Pu cushion(polyurethane foam cushion, pu seat cushion)

Polyurethane foam plastic is small in specific weight therefore the same size of seating pad made of polyurethane foam plastic is only 1/3 to 1/2 in weight when made of latex foam. It can be subject to greater stress and easier to manufacture. The production efficiency is higher particularly by means of molding. It can be produced into various shapes. Furniture seating pad requires the performance of good resilience and comfort. The polyurethane foam plastic can meet this requirement by changing its raw material and recipe. Highly active polyurethane ad cold cure technological process is used, in particular, to obtain soft polyurethane foam of high resilience, which is more suitable for making seating pad.

The earliest way of shaping is by means of cutting, to cut to the shape according to the requirement on the entire piece of foam and then used bond to adhere it to the framework and wrap the peripheral with another material. This method results in the low utilization ratio of polyurethane material, off-cuts and thus uneconomical. Now with the latest technology of molding and foaming to shape PU, the entire cost is reduces and the finish is more appealing.

Another type of sofa is fully in foam so called bucket type seating pad. Which is deep and is shaped in one operation by molding free of framework. This type of sofa offers a comfortable sensation and therefore well received by the user.
