison to Other Foam Materials

vs. EVA Foam

• 2-3x more shock absorbing than basic EVA (ethyl vinyl acetate) foams
• Much more durable and resistant to “packing out” versus EVA
• Better moisture and temperature resistance

vs. Memory Foam

• More shock absorbing and rebound versus viscoelastic memory foams
• Cooler sleeping surface since PORON is open cell vs. memory foam
• Maintains cushioning properties longer than many memory foams

vs. Natural Latex Foam

• Comparable in shock absorption, but lighter in weight
• Won’t degrade or break down over time like some natural latex
• No natural latex allergy issues

vs. Polyurethane Foam

• Significantly more durable and impact resistant
• Cooler and more breathable than solid polyurethane foams
• Lighter in weight than most polyurethanes

Frequently Asked Questions

What is PORON ShockSeal foam made of?

PORON foams are proprietary polyurethane-based foams created by Rogers Corporation. The exact material compositions are trade secrets. Additional chemicals are added to produce the antimicrobial, moisture resistant, and other performance properties.

How long does PORON foam last?

PORON retains over 90% of its original cushioning and impact absorption even after 100,000 impacts. It lasts over 3x longer than many standard foams.

Does PORON foam off-gas or smell?

PORON foams are certified to be low VOC (volatile organic compounds) and do not have a noticeable odor or off-gassing. They meet the GREENGUARD Gold standard for low emissions.

Can you wash items containing PORON foam?

Yes, PORON foam is resistant to water and can be machine washed according to the care instructions for the product. It will retain its cushioning properties after washing.

Is PORON foam recyclable?

Like most polyurethane foams, PORON is difficult to recycle since it is a cross-linked polymer. It should be disposed of properly with other plastics and foams.
