AOWEIDA
A wrong spec means a wrong sample. Before you email a supplier, lock down these three numbers — they decide 90% of how the foam behaves.
1. Density (kg/m³)
Density drives weight, firmness and cost. Typical ranges:
- 30–45 kg/m³ — ultra-light, yoga mats, padding.
- 60–100 kg/m³ — general footwear, packaging.
- 120–200 kg/m³ — structural, high-load inserts.
2. Hardness (Shore C)
We rate EVA on the Shore C scale (not Shore A). Common range is 15C (very soft) to 80C (firm). A yoga mat might be 35–45C; a shoe midsole 45–60C; a toolbox insert 60–75C.
3. Thickness & tolerance
Standard sheet thickness runs 1–100 mm. Tell us the tolerance you need — ±0.2 mm is achievable on CNC-routed parts, ±0.5 mm on molded sheets.
Bonus: VA content & color
VA content (%) affects clarity and flexibility. Color is unlimited via masterbatch — just send a Pantone or sample swatch.
