A porous material comprises pores uniformly distributed in a unit volume of the porous material. The porous has a modulus of elasticity less by 10 to 99% than that of a raw material used to manufacture the porous material. The porous material ensures uniformity and consistency of all kinds of performance, has favorable performance and favorable quality, and the uniformity of the porous material effectively reduces the modulus of elasticity. |
