What is difference between PE foam and EPDM foam?

Polyethylene (PE) foam and Ethylene Propylene Diene Monomer (EPDM) foam are two popular types of foam widely used in various industries.

PE foam is a closed-cell foam made of polyethylene (a type of plastic) through a process known as extrusion. It is available in different densities, thicknesses, and colors. It has exceptional shock-absorbing properties and provides excellent insulation against heat and cold. PE foam is commonly used in packaging, insulation, cushioning, and gasketing applications.

EPDM foam, on the other hand, is made by blending ethylene propylene diene monomer rubber (a synthetic rubber) with various other materials. It has a closed-cell structure and is very resistant to UV light, weather, and ozone. It has excellent resistance to water, steam, and chemicals and can withstand a wide range of temperatures. EPDM foam is used extensively in applications where sealing, weatherstripping, and vibration-dampening are important.

The primary difference between PE foam and EPDM foam is in their material composition and properties. PE foam is a type of plastic foam and is known for its shock-absorbing properties, while EPDM foam is a type of rubber foam and is known for its resistance to weather, water, and chemicals.

In summary, both PE foam and EPDM foam have their unique properties and applications. While PE foam is ideal for cushioning and insulating applications, EPDM foam is best suited for sealing, weatherstripping, and vibration-dampening applications. Choosing the right type of foam will depend on the specific requirements of the application.
