                                 EPS

EPS foam is a thermoplastic material, after heating foaming, each cubic meter volume contains 3-6 million

individual closed bubbles, containing air volume of more than 98%, Such a structure gives it many properties.

Since the density can be as low as 10-30kg/m3, EPS is the lightest packaging material available, and at higher

loads, the material Material will be bent, and when it is shaken or falling to the ground, it acts as a buffer and

shock proof, and because the air's thermal conductivity is small and enclosed in the foam Cannot convection,

so EPS is a very superior material for thermal insulation.
