What is EPP foam?

Expanded polypropylene (EPP) is a type of polypropylene that comes in a foam shape. Due to its low stiffness, EPP has excellent impact characteristics, allowing it to regain its shape after being struck. Hobbyists use EPP extensively in model aircraft and other radio-controlled vehicles. This is due to its ability to withstand impacts, making it an ideal material for beginner and amateur RC aircraft. In hobbyist radio control model aircraft, expanded polypropylene (EPP) foam is used as a structural material. Unlike EPS, which is friable and easily breaks on impact, EPP foam is able to withstand kinetic impacts well without cracking, maintains its original shape, and has memory foam characteristics that enable it to return to its original shape in a short period of time.
