PORON is a brand name of microcellular urethane foam developed by Rogers Corporation. PORON is a high-performance, open-cell foam that is designed to provide excellent cushioning, impact resistance, and energy absorption properties.

The PORON foam is a closed cell foam, meaning the cells are not connected to each other. This makes it resistant to water and other liquids, making it ideal for use in applications where water resistance is important.

PORON foam is also known for its good compression set resistance, which allows it to maintain its shape and thickness even after repeated compression. Additionally, PORON foam is highly durable and resistant to tearing, making it suitable for use in applications where repeated impacts and abrasion are expected.

Due to its excellent cushioning and impact resistance properties, PORON foam is commonly used in a wide range of applications, including footwear, athletic padding, medical devices, electronic equipment, and industrial gaskets and seals.

• Excellent cushioning and shock absorption: PORON foam is designed to provide superior cushioning and shock absorption properties, making it ideal for applications where impact resistance is important.
• Good compression set resistance: PORON foam is highly resistant to compression set, which means it can maintain its shape and thickness even after repeated compression. This makes it ideal for applications where the foam will be subjected to repeated pressure or impact.
• Water resistance: PORON foam is closed cell, meaning the cells are not connected to each other. This makes it resistant to water and other liquids, making it ideal for use in applications where water resistance is important.
• Durable and resistant to tearing: PORON foam is highly durable and resistant to tearing, making it suitable for use in applications where repeated impacts and abrasion are expected.
• Breathability: PORON foam is designed to be breathable, which means it can allow air to pass through it. This makes it ideal for use in applications where moisture management is important, such as in footwear and athletic padding.
• Low compression set creep: PORON foam has low compression set creep, which means it can maintain its original thickness and shape over time, even under sustained pressure.

Overall, the superior cushioning, shock absorption, and durability properties of PORON foam make it a popular choice in a variety of applications, including footwear, athletic padding, medical devices, electronic equipment, and industrial gaskets and seals.

The chemical resistance of PORON foam depends on the specific type of PORON material. However, in general, PORON foam is resistant to a wide range of chemicals, including oils, solvents, and acids.

Specifically, PORON foam is resistant to a range of common chemicals, such as:

• Petroleum-based oils and fuels
• Acids and bases
• Alcohols
• Water and humidity
• UV light

However, PORON foam may not be suitable for use in applications where it will be exposed to strong oxidizing agents or some chlorinated solvents.

It’s important to note that chemical resistance can be affected by factors such as temperature, concentration, and exposure time. Therefore, it’s recommended to consult the manufacturer’s technical data sheet for specific information on the chemical resistance of a particular type of PORON foam.
