EPE vs EVA and Sponge

EPE (Expandable/Polyethylene), also known as pearl cotton. It is composed of low-density polyethylene glycol by physical foaming to produce a myriad of independent bubbles.

EPE material

It overcomes the shortcomings of common styrofoam, such as fragility, deformation and poor recovery. It has water-proof, moisture-proof, shock-proof, sound-proof, heat-insulating, good plasticity and toughness. Recycling, environmental protection, strong anti-collision and many other advantages.


The commonly used sponge is called polyurethane soft foam rubber. Polyurethane is the most common polymer material in life and is widely used in the production of various "sponge" products. And elastic materials for shock absorbers and anti-friction applications.


EVA is characterized by good softness, rubber-like elasticity, good blending with fillers, and good coloring and molding processability. EVA can be injection molded, extruded, blow molded, calendered, Rotomolding vacuum thermoforming, foaming, coating, heat sealing, welding and other molding processes can be used as building materials for waterproofing, arson, and sound insulation.

EPE material


The sponge is yellowish and elastic, lighter than EPE and EVA.
EVA is black and has a hard surface, which is the heaviest of the three.
EPE pearl cotton is white, it will make a sound when pressed by hand, and the pressed place will be sunken.
