Description
E400 High-Density EVA Foam Sheets — 40–45° Shore C
The softer, more flexible cosplay-and-costume foam, now in fresh 3 mm stock and our largest jumbo sheets yet. E400 is the medium-soft, closed-cell rubber EVA that wraps easily around curves and large body pieces while still holding its shape — warehoused and shipped from Pacoima, California since 1997.
Why choose Avetco E400
- Flexible and easy to shape. At 40–45° Shore C it cuts and heat-forms by hand and wraps smoothly around curved body pieces and large panels.
- Available in white and black. Clean, consistent color — prime straight over it or paint as usual.
- Big jumbo panels, fewer seams. At 47″ x 87″ (220 x 120 cm) you can cut large pieces from a single sheet.
- Consistent, inspected stock. Every container is checked on arrival — uniform thickness and density sheet to sheet.
- Real specs on request. Full manufacturer data sheet and SDS available for production and wholesale buyers.
