How to Choose EVA Foam Sheet: Density, Thickness and Hardness

Density, thickness and hardness decide how an EVA foam sheet performs. This guide explains the three key specs and how to match them to your application.

Choosing the right EVA foam sheet starts with three numbers: density, thickness and hardness. Density, usually 25-120 kg/m3, affects weight and support: low-density foam is soft and light, high-density foam is firm and durable. Thickness, from 1 mm to 100 mm, decides cushioning and protection. Hardness, measured in Shore C, ranges from soft (15-25) for comfort to firm (50-70) for structural use. For packaging, choose medium density and thickness for protection without excess weight. For sports padding and floor mats, choose thicker, softer foam. For CNC cutting and gaskets, choose high-density, firm board. Always ask your supplier for a sample before a bulk order. SHENSHUAI offers EVA foam sheet, board and roll in custom density, thickness, hardness, color and size. Contact us with your application and we will recommend the right spec.
