- Shock Absorption: Dissipates up to 90% of kinetic energy.
- Moisture Resistance: Maintains structural integrity in humid environments.
- Lightweight Density: As low as 0.03g/cm³ for easy handling.
Applications
1. Packaging Industry:
- Precision-cut linings for fragile electronics, ceramics, and glassware.
- Bespoke laptop casings and specialized inserts to reduce breakage.
2. Sports & Leisure:
- Yoga mats, orthopedic shoe insoles, and gym padding.
- Marathon-ready midsoles for athletic footwear.
3. Industrial Uses:
- Wall and rooftop insulation panels for energy efficiency and noise reduction.
- Vibration-dampening gaskets for machinery stability.
4. DIY & Creative Projects:
- Kindergarten tactile toys (e.g., alphabet puzzles).
- Home décor (3D wall art) and cosplay props.
- Pandemic-era safety partitions combining affordability with effectiveness.
Advantages
- Lightweight: Reduces shipping costs and ergonomic strain.
- Shock Absorption: Neutralizes over 70% of impact forces.

- Industrial use: >100kg/m³ for durability
- Lightweight applications: <100kg/m³
- Supplier Reliability:
- Verify eco-certifications and user reviews.
- Request samples for tactile evaluation.
- Maintenance Tips:
- Gentle cleaning extends lifespan.
Ultimately, EVA foam board transcends traditional materials—offering efficiency, sustainability, and endless creative potential.
FAQ
FAQ1: What’s EVA foam board made of?
It’s composed of ethylene-vinyl acetate copolymer with a closed-cell structure, balancing pliability and resilience. Crosslinking agents enhance rigidity, while its PVC-free, non-toxic composition aligns with green standards.
FAQ2: Why choose EVA foam board?
Benefits include lightweight durability, shock absorption, waterproof qualities, ease of customization, eco-friendliness, and cost-effectiveness.
FAQ3: Where is EVA foam board commonly used?
Applications range from protective packaging, sports equipment, construction insulation, children’s toys, to home decoration.
FAQ4: Is EVA foam board eco-friendly?
Yes! It’s recyclable, low-emission, and biodegradable. Look for certifications like REACH/ROHS for verified sustainability.
FAQ5: How to select the right EVA foam board?
Consider thickness, density, and certifications. Heavy-duty projects need thicker sheets (>10mm), while crafts benefit from softer, thinner options. Always purchase from reputable suppliers.
