- What is closed-cell polyethylene foam good for?
- Sealing, gasketing, cushioning and vibration damping. The closed cells block water and air, so it works for weatherstripping and packaging where open-cell foam would absorb moisture.
- How thick is this sheet?
- 3/16 inch, about 4.8 mm. That is thin enough to line tight gaps but too thin for heavy impact padding.
- What temperature range does it handle?
- -110°F to 180°F. It stays flexible in cold storage and outdoor winter use, and holds up in warm enclosures.
- Does the adhesive stick to rough or dusty surfaces?
- Not reliably. Pressure-sensitive adhesive needs a clean, dry, smooth surface; dust, oil or texture weakens the bond.
- Can it be cut to size?
- Yes. PE foam cuts easily with a knife or scissors, and the 54-inch width lets you cut large pieces without seams.
- How does it compare with neoprene or EVA foam?
- It is lighter and more moisture-resistant but softer and less resilient. Choose neoprene for oil and chemical resistance, EVA for firmer, springier cushioning.
