Which are the features of the PE foam if compared to the EVA foam?


PE foam vs EVA foam

In this article, we compare XPE foam with EVA foam.

What is PE foam?

Polyethylene foam, or PE foam is the most popular plastic available today.

One type of polyethylene foam is crosslinked foam. Cross linking makes the foam more resistant against several substances like chemicals. It is also cause excellent thermal insulation, the surface of foam becomes significantly smooth and tender moreover making it much more flexible and lighter due to crosslinking feature. It also helps it bounce back quickly to its original shape during stretches and compresses.

It is not as smooth in appearance as EVA foam, but it is more environmentally friendly, odorless and safer. Compared to EVA foam, XPE is firmer and more resistant to heat.

Main properties:

  • Corrosion resistance
  • Cushion, buffer
  • Lightweight
  • Rebound elasticity, smooth surface
  • Shockproof
  • Sound insulation
  • Thermal insulation
  • Waterproof, moisture-proof
  • Weather resistance

 What is EVA foam?

Ethylene-vinyl acetate, or EVA is a co-polymer of ethylene and vinyl acetate with very fine closed cells, impervious to air and liquids. Vinyl acetate gives the foam its softness and elasticity, so EVA is one of the materials commonly known as expanded rubber or foam rubber.

EVA foams characterized by great elasticity, mechanical and UV resistance, low-temperature toughness, and they are waterproof. It’s got a glossy appearance and it’s available in various colors and densities. And one of its not always loved characteristic, that normal EVA has a distinctive vinegar-like odor.

Both EVA and polyethylene foam known for them shock absorbing qualities and buoyancy. The firm material allows falls or subtle movements.

It can be easily cleaned and disinfected.

Applications of both, PE and EVA foams:

The use of EVA and PE foam is very similar due to their properties, but EVA foam is much more well-liked to be applied in the package that needs a die-cutting process. This method of use is chosen because it is cheaper for EVA, however, PE foam can also be cost-effective choice for customers with special needs.

PE can be found in every industry. It is very popular in the automotive industry where it can be used in car interior parts, e.g. instrument bases, sun visors, coolers, foot mats, air ducts. It is also significant in building insulation, where PE can be used in metal roof panel insulation, as wall and floor underlays, for pipe insulation, for air-conditioners or for sound and heat insulation and for many other applications. There are also many additional products made of this material for sports, like cushion pad, yoga mat, archery target.

The applications of the EVA foam and the polyethylene foam are listed below:

  • Home Appliances
  • Automotive Industry
  • Electronics
  • Footwear
  • Sports
  • Artificial Grass Shock Pad
  • Packaging
  • Health Care
  • Building Insulation
  • Oil Industry
