Generally high-density foam hardness is also high, but do not rule out some high-density foam additives are added ultra-soft sponge high rebound model, so that the sponge becomes ultra soft, sound-absorbing cotton used to make, sofa cushions, soft package material. Medium density, low density foam used for general protective material. The hardness of the foam of the same density is not the same. With the absorption of external forces, delicate, soft, comfort features, in car, furniture, health care, high resilience foam toys, etc., to meet the various market requirements. Density is an important indicator species, high density foam, indicating that there is a small gap, the greater the quality of high-density foam density is generally said that more than 30 high-resilience foam sponge purposes can be called high-density foam. Mainly used for good flexibility, toughness, good product. Density calculation method is mainly: weight / volume. It is an important indicator substance density, high resilience foam density sponge manufacturers, which illustrate the gap is small, there is a large hardness sponge in the industry is a method to distinguish density divided, the density of the sponge is KG / M3. Is the weight per cubic meter sponge. Liangping County high resilience foam, longtime fitness equipment, high resilience foam application Ltd. provided by longtime fitness equipment accessories.
