Q&A of EPS
Chemical Properties of EPS
The expandable polystyrene is a small granular resin. Most of such particles are beads produced by suspension polymerization, while larger diameter particles are also obtained by pelletizing. The size of the beads used is determined by the minimum wall thickness of the final foam product. It is easier to make larger particles to make low-density foam products, and smaller particles are easier to make into evenly filled parts.
The properties of a foamed plastic product depend on the base polymer, but are greatly affected by the density of the foam. A EPS foam product with a density of 11b/ft3, 97% of which is air, has poor mechanical properties. The air contained in the foam is divided into millions of cells, and their presence gives the polymer foam a number of valuable properties.
