Sofa cushion filling stuff fill what is more durable?
Soft polyurethane foam (commonly known as sponge): sponge used for sofa filling, mainly divided into three categories: conventional sponge is a regular polyether and TDI as the main body of the sponge. The utility model has the advantages of good resilience, softness and breathability; the high resilience sponge is a sponge generated by active phosphorus accumulating and TDI as the main body, and has the advantages of excellent mechanical property and good elasticity. The utility model has the advantages of large compression load, good combustion resistance and good air permeability; the irregular hole sponge is an inner hole with different sizes of natural algae similar to a sponge, and is characterized by good elasticity, excellent cushioning property when compressed and rebound.It is recommended to combine the high resilience sponge with the hole sponge and combine down or artificial cotton to increase comfort and service life.
Artificial wadding: artificial wadding made of sofa stuffing, soft and comfortable, comfortable to sit, but poor mechanical performance, low compression load, only cushion.
Down filling: down for sofa filling, comfortable sitting, long-term use of small deformation, drawback is slow rebound, high cost. Generally used in conjunction with the sponge in the advanced sofa, or suitable for cushion use.
