low density
high density
high compressibility
Forklaring
EPS is known as one of the world’s most effective and lightweight insulation and packaging materials. It has low thermal conductivity and is moisture resistant, so it is often used as insulation against changing temperatures. Its high compressive strength gives it excellent shock absorption properties, making it an efficient packaging material.
