Black PE foam sheet 600x400x40

Black PE Foam Sheet 600 × 400 × 40 mm – Extreme "Heavy-Duty" Cushioning

A four-centimeter layer of foamed polyethylene in matte black is the absolute top-tier among protective inserts. A sheet with dimensions 600 × 400 mm and a density of 23 kg/m³ (≈ 23 g/m²) quadruples the capabilities of standard 10 mm foam, yet remains surprisingly light. Created for high-value or heavy loads - from aircraft drives and electric engines to collectible bronze sculptures.

🧩 What is PE foam?

Polyethylene foam (LDPE) is created by foaming the granulate with gas, which expands, creating a closed cell structure. Each cell acts as a micro air cushion, providing lightness and powerful energy damping.

• 🔬 Composition: pure LDPE - free from PVC and plasticizers.
• 🛡️ Physical properties: dust-free, resilient, easy to CNC mill.
• 🌡️ Operating range: −40 °C…+90 °C without loss of flexibility.
• 🧪 Chemically neutral: does not react with oils, greases, detergents.
• ♻️ Recycling: LDPE 4 code - after grinding, it returns to the cycle as regranulate.

🧪 Properties of PE foam - damping & elasticity

• 🛡️ 360° XXL damping – 40 mm thickness absorbs > 95 % of impact energy*
• 🪶 Shape memory – deforms under pressure, returns to shape when released.
• 🎨 Masking traces – black color hides scratches, tape remnants, fingerprints.
• 🤫 Resonance damping – minimizes vibrations in road, rail and air transport.

*Typical values, ASTM D1596 test, load ≤ 0.4 kg/cm² at 23 kg/m³.

💧 Moisture resistance and chemical neutrality

• 🌧️ Hydrophobic shield – does not soak, swell or mold.
• 🛡️ Anti-corrosion barrier – separates metal from moisture and oxygen.
• 🧴 Safe for chemicals – neutral for oils, greases, cosmetics.
• 🍯 Indirect food contact – odorless, non-toxic (without certification for direct contact).
• 🌡️ Stability −40 °C … +90 °C – resilient regardless of climate.

📦 Applications in transport and logistics

• 🌀 Wrapping turbines, traction engines, medium power transformers.
• 📑 Super-thick interleaves in steel boxes and sea containers.
• 🔄 Void-fill – filling free spaces in megaboxes (Fefco KLT, XL).
• 🛡️ Milled inserts for 22″ rims, concert columns, museum exhibits.

🏭 Industries using 40mm black PE foam

• 🚀 Aerospace & defence - avionics modules, composite skin components.
• 🔋 E-mobility - battery packs, high-voltage inverters.
• 🎼 Stage & event - 21″ subwoofers, FOH consoles, 4K LED panels.
• 🏗️ CNC machines and robotics - milling heads, harmonic reducers.
• 🗿 Art & collectibles - bronze sculptures, XXL architectural models.

🚚 Logistic and economic benefits

• ⚖️ Light-heavy - huge thickness, minimal impact on the weight of the package.
• 📐 Fewer layers - one 40 mm plate = 4 classic 10 mm sheets.
• ✂️ Fast processing - knife, hot tape, CNC plotter.
• 🔄 Multiple use - maintains parameters for 10+ cycles.
• 📉 Less damage = lower costs of complaints and returns.

⚙️ Technical specifications

• 📏 Format: 600 mm × 400 mm
• 📐 Thickness: 40 mm
• 🪶 Density: 23 kg/m³ (≈ 23 g/m²)
• 🔬 Material: foamed LDPE (closed-cell)
• 🎨 Color: black, matte
