EXPANDED POLYPROPYLENE (EPP)
>
> EPP is similar to EPS, but it has a shape memory allowing it to
> maintain its structure and to deform without breaking. This material
> is mostly used in sporting goods, automotive components, electronic
> packaging, stuffed products and more.
>
> EPP density range, from 20 g/l through 200 g/l
> Tensile strength (kPa) 270 to 1930
> Tensile elongation (%) 21 to 7.5
>
> Compressive strength (kPa)
> 25% strain 80 to 2000
> 50% strain 150 to 3000
> 75% strain 350 to 9300
