High density foam with soft bed and backrest

High-density foam is used for soft packaging of bedside backrest. High-density foam is a sponge that weighs more than 45 kilograms per cubic meter. Now that sponge technology has improved, it is no longer desirable to judge the density of sponge only by weight. The sponge of this technology has high density and much lighter weight than the previously processed sponge. High-density foam is no longer only judged by weight.

Density is an important index of matter.

Density is an important index of matter. A high density of sponge means that the smaller the gap, the greater the mass.

More professional technical standards

The sponge technology has been improved, and the density is no longer judged by weight. But through more professional technical standards to judge the density of sponge pad.
