What is the difference between EVA foam, EPE -Schaum, and sponge foam

1. EVA-Schaum (Ethylenvinylacetat)

Merkmale:

• Fine and uniform cell structure (glatte Oberfläche)
• High elasticity and toughness
• Good water resistance and durability
• Can be stirbend, hitzebildete, laminated, oder gedruckt easily
• Density range: 30–300 kg/m³
• Verfügbar in various colors and hardness levels

Typical Uses:

• Sports mats, yoga blocks, swimming belts
• Packaging inserts (high-end electronics, Werkzeuge)
• Shoe soles, kneeling pads, Spielzeuge

Pros: Smooth finish, dauerhaft, anpassbar, ungiftig
Cons: Slightly more expensive than EPE

2. EPE-Schaum (Expandiertes Polyethylen)

Merkmale:

• Lightweight with larger air bubbles / open cells
• Soft and flexible, excellent Stoßdämpfung
• Water and chemical resistant
• Density range: 15–50 kg/m³

Typical Uses:

• Verpackung (Elektronik, Glas, Möbel)
• Edge protectors, foam tubes, Isolierung

Pros: Low cost, good cushioning, wiederverwendbar
Cons: Rougher surface, less firm than EVA, not suitable for precision cutting

3. Schwammschaum (Polyurethane or PU Foam)

Merkmale:

• Offenzellige Struktur (soft and breathable)
• Very compressible and comfortable
• Absorbs water easily
• Density range: 10–60 kg/m³

Typical Uses:

• Seat cushions, Schallabsorption, cosmetic sponges
• Cleaning products, gaskets, Polsterung

Pros: Very soft, komfortabel, low cost
Cons: Absorbs water, poor durability outdoors, not suitable for heavy loads
