EVA foam and XPE foam: material comparison and characteristic analysis

EVA foam and XPE foam, as two important members in the field of plastic materials, each play a key role in specific application scenarios. Although they are similar in some respects, a closer comparison reveals significant differences along several key dimensions.

Material comparison

EVA foam, full name ethylene-vinyl acetate copolymer foam, is a lightweight and elastic material. It has excellent impact resistance, wear resistance and weather resistance, making it widely used in packaging materials and other fields. EVA foam can also adjust its hardness and elasticity by changing the formula and process to meet the needs of different scenarios.

XPE foam, cross-linked polyethylene foam material, is known for its high foaming rate and excellent elasticity. It is made using advanced cross-linking technology and has excellent resilience, thermal and sound insulation and anti-slip properties. XPE foam is non-toxic and odorless and meets environmental protection standards, so it is widely favored in fields such as baby crawling mats, high valued products and car interiors.

Comparison of weight and density

In terms of weight, XPE foam is generally lighter than EVA foam. This is because XPE foam has a higher expansion rate and contains a large number of tiny bubbles inside, resulting in a lighter weight. Although EVA foam also has certain lightweight characteristics, its weight is usually slightly heavier than XPE foam at the same volume.

In terms of density, XPE foam generally has a lower density, which is also a reflection of its lightweight properties. The density of EVA foam varies depending on the specific formula and process, but in general, its density is relatively high. This difference in density makes XPE foam an advantage in applications where lightweight materials are required.

Price comparison

In terms of price, XPE foam is usually more expensive than EVA foam. This is mainly due to the relatively complex production process of XPE foam, which involves cross-linking technology and has higher requirements for raw materials. In addition, XPE foam has excellent performance in terms of properties such as resilience, thermal and sound insulation, etc., which also provides support for its price.
In contrast, the production process of EVA foam is relatively simple and the cost is low, so the price is relatively affordable. This makes EVA foam highly competitive in the market in some areas that have strict cost requirements.

It is important to note that price is not the only factor in selecting materials. When choosing between EVA foam or XPE foam, factors such as material performance, application scenarios, and environmental protection requirements need to be comprehensively considered. For example, in situations where higher resilience and thermal and sound insulation are required, XPE foam may be more suitable; while in situations where cost requirements are stricter, EVA foam may be more advantageous.


There are obvious differences between EVA foam and XPE foam in terms of material, weight, density and price. When choosing to use these two materials, we need to conduct a comprehensive evaluation based on specific needs and scenarios to select the most suitable material. At the same time, with the continuous advancement of technology and the development of the market, we expect these two foam materials to continue to optimize performance, reduce costs, and play an important role in more fields in the future.
