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.
