Supply of high density fireproof foam sponge sponge car seat manufacturers offer

Supply of high density fireproof foam sponge sponge car seat manufacturers offer quality car seat sponge, the sponge is mainly determined by the density and hardness. Car seat main material is a polyurethane foam, is generally a molding die, according to the design for the car. Generally high-density foam hardness is also high, but do not rule out some high-density super soft foam additives are added, so that the sponge becomes ultra soft, sound-absorbing cotton used to make, sofa cushions, soft packing material. Medium density, low density foam used for general protective material. The hardness of the foam of the same density is not the same. Supply of high density fireproof foam sponge sponge car seat manufacturers offer sponge is usually foamed polyethylene or foamed polypropylene 1. In general, do not investigate hardness, commonly ppi (per square inch mesh count) metrics, such as 10ppi, 20ppi, The higher the number, the harder the sea. 2 of the sponge-like hardness, generally using C type Shore hardness measurement, the greater the value the more hard; there is also represented indentation hardness (N) or Kgf chemical sponge: polyurethane soft foam rubber, polyurethane is life. The most common type of polymer material, widely used in the production of "sponge" products. As well as shock absorbers, anti-friction purposes of elastic material, such as shoe soles, tractor tank track substrate. PU foam including polyester and polyether can be sliced ??or cut volume, according to customer requirements can also be complex, hot pressing and blasting holes processing. PU foam because of its insulation, heat insulation, sound absorption, shock absorption, flame retardant, antistatic, breathable performance and other characteristics, it is involved in a variety of industries, including the automotive industry, battery industry, cosmetics industry, brassieres underwear manufacturing and high-end furniture manufacturing.
