EPP and EPS are two of the most common types of foam used in various industries. They share some similarities but also have distinct differences that make them suitable for different applications.

EPP stands for Expanded Polystyrene, which is a type of extruded polystyrene foam. It has been around since the 1950s and is known for its high density and excellent insulation properties. This makes it an ideal material for constructing walls, roofs, and other structural elements due to its ability to provide soundproofing and energy efficiency.

On the other hand, EPS (expanded polypropylene) is another type of expanded foam that is commonly used in construction. Unlike EPP, EPS is made with propylene rather than styrene, making it slightly lighter and more costeffective. However, its insulation properties are not as good as those of EPP, and it is less durable when subjected to extreme temperatures or impact.

In terms of durability, both EPP and EPS can withstand wear and tear under normal conditions. However, EPP is more resistant to impact and provides better sound insulation compared to EPS.

Another difference between EPP and EPS is their flexibility. EPP is highly flexible and can be molded into almost any shape. On the other hand, EPS is less flexible and may break or crack if subjected to excessive pressure or heat.

In summary, while EPP and EPS are similar in many ways, they have distinct differences that make them suitable for different applications. When choosing between these two foams, consider your specific needs and requirements before making a decision.
