EPDM (ethylene propylene diene monomer) is a synthetic rubber that is used for various purposes, including the manufacture of roofing materials, seals, insulation materials, and other rubber products.

EPDM has a number of unique properties that make it suitable for various applications. For example, it is highly resistant to UV radiation and oxidation, which means it can last for a long time without being damaged by the sun or air. It is also resistant to extreme temperatures, both high and low, and it is resistant to many chemical substances.

EPDM is often used as a roofing material because it is strong, flexible, and resistant to extreme weather conditions. It is also often used as a sealing material for windows, doors, and other openings in buildings because it is very elastic and can fit well to different shapes and sizes. It is also used in insulation materials because it is resistant to extreme temperatures and can provide good insulation.
