The sponge used for sofa filling is mainly divided into three categories: conventional sponge is a conventional polyether and TDI as the main body of the sponge. It is characterized by good resilience, softness and breathability; High resilience sponge is a kind of active polyphosphorous sponge with TDI as the main body, which is characterized by excellent mechanical energy and good elasticity. Large compression load, fire resistance, good air permeability; Random hole sponge is a kind of sponge with internal pores similar to natural seaweed of different sizes. It is characterized by good elasticity and excellent buffering during compression and rebound.
2, Down stuffing
Down as sofa stuffing, sitting comfortable, long-term use of small deformation, the disadvantage is slow rebound, the cost is high. Generally used in conjunction with sponge in the senior sofa, suitable for use as a cushion.
3, Artificial cotton filler
Artificial cotton as sofa filler, excellent softness, comfortable sitting, but poor mechanical properties, compression load is small, should only be done as a cushion.
