Closed Cell Foam Sheets (PE & EVA)

Closed-cell foam has tiny sealed bubbles that make it waterproof, buoyant and more rigid. It’s ideal for outdoor, marine, insulation and packaging uses. Open-cell foam is softer and breathable, but it absorbs water, so it’s best for indoor cushions and comfort applications.

EVA foam (like EVA30 or EVA75) is softer, more elastic and springy. It’s great where you need comfort, shock absorption or rebound — for example, padding, mats, and marine flotation.

PE foam (like PE30) is firmer and more rigid with better thermal insulation. It’s often used in packaging, automotive, and structural applications where strength is more important.

Yes. Because the bubbles are sealed, closed-cell foam is buoyant and highly water-resistant. EVA foam in particular is often used for flotation and marine projects. Unlike open-cell foam, it won’t soak up water or collapse when wet.

IXPE (cross-linked polyolefin) foam is a flexible, closed-cell foam that’s excellent for insulation and soundproofing. It has low thermal conductivity (≈0.032 W/m·K), resists moisture and chemicals, and can handle a wide temperature range (−70°C to +90°C). Some rolls even have aluminium foil backing or self-adhesive layers for easy installation in HVAC, automotive, marine and building projects.  

Yes. Closed-cell foams are waterproof, UV-resistant and chemical-resistant (including resistance to oils, fuels, detergents, acids and alkalis). That’s why they are popular for boats, outdoor seating, camping gear, and insulation. Just choose the right grade for your exposure to sunlight, heat or heavy use.

Yes. These foams are non-dusting, non-toxic in finished form, and safe to handle with normal workshop precautions. They can be cut with sharp tools like utility knives, saws or CNC routers. Some products come with adhesive backing, which makes installation quicker and cleaner.

Yes. Closed-cell foams like IXPE and XPE thermal wraps provide acoustic damping (reduce vibration and noise) as well as thermal insulation. They are commonly used in building, automotive and HVAC applications for exactly this reason.
