How do you make sponge for car seat cushion?
Just like foaming, the same material, different manufacturing processes, makes different things;PU sponge mainly includes polyester and polyether. It can be sliced or rolled. It can also be processed according to customers' requirements, such as compound processing, hot pressing and blasting, opening hole treatment, etc.. PU sponge because of its thermal insulation, sound absorption, shock absorption, flame retardant, antistatic, breathable performance and other characteristics, it relates to a variety of industries, including the automotive industry, battery industry, cosmetics industry, bra and underwear manufacturing and high-end furniture manufacturing etc..
Foaming processing. 80 ethylene vinyl acetate (EVA), 20 APAO PT 3385, 20 copies of two azo formamide, L9 CaCO and 0.6 two cumene peroxide mixed together, foaming in the mold, and the mechanical force break obturator can be made of foam sponge. Its density (d) is 0.028 g/cm, and the compressive hardness of 25% is 1.9 KPa.
The foamed resin, foaming aid and adhesive resin (which makes the finished product have adhesive property) are mixed together;
