What Is EPP Foam?
EPP foam is a lightweight and durable plastic material. It is made from expanded polypropylene beads. The material has a closed-cell structure, which makes it strong, flexible, and resistant to impact.
Many industries use EPP foam because it combines low weight with high strength. It can absorb repeated shocks without breaking. It also returns to its original shape after compression.
EPP foam is widely used in automotive parts, protective packaging, and industrial products.
How Is EPP Foam Made?
How Is EPP Foam Made?EPP foam is produced in two main steps.
First, polypropylene resin is expanded into small beads. Steam and pressure are used to create air-filled cells inside each bead. These are called EPP beads.
Second, the beads are placed into a mold. Heat and steam fuse them together. The result is a strong and lightweight molded foam part.
This process is known as EPP molding. It allows manufacturers to create custom shapes for different industries.
