Expanded polyethylene foam, also known as EPE, is a molded semi-rigid, non-crosslinked, closed-cell polyethylene foam that is often denser and stronger than its open-cell counter parts.
Molded EPE planks are made with a very uniform cell structure. The consistent cell structure results in a foam with superior physical properties that have the same multi-directional mechanical values. This creates a material that cuts more consistently, has significantly less concavity and shrinkage when die cutting, as well as, cleaner, more precise cuts when CNC cutting or machining.
Having higher strength to weight ratios than Extruded Polyethylene and Crosslink Polyethylene allows you to use less EPE, resulting in thinner walls and smaller overall package sizes with less dimensional weight.
Expanded Polyethylene Foam has the following characteristics:
- Moisture and weather resistant
- Tear and puncture-resistant
- High compressive strength
- Multi-Directional impact resistance
- Meets Mil-Spec requirements – Not if brand specific or density based
- Thermal insulation R4 per inch
- Multiple strike energy management
- Dimensional stability
- Impact and shock absorption
- Vibration dampening
- Excellent compressive creep properties
- Shatter Proof
- Bacteria, chemical, grease, mold, oil and solvent-resistant
- Less concavity when die-cut (compared to PE and XLPE)
- Coast Guard approved
- Ozone friendly
- Sonic transmission control
- Chemically inert
- High load bearing capacity
- Cost/labor efficient
