What is the difference between high density sponge and high resilience sponge?
Sponge in accordance with the density distinction can be divided into high-density and low-density sponge, according to the elasticity distinction, can be divided into high rebound and slow rebound sponge, elastic sponge has a high density also has a low density, the degree of hardness and softness is not the same.
High-density sponge definition and characteristics
Usually we refer to the high-density sponge is the sponge per cubic meter of sponge weight of 45 kg or more. But now the sponge process has been improved, not simply by weight to measure the density of sponge, now the process of sponge, high density, weight than the previous processing of sponge much lighter.
High-density sponge uses
High-density sponge, more holes, very full, often used to do sound-absorbing cotton, sofa cushions, soft bags and other materials.
High density sponge hardness in general, high density sponge hardness is also high, but do not exclude some high density sponge will add super soft additives, so that the sponge becomes super soft, used to do sound-absorbing cotton, sofa cushions, soft package materials. Medium-density, low-density sponge used to do general protection materials. The same density of the sponge is not the same degree of softness.
High resilience sponge characteristics
High rebound sponge is the main component of polyurethane, the production of sponge bubble hole diameter mixed distribution, skeleton thickness is different, there is a large open rate, in the pressure will be in different deformation state to produce different support rebound force.
In summary, high resilience sponge is a sponge of high elasticity, easy to restore the original shape, and high elasticity sponge has high density and low density, customers can order high resilience sponge and high density sponge according to demand.
