EPP stands for Ethylene Propylene Rubber, which is a highstrength, lightweight, and flexible material made from ethylene propylene copolymer. It has excellent impact resistance, chemical resistance, and thermal stability, making it suitable for applications where durability and reliability are critical. The unique feature of EPP is its ability to be easily molded into complex shapes without losing strength or flexibility.

EPS (Expanded Polypropylene), on the other hand, is a thermoplastic polymer made from polypropylene. It is known for its low density, making it an excellent choice for packaging products due to its lightweight nature. However, EPS has lower strength than EPP, and it's not as flexible, so it's more suited for applications requiring lightweighting but with moderate durability requirements.

In conclusion, while both EPP and EPS materials have their unique features, EPP offers superior performance in terms of strength, flexibility, and heat resistance, making it a preferred choice for many industries where highquality, durable, and lightweight components are required.
